78° on Nov. 11, 2020, the hottest reading for this week of the year since 1948. Next is 72° in 2012.
Colden’s center stands about 1,090 ft above sea level. Within three miles the land runs from 930 ft to 1,710 ft, a difference of 780 ft: hilly country. The highest named summit within 15 miles is Blue Hill, about 2,040 ft, 13 miles southeast.
Under the town center the state geologic map shows Machias Formation (shale, siltstone, sandstone), from the Late Devonian, 359 to 384 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 16×. 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, siltstone, sandstone. Age: Late Devonian, 359 to 384 million years old. About 18 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 5 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 0.8 mi of the line.
Shale, limestone. Age: Late Devonian, 359 to 384 million years old. About 0.3 mi of the line.

A raindrop that lands in Colden reaches Lake Erie by way of West Branch Cazenovia Creek, Cazenovia Creek and the Buffalo: about 40 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Colden; river miles along the main stem, rounded.
Colden has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 15° in January. A normal year brings about 109 inches of snow; with the rain, that comes to about 44 inches of water.
On November 14 Colden normally reaches 48° and falls to 31°. The record high is 67°, in 2010; the record low 8°, in 2019. The most rain on this date, 0.66 in, fell in 1992.
Normals 1991–2020 and records since 1948 at Wales, 9 miles northeast. NOAA, through RCC-ACIS.
