Outcrop

Outcrop 2008 Personal Statement 25 pairs of shoes in polyester resin approximately 4′ x 8′ accompanied by annotated stratigraphic section and enlarged thin sections Geologists often create stratigraphic sections, in order to describe the rock history in an area. These sections sequentially show rock units and describe their contacts, erodibility, and depositional history. Additionally, thin Outcrop

Bedforms and Cross-Bedding in Animation

I spent two years working as a Geologist at the USGS in Santa Cruz, CA.  Bedforms and Cross-Bedding in Animation by David M. Rubin and myself is a college-level textbook on sediment transport processes.  It’s available for purchase here or you can play with the online, interactive exploration tool via the USGS Bedform Sedimentology Site.

Subglacial environment inferred from bedrock-coating siltskins

The landscape revealed by retreating glaciers provides evidence, much of it ephemeral, for subglacial processes that are difficult to observe directly. Glaciers that thin over rough bedrock surfaces continue to slide by regelation as adjacent subsurface cavity systems develop and enlarge. Subglacial deposits, including the cemented coatings we describe here, provide insight into subglacial conditions.
