83° on Nov. 12, 1989, the hottest reading for this week of the year since 1951. Next is 82° in 1999.
Bartlett’s center stands about 890 ft above sea level. Within three miles the land runs from 830 ft to 930 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Marmaton Group (shale, limestone, sandstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 4 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, limestone, sandstone. Age: Carboniferous, 299 to 324 million years old. About 12 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 7 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.

A raindrop that lands in Bartlett reaches the Gulf of America by way of Lake Creek, Hackberry Creek, Labette Creek, the Neosho, the Arkansas and the Mississippi: about 1,190 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 Bartlett; river miles along the main stem, rounded.
Bartlett has a hot-summer humid continental climate. Summer afternoons average 89° in July; winter nights fall to about 21° in January. A normal year brings about 8 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Bartlett normally reaches 57° and falls to 34°. The record high is 81°, in 1999; the record low 11°, in 1986. The most rain on this date, 1.57 in, fell in 1985.
Normals 1991–2020 and records since 1951 at Mound Valley 3 WSW, 16 miles northwest. NOAA, through RCC-ACIS.
