Geologic map of the Colombo Quadrangle of the Moon
D. P. Elston
1972, IMAP 714
Relative ages of structures and geologic units have been determined from intersection and apparent overlap relations and from morphologic freshness reflecting degree of preservation. The fivefold crater-age sequence is based on the classification of Shoemaker and Hackman (1962<span...

1972, IMAP 591-F
This map shows streamflow measured in acre-feet (1 acre-foot Is the amount of water that would cover an area of one acre to a depth of one foot – 43,560 cubic feet or about 326,700 gallons). Streamflow is measured and recorded by the U.S. Geological Survey at gaging stations located...

Significance of ground-water chemistry in performance of North Sahara Tube wells in Algeria and Tunisia
Frank Eldridge Clarke, Blair F. Jones
1972, Water Supply Paper 1757-M
Nine ground-water samples from the principal shallow and deep North Sahara aquifers of Algeria and Tunisia were examined to determine the relation of their chemical composition to corrosion and mineral encrustation thought to be contributing to observed decline in well capacities within a UNESCO/UNDP Special Fund Project area. Although the...
Map Showing Areas Containing Swelling Clay in the Morrison Quadrangle, Jefferson County, Colorado
Glenn R. Scott
1972, IMAP 790-C
Formations that contain clays having swelling pressures higher than 2,500 pounds per square foot (as measured by the Potential Volume Change meter) are listed in order of decreasing swelling pressure: Denver Formation, Pierre Shale, Laramie Formation, Green Mountain Conglomerate, Fox Hills Sandstone, and Arapahoe Formation. Some landslides derived from these...
