74° on Nov. 15, 1993, the hottest reading for this week of the year since 1957. Next is 72° in 1964.
Valatie’s center stands about 250 ft above sea level. Within three miles the land runs from 190 ft to 510 ft, a difference of 320 ft: rolling country. The highest named summit within 15 miles is Harvey Mountain, about 2,070 ft, 15 miles east-southeast.
Under the town center the state geologic map shows Nassau Formation (shale), from the Neoproterozoic to Early Cambrian, 521 to 1,000 million years old.
The section below crosses 13 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. 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: Neoproterozoic to Early Cambrian, 521 to 1,000 million years old. About 4 mi of the line.
Graywacke, shale. Age: Middle Ordovician, 459 to 471 million years old. About 3 mi of the line.
Slate, phyllite, schist. Age: Middle Ordovician, 459 to 471 million years old. About 3 mi of the line.
Shale, conglomerate, limestone. Age: Cambrian, 487 to 542 million years old. About 3 mi of the line.
Shale. Age: Early Devonian to Middle Devonian, 388 to 410 million years old. About 2 mi of the line.
Phyllite. Age: Neoproterozoic, 542 to 1,000 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. 7 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 Valatie reaches New York Harbor and the Atlantic Ocean by way of Kinderhook Creek and the Hudson: about 140 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Valatie; river miles along the main stem, rounded.
Valatie has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 18° in January. A normal year brings about 31 inches of snow; with the rain, that comes to about 44 inches of water.
On November 14 Valatie normally reaches 52° and falls to 34°. The record high is 71°, in 1989; the record low 14°, in 1986. The most rain on this date, 1.20 in, fell in 1972.
Normals 1991–2020 and records since 1957 at Hudson Correctional Facility, 13 miles south-southwest, 220 ft lower. NOAA, through RCC-ACIS.
