The Dixie National Forest, with headquarters in Cedar City, Utah, occupies almost two million acres and stretches for about 170 miles across southern Utah. It straddles the divide between the Great Basin and the Colorado River.
Elevations vary from 2,800 feet near St. George, Utah to 11,322 feet at Blue Bell Knoll on Boulder Mountain. The southern rim of the Great Basin, near the Colorado River, provides spectacular scenery. Colorado River canyons are made up of many-colored cliffs and steep-walled gorges.
The Forest is divided into four geographic areas. High altitude forests in gently rolling hills characterize the Markagunt, Pansaugunt, and Aquarius Plateaus. Boulder Mountain, one of the largest high-elevation plateaus in the United States, is dotted with hundreds of small lakes 10,000 to 11,000 feet above sea level.
The Forest has many climatic extremes. Precipitation ranges from 10 inches in the lower elevations to more than 40 inches per year near Brian Head Peak. At the higher elevations, most of the annual precipitation falls as snow. Thunderstorms are common during July and August and produce heavy rains. In some areas, August is the wettest month of the year.
Temperature extremes can be impressive, with summer temperatures exceeding 100 degrees Fahrenheit near St. George and winter lows exceeding -30 degrees Fahrenheit on the plateau tops.
The vegetation of the Forest grades from sparse, desert-type plants at the lower elevations to stands of low-growing pinyon pine and juniper dominating the mid-elevations. At the higher elevations, aspen and conifers such as pine, spruce, and fir predominate.[Source]
