Ramah Bay is the site of an uncommon semi-translucent light-grey stone with dark banding called "Ramah chert". The Ramah chert outcrops in a narrow geological bed stretching from Saglek Fiord to Nachvak. At Ramah Bay the highest quality stone, for flaking chipped stone tools (mostly bifaces and projectile points), is most readily accessible. Discovered by pioneering Native American groups, which archaeologists identify as the Maritime Archaic Culture, around 7000 years ago, the stone was highly valued for its functional as well as spiritual qualities.
