Location and accuracy This occurrence is at an elevation of about 3650 feet, on an unnamed ridge between the upper reaches of Canyon Creek and Moonlight Creek. It is about 500 feet northeast of the center of section 11, T. 14 S., R. 15 W., Fairbanks Meridian. The location is probably accurate within about 1000 feet. The occurrence corresponds to location 101 of Thornsberry, McKee, and Salisbury (1984, fig. K-8).
