Introduction

The Auxiliary Material for this contribution contains several pieces of additional information 
that pertain to the details of the regional tectonics of the northern eastern California shear 
zone and cosmogenic nuclide geochronology methods.  Further descriptions of the kinematics and 
slips rates of individual faults (Owens Valley fault zone, Panamint Valley fault zone, Ash Hill 
fault zone, Hunter Mountain fault zone, Stateline fault zone, and dip-slip transfer faults) in 
the northern eastern California shear zone are given in Text S1. Text S2 provides information 
on cosmogenic nuclide geochronology sample processing and age calculations.  The CHLOE depth 
profile model is described in Text S3. Chemical data for the Chlorine-36 geochronology depth 
profile samples are reported in Table S1. Table S2 gives soil descriptions for each of the depth 
profile sample locations.
