The Wagon Mound plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
Wagon Mound’s center stands about 6,220 ft above sea level. Within three miles the land runs from 6,140 ft to 6,840 ft, a difference of 700 ft: hilly country. The highest named summit within 15 miles is Cerro Negro, about 7,720 ft, 15 miles west-northwest.
The section below crosses 13 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Unconsolidated. Age: Pleistocene to Holocene, less than 0.1 million years old. About 7 mi of the line.
Unconsolidated. Age: Pleistocene to Holocene, less than 2.6 million years old. About 4 mi of the line.
Sandstone, conglomerate-sandstone. Age: Late Triassic, 227 to 237 million years old. About 3 mi of the line.
Basalt, andesite. Age: Pliocene, 2.6 to 5.3 million years old. About 2 mi of the line.
Unconsolidated. Age: Pleistocene to Holocene, less than 0.8 million years old. About 2 mi of the line.
Arenite, shale. Age: Early Cretaceous to Late Cretaceous, 94 to 113 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 7 smaller units along the line are not listed.

A raindrop that lands in Wagon Mound reaches the Gulf of America by way of Carrizo Creek, the Canadian, the Arkansas and the Mississippi: about 1,860 river miles.
Lakes on the way: Conchas Lake, Murray Lake, Ozark Lake and Ute Reservoir.
720 miles of the trip are on the Canadian.
