Bulletin 955-D. <br />-Aerial map from 1979 before mine permitting <br />The Alma Group of placer claims are located for over three miles along the South Platte River and <br />have been mined since 1868. The gold bearing gravels located in this azea aze primarily glacial in <br />origin. These gravel deposits are judged to be the lateral and possibly some terminal moraines left by <br />the last retreating glaciers appear to be largely unchanged by subsequent erosion actions east of the <br />river. West of [he river, where stream action and man have destroyed the distinctive structures of the <br />gravel deposits, sands in the Alma Mining District are largely granitic gaeisses with a small <br />percentage of sedimentary, volcanic and metamorphic materials. The sizing of the gravels is <br />estimated in Table 1. <br />TABLE 1 <br />Sizing Estimates of Gravels on the Alma Group Claims <br />Plus 24 inch rocks- few above 36 inches 10% <br />Plus 6 inch rocks minus 24 inch rocks 10% <br />Atma Placer 7/03 65 <br />
