| Relative position | Carnes (1976, locality 4) defines this placer prospect as covering approximately a four and one-half mile stretch along the Kahiltna River centered at about the middle of the boundary between Sections 21 and 16 in T. 22., R. 18 W. (Cobb, 1972, MF 385, locality 7 and U.S. Bureau of Mines 1973, localities 22, 39, and 59). This site is on upstream extention of the placer site along the same river described in ARDF TY028. |
