Family Tree of USGS Soil Geomorphology Work in the Colorado Front Range and Adjacent Piedmont

摘要

The soil geomorphologic work of the family tree individuals was essential, as we now have as good an understanding of the Quaternary history and soils of the range and piedmont as any such transect in the world. The work included creating mapping units, estimating ages, and inferring paleoclimate. They and other USGS colleagues have extended this work across the United States, and added the soil-neotectonic relationship to the mix. Many of them are now part of the USGS teams on Geology and Environmental Change and Geologic Hazards.
