Lorenzo’s center stands about 4,390 ft above sea level. Within three miles the land runs from 4,320 ft to 4,440 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Ogallala Group or Formation (siltstone-mudstone, conglomerate-sandstone), from the Miocene, 5.3 to 23 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 37×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone-mudstone, conglomerate-sandstone. Age: Miocene, 5.3 to 23 million years old. About 14 mi of the line.
Sandstone, conglomerate. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 8 mi of the line.
Clay. Age: Early Oligocene to Late Oligocene, 23 to 34 million years old. About 2 mi of the line.

A raindrop that lands in Lorenzo reaches the Gulf of America by way of Lodgepole Creek, the South Platte, the Platte, the Missouri and the Mississippi: about 2,270 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 Lorenzo; river miles along the main stem, rounded.
Lorenzo has a cold semi-arid climate. Summer afternoons average 90° in July; winter nights fall to about 13° in December. About 16 inches of rain fall in a normal year.
On November 14 Lorenzo normally reaches 52° and falls to 22°. The record high is 77°, in 2025; the record low −3°, in 1959. The most rain on this date, 0.16 in, fell in 1980.
Normals 1991–2020 and records since 1948 at Sidney Municipal Airport, 6 miles northeast, 100 ft lower. NOAA, through RCC-ACIS.
