Summary

The glacial stratigraphy of Fort Richardson reflects deposition in glacial and glacial-marine environments during multiple retreat phases following the last glacial maximum. A preliminary model relied heavily on the glacial history off the region, mapping by the U.S. Geological Survey, and limited borehole logs. This report expands on that model and describes new subsurface data obtained from field observations and descriptions of stratigraphic exposures and core samples from 28 new boreholes between 1997 and 1998. Geophysical techniques were applied to seven of the new boreholes and 25 existing monitoring wells, augmenting surface techniques (ground resistivity and ground penetrating radar). Beneath the cantonment is a thick unconfined [...]
