Relative position | The above coordinates are for the approximate center of a group of five prospects in a map area about 0.5 mile (Lat 56.039-56.044) by 1.0 mile (Long 130.246-130.265) on the mountainside south of Texas Lake (Elliott and Koch, 1981, p. 13, loc. 37). The prospects are at elevations ranging from about 3200 to 4300 feet in Sections 21 and 22. The location of the prospect area is probably accurate within about a quarter of a mile. |
