Southeast Utah is part of the Colorado Plateau, a "high desert" region that experiences wide temperature fluctuations, sometimes over 40 degrees in a single day. The temperate (and most popular) seasons are spring (April through May) and fall (mid-September through October), when daytime highs average 60 to 80 F and lows average 30 to 50 F.
Summer temperatures often exceed 100 F, making strenuous exercise difficult. Late summer monsoon season brings violent storm cells which often cause flash floods.
Winters are cold, with highs averaging 30 to 50 F, and lows averaging 0 to 20 F. Though large snowfalls are uncommon (except in nearby mountains), even small amounts of snow or ice can make local trails and roads impassable.
Local weather conditions and forecasts are available by phone at (801) 524-5133 (recorded information), and on the Web at www.wrh.noaa.gov/slc.

Did You Know?
In the late 1800s, John Wesley Wolfe, a disabled Civil War veteran, and his son, Fred, built a homestead in what is now Arches National Park. A weathered log cabin, root cellar, and corral remain as evidence of the primitive ranch they operated for more than 10 years.
