The Toyei 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.
Toyei’s center stands about 6,540 ft above sea level. Within three miles the land runs from 6,210 ft to 6,660 ft, a difference of 450 ft: hilly country. The highest named summit within 15 miles is Balakai Point, about 7,440 ft, 12 miles north-northeast.
Under the town center the state geologic map shows Pliocene to middle Miocene deposits (conglomerate, sandstone), from the Early Miocene to Pleistocene, 2 to 16 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 14×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Conglomerate, sandstone. Age: Early Miocene to Pleistocene, 2 to 16 million years old. About 14 mi of the line.
Sandstone, shale. Age: Late Cretaceous, 88 to 97 million years old. About 9 mi of the line.
Sandstone, shale, coal. Age: Late Cretaceous, 84 to 88 million years old. About 0.7 mi of the line.

A raindrop that lands in Toyei reaches the Gulf of California by way of Pueblo Colorado Wash, Cottonwood Wash, the Little Colorado and the Colorado: about 1,010 river miles.
Lakes on the way: Lake Mead, Lake Mohave and Lake Havasu.
290 miles of the trip are on the Colorado.
Often dry. About 30% of the way is mapped as streams that run only after rain or snowmelt; the water makes the whole trip in floods.
