The Hobart plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
92° on Nov. 17, 2017, the hottest reading for this week of the year since 1910. Next is 86° in 2021.
Hobart’s center stands about 1,550 ft above sea level. Within three miles the land runs from 1,490 ft to 1,610 ft, a difference of 120 ft: gently rolling country. The highest named summit within 15 miles is Soldiers Peak, about 2,330 ft, 15 miles southwest.
Under the town center the state geologic map shows Hennessey Group (shale), from the Permian, 252 to 299 million years old.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. 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. Age: Permian, 252 to 299 million years old. About 10 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 6 mi of the line.
Sandstone. Age: Permian, 252 to 299 million years old. About 3 mi of the line.
Sandstone, conglomerate. Age: Permian, 252 to 299 million years old. About 3 mi of the line.
Shale, siltstone, sandstone. Age: Permian, 252 to 299 million years old. About 1 mi of the line.
Gypsum, dolostone, shale. Age: Permian, 252 to 299 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 5 smaller units along the line are not listed.

A raindrop that lands in Hobart reaches the Gulf of America by way of Elk Creek, the North Fork Red, the Red River, the Atchafalaya and the Lower Atchafalaya: about 1,190 river miles.
960 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hobart; river miles along the main stem, rounded.
Hobart has a humid subtropical climate. Summer afternoons average 97° in July; winter nights fall to about 28° in January. About 28 inches of rain fall in a normal year.
On November 14 Hobart normally reaches 62° and falls to 39°. The record high is 84°, in 2020; the record low 14°, in 1916. The most rain on this date, 1.47 in, fell in 1924.
Normals 1991–2020 and records since 1910 at Hobart Municipal Airport, 3 miles southeast. NOAA, through RCC-ACIS.
