73° on Nov. 12, 1996, the hottest reading for this week of the year since 1948. Next is 66° in 1959.
Falcon Heights’s center stands about 4,120 ft above sea level. Within three miles the land runs from 4,070 ft to 4,460 ft, a difference of 390 ft: rolling country. The highest named summit within 15 miles is Hamaker Mountain, about 6,580 ft, 12 miles west-southwest.
Under the town center the state geologic map shows Tuffaceous sedimentary rocks and tuff (sandstone, siltstone, mudstone), from the Miocene to Pliocene, 2.6 to 23 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 8×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 14 mi of the line.
Basalt. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 4 mi of the line.
Sandstone, siltstone, mudstone. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 2 mi of the line.
Basaltic-andesite, basalt. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Basalt, andesite. Age: Miocene to Pleistocene, less than 23 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
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 Falcon Heights reaches the Pacific Ocean by way of the Klamath: about 250 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Falcon Heights; river miles along the main stem, rounded.
Falcon Heights has a cold semi-arid climate. Summer afternoons average 86° in July; winter nights fall to about 20° in December. About 11 inches of rain fall in a normal year.
On November 14 Falcon Heights normally reaches 50° and falls to 25°. The record high is 62°, in 2021; the record low 1°, in 1985. The most rain on this date, 0.45 in, fell in 1968.
Normals 1991–2020 and records since 1948 at Klamath Falls Ag Sta, 2 miles north. NOAA, through RCC-ACIS.
