Morrisons Cove[1] (also referred to as Morrison Cove or Morrison's Cove), is an eroded anticlinal valley[2] 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. The southern end of the valley drains to the Raystown Branch Juniata River via Yellow Creek through Loysburg Gap, and the northern end drains to the Frankstown Branch, via Clover Creek.
There are four boroughs and seven townships located in Morrisons Cove:
Altoona–Blair County Airport is located in Morrisons Cove. Pennsylvania Route 36 is the main north/south route through the valley from Loysburg Gap to McKee Gap. Pennsylvania Route 866 branches off PA-36 at Woodbury to Martinsburg.
Nittany Valley and Morrisons Cove, eroded anticlinal valleys (coves), near the western edge of the fold belt shown here, and Broadtop Mountain (a syncline east of Morrisons Cove) are examples of inverse topography, which is common in this geomorphic province.
