Description :
In this study, soil and geomorphic properties related to landslide occurence were studied at 18 landslides in the Bridger-Teton National Forest (BTNF). Landslides were categorized as active or inactive based on geomorphic features. Landslide soil characteristics including texture, shrink-swell potential, clay mineralogy, and horizonation were compared on active and inactive landslides. This study shows that soil characteristics and slope geomorphic properties may be useful for assessing landslide frequency. The results support a hypothesis that landslide occurence in the BTNF is related to weathering of soil and unconsolidated material, which affects clay mineralogy.
