cabin in <strong>the</strong> NE 1 / 4 <strong>of</strong> Section 9. This area consists <strong>of</strong> Quaternary alluvial fan (Qfy) and<br />

landslide (Qfol) deposits derived from Bull Lake and Pinedale tills. Consequently,<br />

Crawford’s (1913) placer locality may be a misplotted location <strong>of</strong> <strong>the</strong> upper Placer Creek<br />

workings.<br />

Examination <strong>of</strong> <strong>the</strong> Bureau <strong>of</strong> Land Management LR2000 unpatented mining<br />

claim records indicate <strong>the</strong> presence <strong>of</strong> recent extensive placer mining claims that covered<br />

<strong>the</strong> nor<strong>the</strong>ast part <strong>of</strong> <strong>the</strong> <strong>Maysville</strong> quadrangle. The Valley View placer claim block was<br />

located in 1965 and covered <strong>the</strong> area from <strong>the</strong> range front on <strong>the</strong> west and extending east<br />

<strong>of</strong> <strong>the</strong> eastern quadrangle boundary, and from <strong>the</strong> South Arkansas River in <strong>the</strong> south and<br />

extending north <strong>of</strong> <strong>the</strong> nor<strong>the</strong>rn quadrangle boundary. Many <strong>of</strong> <strong>the</strong> Valley View placer<br />

claims were abandoned in 1992 and 1994. A smaller placer claim block was maintained<br />

in <strong>the</strong> area <strong>of</strong> Sections 13, 14, 15, 21, 22, 23, 24, 25, 26 and 27 (T49N, R7E) and was<br />

finally abandoned in 2002. Ano<strong>the</strong>r large block <strong>of</strong> placer claims (ALKE claims) were<br />

located and abandoned in 1996 in <strong>the</strong> same area as <strong>the</strong> Valley View claims. A new<br />

Valley View claim block was located in 2006 in Sections 23, 24, 25 and 26 indicating<br />

continued interest in <strong>the</strong> placer potential <strong>of</strong> this area. One placer claim (Early Fall claim)<br />

was located in 1979 in Willow Creek near <strong>the</strong> Bon Ton mine area but was abandoned in<br />

1991.<br />

Parker (1974) briefly described two placer mining areas along Placer Creek<br />

(Sections 14 and 15, T50N, R7E) and at <strong>the</strong> intersection <strong>of</strong> Placer Creek and Blank Gulch<br />

(Section 26). He stated that little is known <strong>of</strong> <strong>the</strong> history <strong>of</strong> <strong>the</strong>se placers but mentioned<br />

that William Blank was reported to have produced $30,000 in gold from <strong>the</strong> “upper<br />

placers.” He also mentioned that Golden Fleece Placer Company operated a small<br />

mechanized plant in 1946 and Geo-Resources Exploration, Inc. was conducting placer<br />

exploration in 1959 and 1960.<br />

PLACER DEPOSITS – Two areas <strong>of</strong> minor placer workings have been previously<br />

identified on <strong>the</strong> piedmont surface in <strong>the</strong> central part <strong>of</strong> <strong>the</strong> <strong>Maysville</strong> quadrangle (Parker,<br />

1974; and Scott and o<strong>the</strong>rs, 1975). They were described by Parker (1974) but little is<br />

known about <strong>the</strong>ir history. The largest placer workings are up to 80 ft wide for 870 ft<br />

along Placer Creek in NE 1 / 4 and SE 1 / 4 , Section 15, T50N, R7E. This area is near <strong>the</strong><br />
