Figure 2. Map showing the interpreted lake-floor geology. Four units were mapped: outcrops of Tertiary and older rocks, Quaternary alluvial deposits, thick post-impoundment sediment deposits, and thin post-impoundment sediment deposits. These are represented in the map as rock, alluvial deposits, thick sediment, and thin sediment, respectively. Click on figure for larger image.
