The for.•iation consists of ir- <br />reEvlar to lenticular ledges of hard fine- to median-grained calcareous <br />sandstone enclosed in softer ar~i'_laceous fine sar.dsLone, rwdstone and <br />silty shale. The Miff liousc ;ian;stone overlies the !•:e~e_*ee rormation. <br />The i•fenefee ?ormation is the -`_idle and coal bearing formation of the <br />!•:esa Verde Group.
