|Location and accuracy||The occurrence is located in the N1/2 section 13, T. 2 S., R. 1 E., of the Seward Meridian. It is located at the head of Talus Bay on the north shore of Day Harbor. This is location 102 of Tysdal (1978 [MF-880-A]) and location S-187 of Jansons and others (1984). This location is accurate to within half a mile.|
Geologic descriptionThe occurrence is a shear zone several yards wide in gabbro; one sample contained 1,500 ppm chromium and 300 ppm nickel (Tysdal, 1978 [MF-880-A]). Nelson and others (1985) mapped the gabbro as part of the Resurrection Bay Ophiolite sequence of Late Cretaceous age. No other information is available in the literature.
