Fig. 11. Horton Creek outcrop. (A) The Horton Creek fault and fault traces interpreted on the photo. (B) Exposed fault contact between older lacustrine deposits and younger air-fall sequences of the Bishop Tuff. (C) Nonwelded ignimbrite and air fall deposits about 30 m north of the fault trace. Pumice fragments and glass have an average grain size of 0.9 to 1.9 m or coarse to very coarse sand particle size, show inverse grading, and are overall very poorly sorted, angular grains.
