Maverick Mountain’s center stands about 6,590 ft above sea level. Within three miles the land runs from 6,430 ft to 8,580 ft, a difference of 2,150 ft: mountain country. The highest named summit within 15 miles is Torrey Mountain, about 11,080 ft, 7 miles east-northeast.
Under the town center the state geologic map shows Gravel, from the Pleistocene to Holocene, less than 1.8 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 5×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granitic. Age: Cretaceous, 66 to 145 million years old. About 10 mi of the line.
Metasiltstone, argillite, quartzite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 8 mi of the line.
Age: Pleistocene to Holocene, less than 1.8 million years old. About 3 mi of the line.
Quartzite, argillite, metasiltstone. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.
Dolostone, sandstone, limestone. Age: Early Pennsylvanian to Permian, 252 to 324 million years old. About 1 mi of the line.
Siltstone, sandstone, shale. Age: Early Triassic to Early Cretaceous, 100 to 252 million years old. About 0.4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Maverick Mountain reaches the Gulf of America by way of Grasshopper Creek, the Beaverhead, the Jefferson, the Missouri and the Mississippi: about 3,660 river miles.
Lakes on the way: Lake Oahe, Lake Sakakawea, Lake Fort Peck and Lake Sharpe.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Maverick Mountain; river miles along the main stem, rounded.
