Crownpoint’s center stands about 6,980 ft above sea level. Within three miles the land runs from 6,710 ft to 7,770 ft, a difference of 1,060 ft: steep hill country. The highest named summit within 15 miles is Hosta Butte, about 8,610 ft, 7 miles south-southwest.
Under the town center the state geologic map shows Crevasse Canyon Formation (shale, sandstone), from the Late Cretaceous, 84 to 90 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 10×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mudstone, shale, sandstone. Age: Late Cretaceous, 72 to 87 million years old. About 8 mi of the line.
Shale, sandstone. Age: Late Cretaceous, 84 to 90 million years old. About 4 mi of the line.
Shale, sandstone. Age: Late Cretaceous, 84 to 90 million years old. About 3 mi of the line.
Shale. Age: Late Cretaceous, 84 to 87 million years old. About 3 mi of the line.
Sandstone. Age: Late Cretaceous, 72 to 87 million years old. About 2 mi of the line.
Shale, sandstone. Age: Late Cretaceous, 94 to 100 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 3 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Crownpoint reaches the Gulf of California by way of Kim-me-ni-oli Wash, the Chaco, the San Juan and the Colorado: about 1,210 river miles.
Lakes on the way: Lake Mead, Lake Powell, Lake Mohave and Lake Havasu.
Seldom reaches the sea. Dams and canals now take nearly all of the Colorado before its old delta in Mexico.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Crownpoint; river miles along the main stem, rounded.
