81° on Nov. 15, 1993, the hottest reading for this week of the year since 1894. Next is 78° in 1902.
Queen Anne’s center stands about 70 ft above sea level. Within three miles the land runs from 30 ft to 210 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows Lowland Deposits (fine-detrital, coarse-detrital), from the Pleistocene, less than 2.6 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand, clay. Age: Miocene, 5.3 to 23 million years old. About 7 mi of the line.
Sand. Age: Paleocene, 56 to 66 million years old. About 7 mi of the line.
Fine-detrital, coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Sand. Age: Eocene, 34 to 56 million years old. About 2 mi of the line.
Sand. Age: Cretaceous, 66 to 145 million years old. About 1 mi of the line.
Sand. Age: Cretaceous, 66 to 145 million years old. About 0.8 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 Queen Anne reaches Chesapeake Bay and the Atlantic Ocean by way of Honey Branch and the Patuxent: about 55 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Queen Anne; river miles along the main stem, rounded.
Queen Anne has a humid subtropical climate. Summer afternoons average 86° in July; winter nights fall to about 30° in January. About 44 inches of rain fall in a normal year.
On November 14 Queen Anne normally reaches 57° and falls to 43°. The record high is 78°, in 1993; the record low 18°, in 1986. The most rain on this date, 1.96 in, fell in 1972.
Normals 1991–2020 and records since 1894 from the Annapolis Area threaded record (Annapolis United States Naval Academy Asos, 12 miles east-northeast). NOAA, through RCC-ACIS.
