|---|---|
| Relative position | The occurrence is about 4.2 miles northwest of Mt. Marchainville on a ridge southeast of upper Finger Glacier at an elevation of about 6000 feet. The location is estimated from the location of sample number 44 of Rossman (1963). It is approximately correct based on the 6000-foot elevation; by latitude and longitude, the location is in the adjacent B-4 quadrangle. It is probably accurate to about 0.25 mile. The location in Kimball and others (1978) is uncertain. |
