Review of Blasting Operations of Summit Brick SITE LOCATIONS & GEOLOGY, cont' 5. The Patton Clay Mine: (Permit # M-1998-067) Map 5. shows the genera] location of the Patton Clay Mine where the geology consists of the strata and clays of the Glen Eyrie Shale member of the Fountain Formation. Further, the map shows streams, roads, utilities, wells, al] dwellings with in 3000 ft., and other structures. There are no dweilings and wells exist within 3000ft. of the proposed blasting. There is extensive published geological work has mapped the Fountain Formation with the associated clays and shales throughout Fremont County. It is the Eyrie shale member which is situated stratigraphically several thousand ft. below the Dakota Group, and contains shales and clays which have brick making properties. Site specific geology indicates that strata of the Glen Eyrie striking N 30° W and dipping to the north-east, out- crop 220 ft. above an alluvial valley floor, where Wilson Creek flows. 6. The Cedarwood Clay Mine: (Permit # M-1977-317) Map 6. shows the general location of the Cedarwood Mine where the geology, again is very similar to that of the Fox mine, and consists of the strata and clays of the Glencairn Formation, Dakota Group. Further, the map shows streams, roads, utilities, wells, all dwellings with in 2000 ft., and other structures. There are no dwe[[ings or wells within 2000ft. of the proposed blasting. Extensive published geological work has mapped the Dakota Sandstone Group with the associated clays throughout this section of Pueblo County. Near the middle of the Dakota Group ties the Glencairn Farmation, which contains shales and clays which have brick making properties. Site specific geology indicates that the subject Dakota Group strikes N 10° W and dips to the north-east, existing as an un-eroded island; situated above the surrounding formations. Local wells are not producing from the Dakota Aquifer. 8
