Location: Christmas Creek is an approximately 10-mile-long, east tributary to the Ungalik River. The exact location of prospecting along Christmas Creek is not known; the coordinates are arbitrarily selected at the approximate midpoint of the creek. The location is accurate within 5 miles.
Geology: The headwaters of Christmas Creek drain an area underlain by graywacke, shale, conglomerate, and grit of the Cretaceous Shaktolik Group (Cass, 1959). The lower portion of Christmas Creek is underlain by Cretaceous Ungalik conglomerate. The contact between the Shaktolik Group and Ungalik conglomerate was identified on aerial photographs (Cass, 1959). Placer claims were staked during the 1900's, but Smith and Eakin (1911) report no activity on those claims as of 1909. There is no further information about placer gold on Christmas Creek.
Workings: Placer claims were staked during the 1900's, but Smith and Eakin (1911) report no activity on those claims as of 1909. There is no further information about placer gold on Christmas Creek.
Age: Quaternary.
