Black Hat’s center stands about 7,020 ft above sea level. Within three miles the land runs from 6,660 ft to 7,270 ft, a difference of 610 ft: hilly country. The highest named summit within 15 miles is Piney Hill, about 8,120 ft, 15 miles northwest.
Under the town center the state geologic map shows Crevasse Canyon Formation (shale, sandstone), from the Late Cretaceous, 84 to 90 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, sandstone. Age: Late Cretaceous, 84 to 90 million years old. About 21 mi of the line.
Sandstone. Age: Late Cretaceous, 90 to 94 million years old. About 3 mi of the line.

A raindrop that lands in Black Hat reaches the Gulf of California by way of the Puerco, the Little Colorado and the Colorado: about 1,070 river miles.
Lakes on the way: Lake Mead, Lake Mohave and Lake Havasu.
290 miles of the trip are on the Colorado.
Often dry. About 30% of the way is mapped as streams that run only after rain or snowmelt; the water makes the whole trip in floods.

Black Hat has a cold semi-arid climate. Summer afternoons average 89° in July; winter nights fall to about 14° in January. A normal year brings about 34 inches of snow; with the rain, that comes to about 11 inches of water.
On November 14 Black Hat normally reaches 56° and falls to 20°. The record high is 73°, in 1999; the record low 4°, in 2000. The most rain on this date, 0.44 in, fell in 1997.
Normals 1991–2020 and records since 1973 at Gallup Municipal Airport, 13 miles southeast, 560 ft lower. NOAA, through RCC-ACIS.
