Abstract

The primary purpose of this report is to provide drafted field logs of exploratory trenches excavated across the Berryessa Fault section of the northern Green Valley Fault (Lienkaemper, 2012; Lienkaemper and others, 2013) in 2011 and 2012 that show evidence for at least one surface-rupturing earthquake in the past few centuries. The site location and site detail are shown on sheet 1. The trench logs are shown on sheets 1, 2, 3 and 4. We also provide radiocarbon ages used for chronological modeling of the earthquake history and a field description of a soil profile in one trench. A formal report based on these logs and data is in preparation.
