Leadville North’s center stands about 10,010 ft above sea level. Within three miles the land runs from 9,630 ft to 11,080 ft, a difference of 1,450 ft: steep hill country. The highest named summit within 15 miles is Mount Elbert, about 14,370 ft, 12 miles southwest.
Under the town center the state geologic map shows Older gravels and alluviums (gravel, unconsolidated), from the Pleistocene, 0.2 to 1.6 million years old.
The section below crosses 10 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.
Unconsolidated. Age: Pleistocene, less than 0.5 million years old. About 5 mi of the line.
Arkose, conglomerate, shale. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Alkali-feldspar-granite, granite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.
Biotite-gneiss, schist, migmatite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 3 mi of the line.
Granitic, dioritic. Age: Late Cretaceous to Middle Eocene, 40 to 72 million years old. About 3 mi of the line.
Gravel, unconsolidated. Age: Pleistocene, 0.2 to 1.6 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. 4 smaller units along the line are not listed.

A raindrop that lands in Leadville North reaches the Gulf of America by way of the Arkansas and the Mississippi: about 2,020 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
1,130 miles of the trip are on the Arkansas.

Leadville North has a subarctic climate. Summer afternoons average 71° in July; winter nights fall to about 5° in January. A normal year brings about 157 inches of snow; with the rain, that comes to about 14 inches of water.
On November 14 Leadville North normally reaches 38° and falls to 13°. The record high is 63°, in 1999; the record low −12°, in 2000. The most rain on this date, 0.25 in, fell in 2006.
