The Redmond 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.
Redmond’s center stands about 5,110 ft above sea level. Within three miles the land runs from 5,090 ft to 5,620 ft, a difference of 530 ft: hilly country. The highest named summit within 15 miles is Jacks Peak, about 10,060 ft, 15 miles west.
Under the town center the state geologic map shows Older alluvial deposits (coarse-detrital), from the Quaternary, less than 2.6 million years old.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 7×. 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: Quaternary, less than 2.6 million years old. About 7 mi of the line.
Limestone. Age: Late Paleocene to Early Eocene, 48 to 59 million years old. About 3 mi of the line.
Shale, marlstone. Age: Early Eocene to Late Eocene, 34 to 56 million years old. About 3 mi of the line.
Unconsolidated. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 3 mi of the line.
Limestone, mixed-clastic. Age: Late Paleocene to Early Eocene, 48 to 59 million years old. About 2 mi of the line.
Siltstone-mudstone. Age: Late Cretaceous to Paleocene, 56 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. 6 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 Redmond reaches Sevier Lake by way of the Sevier: about 200 river miles. Sevier Lake has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Redmond; river miles along the main stem, rounded.
