Geology was compiled mainly from field mapping and photo-interpretation by D. J. Miller in 1960. Bedrock geology in the area adjoining Yakutat Bay and Russell Fiord was taken from R. S. Tarr and B. S. Butler, U.S. Geological Survey Professional Paper 64, plate 37, 1909. Geology in the vicinity of Moser Creek and Miller Creek was based on field notes of Eliot Blackwelder from 1906. This map was converted to GeMS or digitized into GeMS by Kinney Engineering, LCC., quality controlled, and then finalized by DGGS staff (Chris Wyatt). Ally M. Steinleitner implemented final database quality control and packaging. This geologic map (or report or conversion or product, etc.) was funded by the USGS National Cooperative Geologic Mapping Program under STATEMAP award number G24AC00521, 2024, and the State of Alaska General Fund.

The purpose of this report was to describe the bedrock geology of the Yakutat district and to summarize geologic features relevant to assessing petroleum potential in the Gulf of Alaska Tertiary province. It documented the volcanic unit and Yakutat group, their ages, lithologies, and metamorphic trends, and compiled results from mid-twentieth-century exploration that demonstrated the presence of subsurface Tertiary sedimentary rocks and petroleum beneath the coastal plain.
