The <br />tops of the Rollins <br />sandstone, the Cozzette <br />Sandstone and the <br />Corcoran sandstone are <br />shown. <br />Note that the Cozzette and <br />Corcoran sandstones are <br />bounded above and below <br />by thick, dense Mancos <br />marine shale. There is a <br />tongue of Mancos shale in <br />the Getty 1-7LW well <br />separating the Rollins <br />sandstone from the <br />Cozzette sandstone. As this <br />illustration, which includes <br />the well log from a well <br />approximately 12 miles <br />away shows, this shale <br />tongue, and the character of <br />deposition of these <br />sediments, is laterally very <br />persistent. <br />Rollix SS <br />Tongue of Manors Shale <br />Coaelte Sandstone <br />Corcoran Sandstone <br />Maxus Shale <br />3 <br />
