Geographic coordinates

Geographic coordinates: -163.93338, 65.56934 (WGS84)
Relative position Hopkins (1963) discribes three exposures of diatomite in the upper valley of Andesite Creek, the northeasternmost exposure being due south of Lava Lake. The terminal parts of Lost Jim lava flow cover parts of the diatomite deposit. This location is approximate, probably within 1 mile.

Comments on the geologic information

  • Geologic Description = Diatomite was deposited in a former lake formed when a Quaternary lava flow dammed Andesite Creek. The diatomite, as observed in three areas of exposure by Hopkins (1963,) is progressively more contaminated with darker-colored organic material to the southwest. The northeasternmost exposure is nearly pure diatomite covering an area of at least 2,500 feet by 1,000 feet. Diatomitet thicknesses of 4 to 10 feet have been observed in stream and lake banks and the base is not exposed. These diatomaceous lake deposits are locally overlain by terminal parts of the Holocene Lost Jim lava flow (Hopkins, 1963).
