A town founded in 1705 and incorporated in 1711.
The bedrock geology consists of metasedimentary and meta-igneous rocks of the Connecticut Valley Terrane - allochthonous thrust sheets from the Taconic Orogeny and further deformed by the Acadian Orogeny. Ordovician Rowe and Ratlum Mountains schists and granofels (mostly metapelites and metaturbidites) are exposed mostly in the northern half of town. They are intruded by Ordovician plutons - primarily the Brookfield metadiorite gneiss, which includes microcline porphyroblasts that were likely originally phenocrysts, are exposed mostly in the southern part of town and around Hawleyville village. Minor calc-silicate and amphibolites are present, along with scattered granite pegmatites of Acadian age.
Coordinates are for the intersection of U. S. Route 6 and state Route 25 (the flag pole).
