|Location and accuracy||This occurrence is at an elevation of about 2,900 feet on upper Tributary Creek. It is in the NW1/4 section 18, T. 7 N., R. 1 W., of the Seward Meridian. This is location 26 of MacKevett and Holloway (1977), location 38 of Cobb and Tysdal (1980), and location S-274 of Jansons and others (1984). This location is accurate to within a quarter of a mile.|
Geologic descriptionThe occurrence consists of quartz veins that heal fractures in a felsic dike that cuts slate and sandstone of the Valdez Group of Late Cretaceous age (Tysdal, 1978 [MF-880-A]). The quartz contains little gold or other ore minerals.
