This elevation creates USDA zone 4b conditions here and it supports native flora including Montana’s state flower, the bitterroot, and colorful blanketflowers that bloom in the surrounding foothills and grasslands.
Big Sky
Big Sky lies in USDA Zones 4b and 5a, and has minimum winter temperatures ranging from -25°F to -15°F (-31.7°C to -26.1°C). The varying zones result from significant elevation differences, with Mountain Village at 7,500 feet experiencing Zone 4b conditions while lower Gallatin Canyon areas at 5,900 feet reach Zone 5a.
Bozeman
Bozeman lies in USDA Zones 4b and 5a, and have minimum winter temperatures between -25°F to -15°F (-31.7°C to -26.1°C). The city’s humid continental climate and location in the fertile Gallatin Valley creates a moderate microclimate than surrounding areas, with urban heat effects contributing to the warmer 5a zone in some areas of it.
Columbus
Columbus, Montana lies in USDA Zone 4b and has minimum winter temperatures between -25°F to -20°F (-31.7°C to -28.9°C). Located along the Yellowstone River in the state’s south-central region, Columbus faces typical continental climate conditions with cold, snowy winters and limited geographic shelter from northern air masses.
Emigrant
Emigrant lies in USDA Zone 5a and has minimum winter temperatures between -20°F to -15°F (-28.9°C to -26.1°C). Situated in Paradise Valley between the Absaroka and Gallatin mountain ranges, Emigrant receives some mountain protection while maintaining proximity to Yellowstone’s moderating climatic influences.
Gallatin River Ranch
Gallatin River Ranch lies in USDA Zones 4b and 5a, and has minimum winter temperatures from -25°F to -15°F (-31.7°C to -26.1°C). The ranch’s position along the Gallatin River corridor creates climate variations, with lower elevations near the river experiencing milder Zone 5a conditions and higher areas remain in USDA Zone 4b.
Gardiner
Gardiner lies in USDA Zones 5a and 5b, and has minimum winter temperatures between -20°F to -10°F (-28.9°C to -23.3°C). Located at Yellowstone National Park’s northern entrance, Gardiner benefits from the park’s lower elevation and proximity to geothermal features, creating Montana’s warmest zone conditions in this region.
Livingston
Livingston lies in USDA Zone 5a and has minimum winter temperatures between -20°F to -15°F (-28.9°C to -26.1°C). Positioned in the Yellowstone River valley with surrounding mountains, Livingston faces moderate winter conditions than higher elevation areas while remaining exposed to continental air masses.
Manhattan
Manhattan lies in USDA Zone 4b and has minimum winter temperatures between -25°F to -20°F (-31.7°C to -28.9°C). Located in the Gallatin Valley’s agricultural heartland, Manhattan sits at moderate elevation where continental climate patterns dominate, bringing steady cold winter temperatures typical of interior Montana.
Red Lodge
Red Lodge lies in USDA Zone 5a and has minimum winter temperatures between -20°F to -15°F (-28.9°C to -26.1°C). Situated at the base of the Beartooth Mountains, Red Lodge’s valley position provides some shelter from the harshest continental air masses while maintaining enough elevation to prevent warmer zone classification.
Three Forks
Three Forks lies in USDA Zones 4b and 5a, and has minimum winter temperatures between -25°F to -15°F (-31.7°C to -26.1°C). Located at the confluence of three major rivers that form the Missouri River, Three Forks sits in a river valley setting that creates climate variations of USDA zones 4n abd 5a, with lower areas along waterways facing slightly milder conditions.
