Stratigraphic chart showing the ages of strata in the Chugach subduction complex, strata in forearc basins along the outboard margin of the Wrangellia composite terrane, and magmatic belts emplaced in the Wrangellia composite terrane (WCT) based on compilations of Trop and Ridgway (2007), Amato et al. (2013), Gehrels et al. (2009), Stevens Goddard et al. (2018), and Trop et al. (2020). Forearc basin stratigraphy is based on Matanuska Valley–­Talkeetna Mountains area; correlative strata crop out in the Chitina Valley–Wrangell Mountains (Trop et al., 2002) and Cook Inlet (LePain et al., 2013). BC—British Columbia; CMB—Coast Mountains batholith; INT—Intermontane terrane; YTT—Yukon-Tanana.
