GEOMORPHIC MAP OF THE NORTHERN AND NORTHEASTERN MARGINSOF OWENS (DRY) LAKE, CALIFORNIA
By
Steven N. Bacon and Nicholas Lancaster
2012
Division of Earth & Ecosystem Sciences
Geomorphology mapped by Steven Bacon, P.G., C.E.G., and fieldchecked by Nicholas Lancaster, Ph.D. and Scott Stine, Ph.D.
Geomorphic map created at a fixed scale of 1:4000 using 0.5 to 1.0meter resolution spectral imagery and aerial photography acquiredin 2006, 2008, 2009, and 2010. Age of shorelines from Bacon et al.(2006) and unpublished data from S. Stine. Age constraints forgeomorphic units are from cross-cutting relations with identified anddated shorelines.
