Marysvale’s center stands about 5,870 ft above sea level. Within three miles the land runs from 5,820 ft to 7,590 ft, a difference of 1,770 ft: steep hill country. The highest named summit within 15 miles is Delano Peak, about 12,140 ft, 9 miles southwest.
Under the town center the state geologic map shows Alluvium and colluvium (unconsolidated), from the Quaternary, less than 2.6 million years old.
The section below crosses 5 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.
Felsic-volcanic. Age: Late Oligocene to Middle Miocene, 12 to 28 million years old. About 16 mi of the line.
Unconsolidated. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.
Quartz-monzonite. Age: Early Oligocene to Early Miocene, 16 to 34 million years old. About 1 mi of the line.
Arenite, sandstone-mudstone. Age: Early Jurassic to Middle Jurassic, 164 to 202 million years old. About 0.3 mi of the line.

A raindrop that lands in Marysvale reaches Sevier Lake by way of Pine Creek and the Sevier: about 280 river miles. Sevier Lake has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Marysvale; river miles along the main stem, rounded.
Marysvale has a cold semi-arid climate. Summer afternoons average 90° in July; winter nights fall to about 12° in January. A normal year brings about 45 inches of snow; with the rain, that comes to about 12 inches of water.
On November 14 Marysvale normally reaches 53° and falls to 20°. The record high is 70°, in 1990; the record low 2°, in 2000. The most rain on this date, 0.14 in, fell in 2010.
