October 2000 -23- 003-2191 • Fox Hills Sandstone The Fox Hills sandstone of Late Cretaceous age is predominantly sandstone deposited in brackish marine water. It crops out north of Deer Creek, north of Dutch Creek, and in incomplete sections between these two places. The thickness north of Deer Creek is estimated to be about 145 feet, because the lower part is not well exposed. The lower part is mostly soft olive-brown sandy shale that contains thin limy sandstone layers and cazbonaceous plant fragments. The upper part is massive soft olive-brown sandstone that contains dazk-brown hazd limy sandstone concretions as large as 4 feet in diameter. The sandstone is fine grained and locally cross-bedded. The sand grains aze principally quartz but contain some mica and aze cemented by calcium cazbonate. Cone-in-cone layers separate some of the sandstone beds in the lower part. The upper contact with the Lazamie formation is transitional and difficult to place • consistently because of poor outcrops and the lenticulaz nature of many of the beds neaz the contact. The contact is gradational between olive-brown soft Fox Hills sandstone that contains large brown sandstone concretions, and softly yellowish-gray sandstone of the Laramie. The Fox Hills formation is present under the site at a depth of about 1800 feet as seen on the Hier & Price Water Well drilled on the project site in the center of the property (see Appendix 1). Laramie Formation The Lazaznie formation of Late Cretaceous age is predominately fresh water siltstone, claystone, sandstone, and coal. The formation is covered south of Deer Creek, but may be traced northward from Deer Creek neazly to the north line of the Littleton Quadrangle by observing dumps of abandoned coal mines to the north. The dip is generally about 55° E. on the west flanks of the basin, but flattens to neazly horizontal • in the azea of the site. LW(3191(t191 SedWwmnn1000 dx Sedalia Reeycliog Center and Depository
