In the February 2025 cold snap, the NOAA station 3 miles southwest of Chadron bottomed out at −32°F. The Kings Canyon station up on the Pine Ridge, 7 miles away and about 730 ft higher, bottomed out at −16°F. The ridge has run milder than town in every big outbreak since 1990 but one, and that's the first thing to understand about fruit trees for Chadron and the Nebraska Pine Ridge.
The map covers the north side of the Pine Ridge escarpment in Dawes County, in Northwest Nebraska's northern Panhandle: Chadron and the college, Dakota Junction and the airport flats, Bordeaux, the buttes on the plain, the White River bottom, and the ridge south past Kings Canyon and Chadron State Park. (That's the escarpment, not the Pine Ridge Reservation in South Dakota.) Crawford sits just past the west edge; there's a section on it below. Type your address in the box on the map to get the number for your own place, and the list of what we sell that has come through it.
How to read this map
The number at every spot is the 30-year planning low, the same number our cold hardiness calculator uses: a safe number to plan around, not the record. The MFTC zone puts it in half zones (−36°F is 3a, −33°F is 3b, −28°F is 4a). Typical winter is an average year's coldest night, the kind of number USDA's map is built on, which is why USDA-style zones read so much warmer than ours. The spring layer shows how many degrees warmer or colder a spot runs than Chadron on a still, clear bloom night.
The middle of the growing ground plans for −33°F (3b), and half of it falls between −34°F and −32°F. Chadron, our reference town, plans for −36°F (3a), with a typical winter low of −19°F. The cold end is the floor around town and the creek and river bottoms, −36°F to −37°F. The warm end is the north face of the ridge, where Lookout Point and the ground at the Kings Canyon station both plan for −28°F (4a). The buttes in between, Isinglass, Trunk and Lovers Leap, plan for −31°F to −33°F.
Why the map looks the way it does
The Pine Ridge escarpment drops more than 1,000 ft from the high table to plains that run north toward the Cheyenne River, and around Chadron its named buttes stand 500 to 740 ft above town, topping out at Flannigan Butte, 4,118 ft. Deep canyons cut the north face, and Chadron Creek and Bordeaux Creek run north out of it to the White River. On a clear, calm night most of a cold pool is made right on the floor as the ground loses heat to the sky, and the canyons add more, carrying cold off the ridge onto the plain. It ends up in the White River bottom north of town, roughly 280 ft below Chadron.
Chadron sits right in that flow, on the valley floor 30 ft above its lowest ground. NOAA station records show the airport station running a median 11°F colder on the year's coldest night than Kings Canyon, over 25 years. The 3SW station, 3 miles southwest of town and also on the floor, runs a median 8°F colder over 27 years and is often the coldest of the three on the big mornings (−31°F on December 18, 2016, to the airport's −26°F and Kings Canyon's −14°F). Its yearly lows scatter more widely too, so its own 30-year number is −37°F to the airport's −33°F. That helps explain why town, closer to 3SW, plans for −36°F, while Dakota Junction, by the airport, plans for −35°F with the coldest typical winter of any named place here, −21°F.
Warmer air rides on top of the pool, and the Pine Ridge sticks up into it. That thermal belt is the biggest thing on this map. The Kings Canyon station, at 4,080 ft about 7.5 miles south-southeast of town, sits on a hillside the map puts 330 ft above its low ground. It averages a yearly low of −13°F over its 32 years on file, and on February 18, 2006 it read −16°F while the airport read −33°F. A Hungarian study of 69 clear, calm nights found a valley floor averaging 6.7°F colder than a slope 230 ft above it, and up to 13.1°F colder. Here the gap has run 16°F to 17°F on the worst mornings.
What counts is height above the nearest low ground, not above sea level. Isinglass Buttes, north of town, top out at 3,402 ft, about downtown's height, but they stand 240 ft above their low ground and plan for −31°F. Chimney Butte and Lookout Point are both 4,072 ft, but Lookout stands 440 ft above its low ground to Chimney's 310 ft and plans 3°F warmer. And Hay Springs, on open tableland at 3,855 ft just off the southeast corner, averages the same −21°F yearly low as the airport, about 560 ft below it. Flat, open tableland has nowhere to drain its cold.
None of that holds when arctic air comes in on a wind. Orchard inversions usually hold only while the wind stays under 3 to 5 mph, and a front stirs the air so higher ground runs colder. On December 22, 2022 Kings Canyon read −24°F, colder than 3SW (−22°F) and the airport (−17°F), and that's its coldest reading since 1995. The planning low draws on both kinds of night, which is part of why even the ridge plans for −28°F to −31°F. The spring layer is the calm-night pattern only.
No lake helps here; the White River is just low ground that collects cold. Town heat doesn't show for much here (downtown plans within a degree of the open floor). Snow and wind matter more. Chadron averages about 50 inches of snow a year. On the floor it stays, keeping roots warm while the air over it runs colder, but the wind strips it off the buttes and the open edges of the ridge, and Nebraska Extension says drying wind and low humidity, more than cold, limit fruit at this end of the state. Soils follow height too: the low, clay-heavy ground of the White River bottom runs cold on frost nights, while the sandy uplands drain well.
The planning low here is colder than anything the Chadron stations have recorded since 1995: town plans for −36°F, while the airport's coldest since then is −33°F (February 18, 2006) and 3SW's −32°F. Kings Canyon's 30-year number is −28°F against a coldest of −24°F. We keep that margin on purpose: 3SW read −36°F on December 21, 1990, and Hay Springs, just off the map, has been to −41°F.
Downtown Chadron, Bordeaux Creek and the north side
Downtown, with Main Street, the Dawes County Courthouse and the Commercial Historic District, sits on the floor of the Bordeaux Creek valley at about 3,380 ft. The map has Chadron at −36°F (3a), typical winter −19°F, and the city's center point, a few blocks south, at −35°F. Within 3 miles the floor and the coldest tenth of the ground both run −36°F, the benches −33°F and the warmest tenth −32°F. On a still night the cold coming down Bordeaux Creek runs right through town, and at bloom the floor reads even with the reference point or a degree colder.
On a floor lot, plant for −36°F to −37°F. Good picks: Haralson and Spartan apples (−45°F), Kindercrisp (−50°F), Zestar!® (−40°F), Kerr applecrab (−50°F), Summercrisp pear (−40°F), Toka plum (−45°F) and Evan's Bali tart cherry (−45°F). Worth a try a few feet from a south or west wall: Superior plum and Lapins sweet cherry (−35°F), 1°F to 2°F warmer than the number. A wall helps in winter but pushes bloom earlier, so expect the odd lost crop.
The south side of Chadron: the college, C-Hill and Westview
Chadron State College's south boundary runs right up against the Pine Ridge and the national forest. C-Hill, the hill south of campus with the concrete C set in 1924, is about 0.7 mile south of the city center, and its slope stands 200 ft above the floor: −32°F (3b), 4°F better than town, typical winter −16°F, and 12°F warmer than town on a still bloom night. Westview Mobile Park, on the southwest edge, sits on a toe slope 90 ft up: −34°F (3b), typical winter −17°F, 4°F warmer than town at bloom. The 2006 Spotted Tail fire stripped the pines off the escarpment south of the college, C-Hill included.
From Westview's height up to C-Hill's, plan for −32°F to −34°F. That adds Empire and Freedom apples, Superior and Italian plums (Toka pollenizes Superior), Lapins and Gold sweet cherries, Bartlett pear, Siberian C peach and Zard apricot (all −35°F), plus Westcot apricot (−45°F). Worth a try up on the C-Hill side at −32°F: Contender peach and Montmorency (−30°F). Put the earliest bloomers highest. There's fruit on campus already: the Mari Sandoz High Plains Heritage Center keeps a heritage orchard with the apple Old Jules grew on his homestead, and students there study plums, buffaloberries, chokecherries and currants.
Dakota Junction, the airport and the White River bottom
West and north of town the land keeps dropping to the White River. Dakota Junction sits right on its floor near the airport: −35°F (3b, right at the 3a line), typical winter −21°F, 2°F colder than town at bloom. The airport station's median last 28°F in spring comes May 12, a week after 3SW's. Old Jules found his wet valleys carried more blight, so on bottom ground plant the highest, best-drained spot you've got, keep fire blight magnets like Wealthy off the wettest ground, and stick with picks that have room: Trailman and Rescue applecrabs (−60°F), Brookgold plum (−50°F), honeyberries and Montana Black Currant (−50°F).
The buttes out on the plain are the warm spots: Isinglass Buttes, about 6 miles north-northeast of town, plan for −31°F and Trunk Butte, to the west, −32°F, and both run 11°F warmer than town at bloom. A slope on one, off the bottom and off the windswept top, is an orchard site.
Bordeaux, Lovers Leap and the road toward Hay Springs
Bordeaux sits about 10 miles east of Chadron on the road to Hay Springs at about 3,700 ft, more than 300 ft above downtown, and it still plans for −35°F (3a, right at the 3b line), typical winter −19°F, 2°F colder than town at bloom. It's 0 ft above its floor, at the bottom of its own valley, so the cold off the slopes around it collects right there; plant the floor list.
Climb out of the bottom and it changes fast. Lovers Leap, at 3,599 ft, stands 230 ft above its floor and plans for −33°F (3b), 12°F warmer than town at bloom. Evening Star Butte, farther east at 3,668 ft and 210 ft up, plans for −34°F and runs 11°F warmer. That's where an apricot or a European plum has a shot out this way. Past the southeast corner, Hay Springs holds the area's coldest NOAA reading in its 94-year record, −41°F on February 11, 1899.
The Pine Ridge: Kings Canyon, the buttes and Chadron State Park
South of town the ridge climbs into ponderosa pine, with cottonwoods in the canyon bottoms and plant and animal life closer to the Black Hills, about 50 miles north, than to most of Nebraska (up there, our Hot Springs, Custer and southern Black Hills map covers you). The ground at the Kings Canyon station plans for −28°F (4a), typical winter −12°F, and runs 13°F warmer than town on a bloom night. It gets 152 frost-free days to 131 and 132 at the Chadron stations.
The buttes that stand well above their floors do best. Lookout Point, 440 ft up, plans for −28°F (4a); Flannigan Butte, 460 ft up, −29°F (4a); Rattlesnake Butte −30°F (4a). Flag, Coffee Mill and Chimney buttes stand 250 to 310 ft above their low ground and plan for −31°F (3b). At bloom every one runs 12°F to 15°F warmer than town. Chadron State Park, 9 miles south along Chadron Creek, is Nebraska's oldest state park. A creek bottom like that is a drainage channel, not a thermal belt, so plant the slope above the creek, not the meadow beside it, and clear any thicket below your trees that would dam the cold.
The ridge catches late snow town misses (on May 20 to 22, 2019, parts of it got up to a foot while Chadron saw very little), deer and elk live up there, and the timber burns. But for the fruit that blooms first, it's the best ground on the map. Where it plans for −30°F or warmer (Kings Canyon, Lookout Point, Flannigan and Rattlesnake), Veteran and Contender peaches, Rainier and Stella sweet cherries, Goldrich and Harlayne apricots and the SnowCzar almond (all −30°F) clear the number.
Crawford, Whitney and Fort Robinson, just past the west edge
Crawford, Whitney and Fort Robinson sit just west of this map, so the box won't give you a number there, but our cold hardiness calculator will, and the same rules apply. Crawford sits on the White River at about 3,680 ft. Upstream, the river drops 1,100 ft through its gorge in the first 20 miles, and near Crawford the valley opens into a broad, shallow depression among rolling hills. The river bottom is where the still nights drain, and the slopes of the bluffs and low hills above it are where the thermal belt sits. Put the trees on sandy, well-drained ground rather than the gumbo clay. South in the North Platte valley, the Scottsbluff and Gering map covers you.
Spring frost and bloom around Chadron
The spring layer follows the same drainage as winter, only stronger. The floor reads even with town to 2°F colder (Dakota Junction, Bordeaux and the 3SW station 2°F colder). Westview reads 4°F warmer, and C-Hill, the buttes and the Kings Canyon hillside, all 160 ft or more above their floors, read 11°F to 15°F warmer. The FAO's frost protection manual says the cold layer on spring frost nights usually tops out 30 to 200 ft above the ground, so a couple hundred feet matters even more at bloom than in January.
NOAA station records for 1991 to 2020 agree. The median last 32°F in spring is May 16 at the airport, May 15 at 3SW and May 12 at Kings Canyon. The last 28°F, the one that kills open blossoms, comes May 12, May 5 and April 23, so the ridge gets past it about 19 days before the airport. The first fall 32°F comes September 23 to 25 in town and October 7 at Kings Canyon. The University of Vermont's orchard people use under 135 frost-free days as one mark of short-season country, and town's 131 to 132 falls under it, so a very late ripener like Siberian C peach belongs on the ridge.
Michigan State's fruit people put the line for open blossoms of nearly every tree fruit at about 28°F, but you don't need them all: only about 15 percent of apple blossoms need to set for a crop, and fully open haskap flowers take 19°F. In the bloom-time frost that hit Montana this spring (2026), our grower friends lower in the Missoula valley got hit hard while growers higher up fared much better. Nebraska Extension says late frosts often kill apricot flowers and small fruit, and that Empire is sometimes hit.
So site first; the FAO calls it "the single most important method of frost protection." Apricots, peaches, sweet cherries and European plums go on the ridge slopes or the high south edge of town, and apples, tart cherries, haskap and bush fruit can take the floor. A north- or east-facing slope holds early bloomers back (Bob Purvis's rule), and Nebraska Extension warns that south slopes push bloom ahead. Through bloom, mow under 2 inches and water a day or two before a frost night; frost cloth of 0.5, 0.9 and 1.5 oz per square yard buys about 4°F, 6°F and 8°F. In a windy freeze the warm slopes won't be warm.
What the weather records say
The coldest readings in the NOAA station files: Hay Springs −41°F (February 11, 1899), Chadron 3SW −36°F (December 21, 1990), the airport −33°F (February 18, 2006) and Kings Canyon −26°F (December 22, 1990). Published figures for the town's all-time low run colder and don't agree with each other, so we stick with the NOAA files. Average yearly lows run −21°F at Hay Springs and the airport, −20°F at 3SW and −13°F at Kings Canyon. In every big outbreak since 1990 but one, Kings Canyon ran 5°F to 17°F milder than the coldest Chadron station; the exception was the windy December 2022 front.
Chadron averages about 50 inches of snow and just under 19 inches of precipitation a year, wettest in May and June. PlantMaps puts Chadron in zone 5a (−20°F to −15°F), an average-winter zone that even reads a bit warm for the stations' −20°F to −21°F average yearly low. Our map has town at 3a, the south edge at 3b and the best of the ridge at 4a, because ours is the bad night you plan for.
What you can grow here
The Pine Ridge slopes and high buttes, −28°F to −31°F. Anything rated −35°F or colder: Lapins, Gold and Black Gold sweet cherries; Siberian C peach; Westcot, Sungold (−40°F) and Montana Mango (−35°F) apricots; Superior, Italian and Kuban Delight plums; Bartlett and Red d'Anjou pears; Ashmead's Kernel apple; Marquette grapes. Where the number is −30°F or warmer, add the −30°F list: Contender and Veteran peaches, Rainier and Stella sweet cherries, Goldrich and Harlayne apricots, Stanley plum, D'Anjou pear, Montmorency and Enterprise apple. Worth a try near Lookout Point at −28°F: Blushingstar peach (−25°F), 3°F warmer than the number.
The south edge of town, the toe slopes and the buttes on the plain, −31°F to −34°F. Everything rated −35°F or colder: Empire, Freedom and Macoun apples, Superior and Italian plums with Toka, Lapins and Gold sweet cherries, Bartlett and Seckel pears, Siberian C peach, Westcot and Zard apricots, and Meteor and Danube tart cherries. Worth a try on the warmer end of this ground: Contender peach, Rainier, Montmorency and Stanley (−30°F).
The floor: town, Bordeaux, Dakota Junction and the bottoms, −35°F to −37°F. Haralson, Spartan, Wolf River and Frostbite apples (−45°F), Kindercrisp and Wealthy (−50°F), Zestar!®, Norland and Northwest Greening (−40°F); Kerr, Centennial, Trailman and Rescue applecrabs (−50°F and colder); Krasnobokaya (−50°F), Summercrisp and Ure (−40°F) pears; Toka (−45°F), Brookred (−50°F), South Dakota and Pipestone (−40°F) plums; Evan's Bali and Meteor tart cherries and Romeo dwarf cherry (−50°F); honeyberries, Montana Black Currant, Red Lake currant, Pixwell gooseberry and Boyne raspberry (−40°F and colder), and Valiant grape (−50°F). Worth a try on the best floor ground: Empire, Superior and Lapins (−35°F), at the number to 2°F warmer.
Chokecherry, American plum, currant and buffaloberry grow wild here, and our chokecherry, Native American Plum, Golden Currant and buffaloberry have all come through −50°F, colder than anywhere on this map.
Rootstocks, pollenizers and site. Roots are the weak link: dormant apple roots are seriously hurt near 10°F while the wood takes about −40°F, and soil and snow keep them alive. At Ed Schultz's farm in Gallatin Gateway, Bud 118 rootstock has seen near −50°F with no damage, under snow. On scoured buttes and ridge tops, hold snow over the roots, mulch, and keep the soil moist into winter. Many apples need a second variety as a pollenizer, and so does Superior; our pollination maps show what goes together. Montana State University recommends a 4 to 8 percent grade where cold air won't settle, and a windbreak at least as tall as the trees, just not across the slope below them, where it dams the cold.
Water, timing and pests. A Chadron State College horticulturist reading Old Jules' notes said 11 to 15 inches of rain isn't quite enough for a good fruit crop, so use drip, the only irrigation we advise in dry country, and taper it from mid-August so trees harden off. Timing kills more trees than depth: Missoula's −7°F on October 25, 2020 killed a lot of trees rated plenty hardy on paper because they hadn't gone dormant, and Old Jules found January warm spells followed by hard freezes did most of his winter damage. Watch for fire blight (Wealthy is susceptible); Freedom and Enterprise resist cedar-apple rust and scab, and Zestar is prone to scab. Guard trunks from rabbits.
Fruit history here
The fur trade came first: James Bordeaux's trading post on Bordeaux Creek, now the site of the Museum of the Fur Trade, predates Chadron, which was founded with the railroad in 1884, and we found no record of commercial orchards around town. The big fruit name at this end of Nebraska is Jules Sandoz, "Old Jules," the "Burbank of the Sand Hills," who went into the Nebraska Hall of Agricultural Achievement in 1931. His orchards were east of here in the Sandhills. He traded letters and stock with Luther Burbank, tested more than 400 plums and kept over 60, and grew about 40 apples and 12 pears. He left branches low to shade the trunks from wind and sun, and he sited the way this map would tell you to: on north slopes or level ground, not in the valleys.
Questions people ask
What growing zone is Chadron, Nebraska?
On our map Chadron plans for −36°F, MFTC zone 3a; the south edge of town by the college and C-Hill plans for −32°F to −34°F (3b), and the Pine Ridge slopes −28°F to −31°F (4a to 3b). PlantMaps lists Chadron as zone 5a. That kind of zone is based on an average winter's coldest night, while ours is the bad night we plan for.
When is the last frost in Chadron, NE?
NOAA station records for 1991 to 2020 put the median last 32°F at May 15 to 16 at the two Chadron stations and the last 28°F at May 5 to 12. One year in ten the last 32°F comes after May 28 to May 30. Up at Kings Canyon on the Pine Ridge it's May 12 and April 23.
Is the Pine Ridge warmer than Chadron in winter?
Usually, by a lot. The Kings Canyon station, 730 to 790 ft above the Chadron stations, runs a median 8°F to 11°F milder on the year's coldest night and gets about three more frost-free weeks, because calm-night cold drains off the ridge. When arctic air comes in on a wind it flips: on December 22, 2022 Kings Canyon read −24°F to the airport's −17°F.
Can you grow peaches in Chadron or western Nebraska?
Not reliably on the floor in town: Chadron plans for −36°F, and our hardiest peach, Siberian C, has come through −35°F. On the south edge of town at −32°F to −34°F Siberian C is a good pick, and on ridge slopes that plan for −30°F or warmer, Contender and Veteran (−30°F) fit too. Nebraska Extension limits peaches to very protected sites, so give them your highest, most sheltered ground.
What apples grow best in the Nebraska Panhandle?
Nebraska Extension's list for its toughest regions includes Zestar, Haralson, Spartan, Kindercrisp, Wealthy, Empire, Enterprise and Northwestern Greening. On the floor around Chadron at −36°F, stick with the ones rated −40°F or colder: Haralson and Spartan (−45°F), Kindercrisp and Wealthy (−50°F), Zestar!® and Northwest Greening (−40°F). Empire (−35°F) wants the south edge of town, and Enterprise (−30°F) the warmest ridge slopes.
Where are the frost pockets around Chadron?
The White River bottom, the flats around the airport and Dakota Junction (the lowest named place, at 3,242 ft), the Bordeaux Creek floor through town, and the creek and canyon bottoms that drain the Pine Ridge. Bordeaux, at about 3,700 ft, still sits at the bottom of its own valley and plans for −35°F. The warm ground is the slopes well above their floor: C-Hill, the buttes and the ridge.
Warmer spots, colder spots
Here's the number to plan for at named places on the map, warmest first. Each one is the 1-in-30-year low for that spot: the cold hardiness calculator's number from the same weather stations, sharpened by our microclimate model for the ground right there. Zone is our MFTC zone, set by that one bad night, not by an average.

How this map works
Every number on this map is a 30-year planning low, the same number our cold hardiness calculator gives. It's built from NOAA station records, leans a little cold on purpose, and gets nudged a degree or two for the ground right around you. The spring frost layer runs our full terrain model, which follows cold air down the draws and into the bottoms. It's a planning number, not a promise: how long the cold lasts, wind, soil and late-winter warm spells matter too.
The physics of cold air, how the number is built, every terrain weight and the limits of the model are all on one page: how our microclimate maps work.
The weather stations behind it
These are the long-record stations in and around this map, with each one's own numbers since the winter of 1995-96. The last column is this map's 30-year number right at the station, which won't match the station exactly: it's a blend of the stations around it, the way the calculator works everywhere.
