2 - 55 <br />• The Hunter Canyon Formation, which is locally the uppermost unit of the Mesa Verde Group <br />conformably overlies the Mount Garfield Formation. The exact contact is difficult to precisely <br />delineate throughout the permit area. Visually and lithologically the two formations are very <br />similar, but the Hunter Canyon Formation includes no coal bearing zones. This formation is <br />assumed to represent the sequence of beds which would form upland from the coal forming <br />delta paleoenvironment of the Mount Garfield Formation. <br />Unconformably overlying the Hunter Canyon formation is the Paleocene Wasatch Formation, <br />which consists of buff to white, medium to coarse grained, occasionally massive cliff forming <br />sandstones and a few interbedded shales. <br />The Quaternary alluvium beds occupy the valley floors and consist of unconsolidated clay <br />• and sand. The colluvium features result from the landsliding of oversteepened slopes. These <br />features can sign~canUy impact the continuity of the coal seam. <br />~J <br />A~ Volume 1 4-29-96 <br />
