In June, 1985, the USGS conducted a seismic-refraction surey in south-central Alaska as part of the Trans-Alaska Crustal Transect (TACT) program. TACT is a multi-disciplinary investigation of the deep crust of Alaska along a corridor parallel to the Trans-Alaska Oil Pipeline from Prince William Sound to Prudhoe Bay. Full size version of plates available in additional file with the report.
