Oakland’s center stands about 260 ft above sea level. Within three miles the land runs from 140 ft to 520 ft, a difference of 380 ft: rolling country. The highest named summit within 15 miles is McGaffey Mountain, about 1,290 ft, 12 miles west.
Under the town center the state geologic map shows Silurian Sangerville Formation, Patch Mountain member (marble), from the Silurian, 428 to 445 million years old.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 17×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granite. Age: Devonian, 359 to 422 million years old. About 6 mi of the line.
Sandstone. Age: Late Ordovician to Silurian, 428 to 459 million years old. About 5 mi of the line.
Schist, slate. Age: Silurian, 428 to 445 million years old. About 3 mi of the line.
Shale, sandstone. Age: Silurian, 428 to 434 million years old. About 3 mi of the line.
Marble. Age: Silurian, 428 to 445 million years old. About 2 mi of the line.
Granite. Age: Devonian, 359 to 422 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. 4 smaller units along the line are not listed.

A raindrop that lands in Oakland reaches the Atlantic Ocean by way of the Kennebec: about 70 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Oakland; river miles along the main stem, rounded.
Oakland has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 9° in January. About 43 inches of rain fall in a normal year.
On November 14 Oakland normally reaches 47° and falls to 29°. The record high is 66°, in 1930; the record low 7°, in 1905. The most rain on this date, 1.01 in, fell in 1904.
Normals 1991–2020 and records since 1895 at Waterville Treatment Plt, 3 miles east-southeast, 200 ft lower. NOAA, through RCC-ACIS.
