Map of the southern Sierra Nevada and San Joaquin Basin, California, showing major late Cenozoic faults as well as important structural and geomorphic features. The location of the Kern River watershed is outlined on the inset map of California and overlaid in white on the 30 m shaded relief of the regional map. The mouth of the Kern River (white square) is located at the transition between the southern Sierra Nevada and the San Joaquin Basin. Prominent knickpoints along the Kern River are shown as white circles. The location of Breckenridge Mountain (BkM), the Greenhorn Mountains, and the Piute Mountains are shown. The Kern arch region (tan), low-relief upland surface (green), and exhumed early Tertiary nonconformity surface (green patterned) are after Saleeby et al. (2016). Major fault systems that bound the southern Sierra Nevada are modified from the U.S. Geological Survey Quaternary faults database (U.S. Geological Survey and California Geological Survey, 2006). Faults of the southern Sierra Nevada fault system are after Mahéo et al. (2009) and Saleeby et al. (2016). The solid black lines represent faults with certain locations while dashed black lines represent faults with estimated or inferred locations. The thick red line denotes the present position of the delamination hinge trace that has been migrating northward since <1 Ma (after Saleeby et al., 2012, 2013).
