Painted Canyon, Southern San Andreas Fault

Welcome Guest   ( Sign In )
OT Dataspace
The Painted Canyon site is located in the Mecca Hills adjacent to the Southern San Andreas Fault. The site records plate-boundary transpression in a set of folds and faults. We imaged a fold along a canyon wall in Painted Canyon. We collected this dataset to be part of an undergraduate or graduate-level structural geology remote field class exercise available here: In this exercise, students measure and analyze the fold using the point cloud, CloudCompare (, and Stereonet ( The students put their measurements in terms of the kinematics of the San Andreas Fault.
