Geologic map of the Thaumasia Quadrangle of Mars Geologic map of the Thaumasia Quadrangle of Mars

The Thaumasia quadrangle lies on the south flank of the Tharsis dome (Hord and others, 1974), a large bulge in the crust of Mars extending more than 5,000 km northward from the center of the quadrangle. The major structure imposes a generally southward slope across the entire quadrangle. Topography along the east-central border of the Thaumasia quadrangle exhibits curved scarps and...

Geology and water-yielding characteristics of rocks of the northern Powder River basin, southeastern Montana Geology and water-yielding characteristics of rocks of the northern Powder River basin, southeastern Montana

Numerous and widespread subbituminous and lignite coal deposits occur in the Powder River Basin in southeastern Montana, principally within the Fort Union Formation. Many of the coal beds are less than 250 feet (76.2 m) below land surface and are, therefore, mineable by surface methods. Individual cola beds are commonly 20-30 feet (6.1-9.1 m) thick, but may be as much as 80 feet (24 m)...
