86° on Nov. 11, 1989, the hottest reading for this week of the year since 1920. Next is 85° in 1999.
Ramona’s center stands about 670 ft above sea level. Within three miles the land runs from 620 ft to 840 ft, a difference of 220 ft: rolling country.
Under the town center the state geologic map shows Coffeyville and Checkerboard Formations or Checkerboard Limestone (shale, sandstone, limestone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 44×. 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, limestone. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Shale, sandstone, limestone. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Shale, sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Shale, siltstone, sandstone. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Ramona reaches the Gulf of America by way of South Fork Double Creek, Double Creek, the Caney, the Verdigris, the Arkansas and the Mississippi: about 1,110 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 Ramona; river miles along the main stem, rounded.
Ramona has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 22° in January. A normal year brings about 8 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Ramona normally reaches 61° and falls to 35°. The record high is 80°, in 1988; the record low 12°, in 2018. The most rain on this date, 2.24 in, fell in 1985.
Normals 1991–2020 and records since 1920 at Bartlesville Municipal Airport, 17 miles north-northwest. NOAA, through RCC-ACIS.
