Groveland’s center stands about 620 ft above sea level. Within three miles the land runs from 560 ft to 1,420 ft, a difference of 860 ft: hilly country. The highest named summit within 15 miles is Canadice Hill, about 2,260 ft, 13 miles east.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 13×. 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, siltstone. Age: Late Devonian, 359 to 384 million years old. About 6 mi of the line.
Shale, siltstone, sandstone. Age: Late Devonian, 359 to 384 million years old. About 6 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 5 mi of the line.
Shale. Age: Late Devonian, 359 to 384 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. 1 smaller unit 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 Groveland reaches Lake Ontario by way of Canaseraga Creek and the Genesee: about 70 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Groveland; river miles along the main stem, rounded.
Groveland has a warm-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 18° in January. About 29 inches of rain fall in a normal year.
On November 14 Groveland normally reaches 50° and falls to 33°. The record high is 67°, in 1952; the record low 20°, in 2014. The most rain on this date, 1.29 in, fell in 2011.
Normals 1991–2020 and records since 1945 at Dansville Municipal Airport, 7 miles south-southeast. NOAA, through RCC-ACIS.
