During Spring Break, 2006, Professor Barbara John led 8 students interested in the mechanics of crustal deformation processes on a tour of the highly extended southern Basin and Range. The foci of this trip were to investigate the mechanics of faulting and deformation in mid- to upper crustal regimes, and to examine the nature of normal fault contacts believed to have formed and accommodated slip at low-angle orientations (<30 degrees). A three-day canoe trip down the Colorado River took the group through the beautiful Topock Gorge, and revealed impressive geologic relationships in this highly extended region.
