Avalanche and Non-Avalanche Talus Slope Comparison, Colorado Front Range.

摘要

Comparison of three talus slopes in the Front Range of the Rocky Mountains in Colorado shows differences in their formative processes. Avalanche, rockfall, alluvial, and mudflow processes appear in differing proportions on the slopes. Development of slope profiles helps differentiate between slope-forming factors. Regression equations show relationships between downslope distance and boulder size and between downslope distance and slope angle. Analysis of soil samples determines percentages of snad, silt, and clay. Finally, qualitative factors prove invaluable in confirming the presence of specific slope-forming processes. (Author)
