Part II of the Sixteenth Annual Report of the U.S. Geological Survey concerns economic geology and was published under the direction of Charles Walcott . This volume contains Cross and Penrose's "Geology and Mining Industries of the Cripple Creek District, Colorado" and J. Edward Spurr's report on "Economic Geology of the Mercur Mining District, Utah" among others. The complete volume contains 40 plates, 65 in-text illustrations, and the following two folding maps housed in a rear pocket:

Colorado Cripple Creek Special Map (16.1 x 19.6"). This striking topographic map shows the mining town (and former ghost town) Cripple Creek and its surroundings in what is today Teller County. Several mountains, gulches, and hills are named, and a few towns appear in grid-like plans, including Victor and Cripple Creek itself. A legend to the right of the map explains the corresponding rock type for each color and pattern combination on the map. The map is also freckled with several small stars that represent various gold mines and prospects.

United States Showing Disposition of Lands (28.2 x 17.5"). This attractive map of the United States is color-coded to show the status of federal lands, including a large swath of disposed lands in the center of the country and along the west coast. Other types include vacant public lands, forest reservations, Indian lands, railroad grants, and land not owned by the federal government (former colonies and Texas). Compiled by Frederick Haynes Newell, who would later become the first director of the United States Bureau of Reclamation in 1902.
