Abstract Data 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...

Crushed stone and sand and gravel are the main types of natural aggregate used in the United States. Aggregate is used in nearly all residential, commercial, and industrial building construction, and in most public works projects including roads and highways, bridges, railroad and light rail beds, airports, water and sewer systems, and tunnels. Much of the infrastructure built during the 1950s and 1960s has deteriorated to a point that requires extensive repair or replacement. All this construction requires enormous amounts of aggregate. In Colorado, for example, nearly 45 million tons of aggregate, or about 12 tons per person, were produced during 1994.
