Abstract
Ponderosa pine forests cover more than half of the timbered lands in Colorado. This forest zone occupies most of the Colorado Front Range, the easternmost range of the central Rocky Mountain system. Here ponderosa pine is found at elevations between 6,500 and 9,000 feet. Land features consist of ridges, mountain slopes, steep rocky canyons, foothills, narrow mountain valleys, and large openings or parks. Most soils originate from granites, which disintegrate readily and produce soils that erode easily when exposed. Soils derived from schist are next in extent but occupy considerably less land. Soils of sedimentary origin are minor.
