<br />Section 785.19 (c) Continued. <br />Unconsolidated stream-laid deposits in the Canadian River flood- <br />plain were mapped within the boundaries of the general area shown <br />on Figure 34, Kerr Hydrology General Area. Information from the <br />Preliminary Geologic Map of the Gould Quadrangle, .North Park, <br />Jackson County, Colorado (Kinney, 1970) was used together with <br />field reconnaissance to map the unconsolidated stzeam-laid deposits <br />shown on Map 5, North Park Hydrology. <br />I • <br />Unconsolidated stream-laid deposits in the mine plan and adjacent <br />area were mapped in detail by field checking the aurficial geology <br />shown on Map 6, Kerr Mine Area Geology, and digging backhoe pits to <br />determine the lithology of the stream-laid deposits. In addition, <br />the low-lying areas which contain alluvial deposits were field <br />checked to varify the existence or non-existence of stream channels <br />meeting the definition of "unconsolidated stream-laid deposits <br />holding streams" in 30 CFR 701.5. Stream-laid deposits were found <br />in the ephemeral drainages in the mine plan and adjacent area; <br />however, these drainages do not contain stream channels meeting the <br />above definition, and so the deposits in the ephemeral drainages <br />were not mapped. Unconsolidated stream-laid deposits holding <br />streams were mapped in the intermittent draws traversing the mine <br />plan and adjacent area. As shown on Map 16, the intermittent <br />drainages are Bolton Draw, Bush Draw, Williams Draw and Sudduth <br />Draw. These drainages are discussed below. <br />Bolton Draw is an intermittent stream valley which drains 6.8 <br />square miles. Stream-laid deposits were found in the lower reach <br />of the draw along a narrow floodplain approximately 500 feet wide. <br />These deposits appear as fine sand and clay at the surface, and <br />extend as a continuous deposit from the pond at the north line of <br />Section 11, TSN, R78W, to the confluence with the Canadian River in <br />Section 31, TSN, R77W. <br /> <br />785-8 <br />
