... and distributions of drill holes and surface structural data. Modelling has focused on prominent anomalies related to relatively strong magnetizations within the Creston Formation and Moyie sills. Models of the western flank of the anticline indicate the Creston Formation forms the bulk of a westward-thickening...

The Sangre de Cristo Formation contains (1) a sandstone facies deposited on the distal surfaces of alluvial fans, and (2) a conglomerate facies (Crestone Conglomerate Member) deposited on the proximal surfaces of alluvial fans. The sandstone facies consists of fining-upward cycles of red conglomeratic...
