Todd Creek’s center stands about 5,040 ft above sea level. Within three miles the land runs from 4,930 ft to 5,250 ft, a difference of 320 ft: rolling country. The highest named summit within 15 miles is Riley Mound, about 5,190 ft, 12 miles north-northeast.
Under the town center the state geologic map shows Denver and Arapahoe Fms (sandstone, mudstone, conglomerate), from the Late Cretaceous to Paleocene, 56 to 100 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 32×. 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, mudstone, conglomerate. Age: Late Cretaceous to Paleocene, 56 to 100 million years old. About 14 mi of the line.
Arkose, shale, mudstone. Age: Late Cretaceous to Paleocene, 56 to 100 million years old. About 7 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Gravel, unconsolidated. Age: Pleistocene, less than 0.5 million years old. About 1 mi of the line.

A raindrop that lands in Todd Creek reaches the Gulf of America by way of the South Platte, the Platte, the Missouri and the Mississippi: about 2,380 river miles.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Todd Creek; river miles along the main stem, rounded.
Todd Creek has a cold semi-arid climate. Summer afternoons average 90° in July; winter nights fall to about 16° in January. A normal year brings about 34 inches of snow; with the rain, that comes to about 14 inches of water.
On November 14 Todd Creek normally reaches 54° and falls to 26°. The record high is 81°, in 1990; the record low 0°, in 2014. The most rain on this date, 1.17 in, fell in 1994.
Normals 1991–2020 and records since 1973 at Brighton 3 SE, 3 miles southeast. NOAA, through RCC-ACIS.
