Branford Center’s center stands about 50 ft above sea level. Within three miles the land runs from 0 ft to 270 ft, a difference of 270 ft: rolling country. Open water lies within three miles. The highest named summit within 15 miles is Mount Sanford, about 930 ft, 14 miles north-northwest.
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 31×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone, shale. Age: Early Jurassic, 175 to 202 million years old. About 4 mi of the line.
Basalt, gabbro. Age: Early Jurassic, 175 to 202 million years old. About 4 mi of the line.
Gneiss. Age: Neoproterozoic, 542 to 1,000 million years old. About 3 mi of the line.
Shale. Age: Early Jurassic, 175 to 202 million years old. About 2 mi of the line.
Basalt, gabbro. Age: Early Jurassic, 175 to 202 million years old. About 0.8 mi of the line.
Basalt, gabbro. Age: Early Jurassic, 175 to 202 million years old. About 0.4 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.

Rain that falls on Branford Center runs only a short way, about 2 miles, to Long Island Sound and the Atlantic Ocean.
