<br />i' <br />' 5.3 Geologic/Paleontological Resources <br />The geologic strata of the proposed quarry operations are <br />Upper Cretaceous in age. A thin veneer of Holocene sediments is <br />also present, especially along stream beds. From youngest to <br />oldest, the Cretaceous strata are: Pierre Shale, Niobrara <br />' Formation, Codell Sandstone, Carlile Shale, Greenhorn Limestone, <br />Graneros Shale, South Platte Formation, Lytle Sandstone. Fossils <br />' are known from all of these formations, but most are well known <br />invertebrates. The rarest fossils are vertebrates. Recently, a <br />' few fish fossils have been found in the Niobrara Formation in the <br />quarry south of Highway 66. This suggests that fish and possibly <br />' other vertebrates may be found in the Dowe Flats area. <br />Kenneth Carpenter, Paleontologist, is presently engaged in <br />preliminary work on the paleontological resources of the project <br />' area. The scope-of-work includes a literature search and field <br />survey of the project area. Based upon the results of Mr. <br />' Carpenter's studies, further paleontological studies and guidelines <br />will be formulated. <br /> <br />1 <br /> <br />1 <br /> <br /> <br />1 <br />60 <br /> <br />
