    Description

    My purpose is twofold: to review key messages from previous speakers and to offer some concepts that may help you link recently acquired information. When Mt. Mazama erupted about 7,000 years ago, its airborne ash and pumice fell on a wide variety of existing soils. This Mazama tephra was a new parent material for soil development (fig. 1). At some locations, the original deposition was redistributed by: gravity, wind, water, plants, or animal activities, including those of humans. Soil at any specific location in the Inland West is a result of these soil-forming factors and their many possible interactions.
