Purgatory Conglomerate

Dating to the Carboniferous period, the Purgatory Conglomerate is a geologic formation in Rhode Island.

Purgatory Chasm
Purgatory Chasm, at the intersection of Tuckerman Avenue and Purgatory Road in Middletown (often mis-identified as being in Newport), is a narrow cleft on the east side of Easton Point which splits the Purgatory Conglomerate in a dramatic fashion. The chasm is 120 feet long, 10 feet wide at the top, and over 150 feet deep.
