“…Numerous studies using lowtemperature thermochronology have focused on exhumational patterns across major fault systems associated with fl at-slab subduction in southern Alaska, including studies in the Alaska Range (e.g., Fitzgerald et al, 1995;Haeussler et al, 2008Haeussler et al, , 2011Benowitz et al, 2011Benowitz et al, , 2012Benowitz et al, , 2013, Chugach Mountains (Little and Naeser , 1989;Buscher et al, 2008;Arkle et al, 2013), and Saint Elias Mountains (e.g., Berger et al, 2008aBerger et al, , 2008bBerger and Spotila, 2008;Meigs et al, 2008;Enkelmann et al, 2008Enkelmann et al, , 2009Spotila and Berger, 2010). Some of these studies detected loci of rapid exhumation, particularly in the Saint Elias and western Chugach Mountains, which may be the result of crustalscale lithologic backstops to upper crustal rock deformation above the subducting Yakutat microplate.…”
