Summit Park’s center stands about 6,910 ft above sea level. Within three miles the land runs from 6,220 ft to 8,330 ft, a difference of 2,110 ft: mountain country. The highest named summit within 15 miles is Twin Peaks, about 11,430 ft, 14 miles south.
Under the town center the state geologic map shows Stump and Preuss Sandstones and Twin Creek Limestone (limestone, siltstone-mudstone), from the Middle Jurassic to Late Jurassic, 145 to 175 million years old.
The section below crosses 16 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 4×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Andesite. Age: Late Eocene to Oligocene, 23 to 38 million years old. About 4 mi of the line.
Siltstone-mudstone, limestone. Age: Early Triassic, 247 to 252 million years old. About 3 mi of the line.
Unconsolidated. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Sandstone, shale. Age: Late Cretaceous, 87 to 94 million years old. About 2 mi of the line.
Limestone, siltstone-mudstone. Age: Middle Jurassic to Late Jurassic, 145 to 175 million years old. About 2 mi of the line.
Sandstone, mudstone. Age: Late Cretaceous to Late 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. 10 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 Summit Park reaches Great Salt Lake by way of East Canyon Creek and the Weber: about 80 river miles. Great Salt 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 Summit Park; river miles along the main stem, rounded.
Summit Park has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 16° in January. About 22 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1992 at Park City, 8 miles southeast. NOAA, through RCC-ACIS.
