4.72 inches of rain fell in two days, the most for this week of the year since records began in 1948. The next wettest, 3.11 inches, fell in 2020.
Greenbush’s center stands about 40 ft above sea level. Within three miles the land runs from 10 ft to 100 ft, a difference of 90 ft: gently rolling country.
Under the town center the state geologic map shows Omar Formation - Accomack Member (sand, gravel, silt), from the Quaternary, less than 2.6 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 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, gravel, silt. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.
Clay, silt. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Sand, gravel. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Sand, gravel. Age: Quaternary, less than 2.6 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.
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 Greenbush reaches Chesapeake Bay and the Atlantic Ocean by way of Deep Creek: about 5 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Greenbush; river miles along the main stem, rounded.
Greenbush has a humid subtropical climate. Summer afternoons average 86° in July; winter nights fall to about 29° in January. A normal year brings about 8 inches of snow; with the rain, that comes to about 43 inches of water.
On November 14 Greenbush normally reaches 59° and falls to 41°. The record high is 77°, in 1993; the record low 21°, in 2019. The most rain on this date, 1.27 in, fell in 1995.
Normals 1991–2020 and records since 1948 from the Wallops Island Area threaded record (Wallops Island Nasa Test Facility, 18 miles northeast). NOAA, through RCC-ACIS.
