The Lake Wilderness plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
79° on Nov. 11, 2020, the hottest reading for this week of the year since 1995. Next is 79° in 2024.
Lake Wilderness’s center stands about 440 ft above sea level. Within three miles the land runs from 260 ft to 490 ft, a difference of 230 ft: rolling country. The highest named summit within 15 miles is Clark Mountain, about 1,080 ft, 15 miles west.
Under the town center the state geologic map shows Metasedimentary Rocks Undivided, from the Cambrian to Ordovician, 445 to 542 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 46×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Tonalite. Age: Cambrian to Ordovician, 445 to 542 million years old. About 8 mi of the line.
Melange. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 6 mi of the line.
Metasedimentary. Age: Cambrian to Ordovician, 445 to 542 million years old. About 5 mi of the line.
Melange. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 4 mi of the line.
Metavolcanic. Age: Cambrian, 487 to 542 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 Lake Wilderness reaches Chesapeake Bay and the Atlantic Ocean by way of the Widow Tapp Spring Drain, South Wilderness Run, the Rapidan and the Rappahannock: about 140 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lake Wilderness; river miles along the main stem, rounded.
Lake Wilderness has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 25° in January. A normal year brings about 11 inches of snow; with the rain, that comes to about 43 inches of water.
