2.04.6 Geology Description <br />The mountainous terrain with deep canyons that flanks Grand Valley to <br />the southwest and west of Grand Junction is more complex geologically <br />than other parts adjoining the Grand Junction Area. This complexity <br />results from the Uncompahgre uplift, as is evidenced by the sharply tilted <br />landscape and varicolored rocks to the west of the Redlands. This uplift, <br />after ages of severe geologic erosion, has caused the exposure of several <br />of the upheaved geologic formations that before the uplift normally were <br />situated far below the thick, 4,000 foot, Mancos shale bed. From the top <br />downward, in respect to their former position below the Mancos shale, the <br />formations include Dakota, Morrison, Summerville, Entrada, Kayenta, <br />Chinle, and the lower pre- Cambrian. These give rise to the sandy soils of <br />the Redlands. <br />(2) Surface Mining - Not Applicable <br />Permit Application 2.04 -10 04/11 <br />
