General comments

Subject category Comment text
Deposit DEPOSIT AT MOST LIKELY PLACER SITE (SEC. 31) IS LOW GRAVEL TERRACE ON WEST SIDE OF AND UP TO 40 FT ABOVE STREAM LEVEL; SEC. 30 SITE IS ON SIMILAR TERRACE BUT ON YAMPA RIVER. SEC. 6 SITE COULD BE OLDER TERRACE REMNANT 200 FT ABOVE STREAM LEVEL. ORIGINAL SOURCE FOR AU IN WILLIAMS FORK DEPOSITS (SECS. 6, 31) WOULD BE WHITE RIVER UPLIFT; FOR THAT IN SEC. 30 SOURCE WOULD BE PARK RANGE AND ELKHEAD MTNS.
