87° on Nov. 15, 2025, the hottest reading for this week of the year since 1893. Next is 85° in 1911.
Oologah’s center stands about 650 ft above sea level. Within three miles the land runs from 590 ft to 740 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Round Mound, about 840 ft, 6 miles east.
Under the town center the state geologic map shows Oolagah Formation (limestone, shale), from the Carboniferous, 299 to 324 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 61×. 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: Carboniferous, 299 to 324 million years old. About 7 mi of the line.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 7 mi of the line.
Shale. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Shale, sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 0.5 mi of the line.

A raindrop that lands in Oologah reaches the Gulf of America by way of Fourmile Creek, the Verdigris, the Arkansas and the Mississippi: about 1,090 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
600 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Oologah; river miles along the main stem, rounded.
Oologah has a humid subtropical climate. Summer afternoons average 94° in July; winter nights fall to about 28° in January. A normal year brings about 9 inches of snow; with the rain, that comes to about 41 inches of water.
On November 14 Oologah normally reaches 62° and falls to 40°. The record high is 79°, in 2020; the record low 13°, in 1916. The most rain on this date, 1.72 in, fell in 1909.
Normals 1991–2020 and records since 1893 from the Tulsa Area threaded record (Tulsa International Airport, 19 miles south-southwest). NOAA, through RCC-ACIS.
