Table S1
Chugach Metamorphic Complex Boundinage Data from locations in D3
dextral shear zones. See Sisson and Pavlis (1993) and Scharman
et al. (2011) for site locations. Averages for stretch,
quadratic elongation, and shear strain are reported. Boudin
dimensions were measured directly from outcrops at Wernicke
Glacier and Western Copper River sites. Boudin dimensions were
measured from photographs in Adobe Illustrator for the
Transition Glacier and Tana Glacier sites.
