79° on Nov. 11, 2020, the hottest reading for this week of the year since 1995. Next is 79° in 2024.
Lake of the Woods’s center stands about 390 ft above sea level. Within three miles the land runs from 250 ft to 490 ft, a difference of 240 ft: rolling country. The highest named summit within 15 miles is Clark Mountain, about 1,080 ft, 13 miles west.
Under the town center the state geologic map shows Mine Run Complex - Melange Zone II, from the Neoproterozoic to Ordovician, 445 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 43×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Melange. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 5 mi of the line.
Slate, schist. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Phyllite, schist. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Melange. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 2 mi of the line.
Metagraywacke, mica-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 2 mi of the line.
Metavolcanic. Age: Cambrian, 487 to 542 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 Lake of the Woods reaches Chesapeake Bay and the Atlantic Ocean by way of Flat 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 of the Woods; river miles along the main stem, rounded.
Lake of the Woods 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.
Normals 1991–2020 and records since 1995 at Fredericksburg Sewage, 17 miles east, 330 ft lower. NOAA, through RCC-ACIS.
