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 Age of shorelines from Bacon et al.(2006) and unpublished data from S. Stine.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.

Geographic coordinate system WGS 1984
