Relative position | This occurrence consists of a locally mineralized fault or shear zone which can be traced for more than 4000-feet. The fault crosses the ridge about 0.2 mile southeast of Mt. Parker at an elevation of about 2900 feet. The coordinates, accurate within 0.1 mile, mark the point where the vein-fault crosses the ridge south of Mt. Parker. The fault continues southwesterly to Lamplugh Glacier and northeasterly into Ptarmigan Creek. Rossman (1959, B 1058-B, pl. 4, p. 55-56) reported two hydrothermally altered segments in the vein-fault, one to the northeast in Ptarmigan Creek; the second is about 2000 feet southwest of the ridge and 1000 feet east of Lamplugh Glacier. |

Deposit | Model Name = Low-sulfide gold-quartz vein (Cox and Singer, 1986; model 36a). |
Deposit | Other Comments = the occurrence is of interest because of the strength and continuous nature of the vein-fault structure. Possibly, gold-bearing veins could occur in subsidiary tensional structures or at vein intersections. Rossman's main map (B 1058-B) suggests that the northeast vein-fault will intersect the projection of the northwest striking Ptarmigan Creek fault under cover in Ptarmigan Creek basin. (The Ptarmigan Creek fault appears to be the fundamental control of the Highland Chief prospect--MF030) No near term exploration is expected because the occurrence is in Glacier Bay National Park and Preserve. |
