This report, and the 50,000-scale map that accompanies it (Plates 1, 2 and 3) summarize the geology of the Upper Cretaceous through Eocene strata in this developing metropolitan corridor. These strata are the foundations of this development, and much its water source.
Plates 1,2 and 3, in pocket. The area summarized in this report is located in the southern part of the Colorado Piedmont sections of the Great Plains. The northern part is mostly located in the Cherry Creek and Plum Creek drainage basins, which are tributary to the South Platte River (figure 2). Minor parts of the Box Elder Creek drainage basin are included along the northeastern edge. The southern part of the area is located in the drainage basins of Monument Creek, Jimmy Camp, and Black Squirrel Creeks, tributaries of the Arkansas River. 53 pages. 39 figures. 3 plates (1:50,000).
