Hobble Creek’s center stands about 5,320 ft above sea level. Within three miles the land runs from 5,070 ft to 8,650 ft, a difference of 3,580 ft: mountain country. The highest named summit within 15 miles is Provo Peak, about 10,970 ft, 5 miles northwest.
The section below crosses 15 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 3×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Carboniferous to Permian, 273 to 324 million years old. About 8 mi of the line.
Limestone. Age: Early Mississippian to Late Mississippian, 324 to 359 million years old. About 5 mi of the line.
Conglomerate, sandstone. Age: Late Cretaceous to Paleocene, 56 to 84 million years old. About 3 mi of the line.
Siltstone-mudstone, sandstone. Age: Late Cretaceous to Early Eocene, 48 to 84 million years old. About 2 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 1 mi of the line.
Latite, quartz-latite. Age: Late Eocene to Oligocene, 23 to 38 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. 9 smaller units along the line are not listed.

A raindrop that lands in Hobble Creek reaches Great Salt Lake by way of Left Fork Hobble Creek, Hobble Creek and the Jordan: about 85 river miles. Great Salt Lake has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.
Lake on the way: Utah Lake.
50 miles of the trip are on the Jordan.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hobble Creek; river miles along the main stem, rounded.
Hobble Creek has a dry-summer warm-summer continental climate. Summer afternoons average 86° in July; winter nights fall to about 13° in January. A normal year brings about 74 inches of snow; with the rain, that comes to about 22 inches of water.
On November 14 Hobble Creek normally reaches 49° and falls to 23°. The record high is 70°, in 1990; the record low 2°, in 1959. The most rain on this date, 1.63 in, fell in 1955.
Normals 1991–2020 and records since 1939 at Deer Creek Dam, 15 miles north. NOAA, through RCC-ACIS.
