Morrisons Cove (also referred to as Morrison Cove or Morrison's Cove), is an eroded anticlinal valley in Blair and Bedford counties of central Pennsylvania, United States, extending from Evitts Mountain near New Enterprise, north to the Frankstown Branch Juniata River at Williamsburg. The width of the valley varies from 10 to 15 miles (16 to 24 km) between Tussey Mountain on the east to the chain of Dunning, Loop and Lock Mountains on the west. Almost entirely enclosed by these mountains, the only openings in the cove are at Loysburg Gap in the south, McKee Gap in the west, and at Williamsburg to the north. The floor of the valley is mostly level, with many large fertile farm fields.
