Thirty-nine types of surficial geologic deposits and residualmaterials of Quaternary age are described and mapped in the greaterDenver area, in part of the Front Range, and in the piedmont andplains east of Denver, Boulder, and Castle Rock. Descriptionsappear in the pamphlet that accompanies the map. Landslidedeposits, colluvium, residuum, alluvium, and other deposits ormaterials are described in terms of predominant grain size, mineralor rock composition (e.g., gypsiferous, calcareous, granitic,andesitic), thickness of deposits, and other physicalcharacteristics. Origins and ages of the deposits and geologichazards related to them are noted. Many lines between geologicunits on our map were placed by generalizing...
Fifty-three types of surficial geologic deposits and residual materials of Quaternary age are described in a pamphlet and located on a map of the greater Pueblo area, in part of the Front Range, in the Wet and Sangre de Cristo Mountains, and on the plains east of Colorado Springs and Pueblo. Deposits formed by landslides, wind, and glaciers, as well as colluvium, residuum, alluvium, and others are described in terms of predominant grain size, mineral or rock composition (e.g., gypsiferous, calcareous, granitic, andesitic), thickness, and other physical characteristics. Origins and ages of the deposits and geologic hazards related to them are noted. Many lines drawn between units on our map were placed by generalizing...
This digital map shows bedding attitude symbols display overthe geographic extent of surficial deposits and rockstratigraphic units (formations) as compiled by Trimble andMachette 1973-1977 and published in 1979 (U.S. GeologicalSurvey Map I-856-H) under the Front Range Urban CorridorGeology Program. Trimble and Machette compiled their geologicmap from published geologic maps and unpublished geologicmapping having varied map unit schemes. A convenient feature ofthe compiled map is its uniform classification of geologicunits that mostly matches those of companion maps to thenorth (USGS I-855-G) and to the south (USGS I-857-F).Published as a color paper map, the Trimble and Machette mapwas intended for land-use planning...
