The formation consists o'f ir- <br />regular to le^ticuiar ledges of hard fine- to mediu.~-grained calcareous <br />• sandstone enclosed ir, softer arbi'_laceous fine sardsto.^.e, rrsdstone and <br />silty shale. The Gliff House Sar.;stone overlies the 1•;enefee r~ormation. <br />The i~fenefee formation is the ;aiddle and coal bearing. formation of the. <br />Alesa Verde Group. The formation has been exposed by erosion to the norti:o:est <br />and souti~ of the proposed mining area. T'.:e 15enefee consists of a complex <br />assemblace of lenticular cross-bedded sandstones, gra}•, brown and black <br />shales and coal beds. The formation is char~_cterized b-- irregular i:eddir.r <br />and rapid lateral changes in lithr;log~~. The i;enefee formation conformabi;~ <br />overlies the Foirt Loo?:out :sandstone which is the basal`orration of the <br />i~iesa Verde Group. <br />The Foint Loo}:out Sandstone is not exposed within the area of investi- <br />gation but outcrops arnro:crostel;: "our r,_'les to the north a73 unclip.
