13° on Nov. 11, 2017, the coldest reading for this week of the year since 1948. Next is 15° in 1986.
Miles’s center stands about 1,330 ft above sea level. Within three miles the land runs from 1,160 ft to 2,180 ft, a difference of 1,020 ft: steep hill country. The highest named summit within 15 miles is The Winehead, about 2,380 ft, 5 miles west.
Under the town center the state geologic map shows Coburn Formation through Nealmont Formation, undivided (limestone, shale), from the Ordovician, 445 to 487 million years old.
The section below crosses 9 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: Ordovician, 445 to 487 million years old. About 6 mi of the line.
Sandstone, shale. Age: Ordovician, 445 to 487 million years old. About 6 mi of the line.
Quartzite. Age: Silurian, 422 to 445 million years old. About 3 mi of the line.
Limestone, shale. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Shale, sandstone. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Dolostone. Age: Ordovician, 445 to 487 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. 3 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 Miles reaches Chesapeake Bay and the Atlantic Ocean by way of Elk Creek, Penns Creek and the Susquehanna: about 180 river miles.
Lake on the way: Lake Aldred.
75 miles of the trip are on the Susquehanna.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Miles; river miles along the main stem, rounded.
Miles has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 18° in January. A normal year brings about 30 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Miles normally reaches 51° and falls to 31°. The record high is 64°, in 2011; the record low 20°, in 2004. The most rain on this date, 0.57 in, fell in 1997.
Normals 1991–2020 and records since 1948 at Lock Haven Sewage Plant, 12 miles north-northwest, 760 ft lower. NOAA, through RCC-ACIS.
