Dunning Mountain is a long, narrow ridge in central Pennsylvania, United States. It's part of the larger Appalachian Mountains range. This mountain is known for its interesting shape and the valleys around it.
At its northern end, Dunning Mountain meets a place called McKee Gap. This gap separates Dunning Mountain from another ridge, Short Mountain. A small stream called Halter Creek flows through McKee Gap. It heads west towards the Frankstown Branch of the Juniata River.
The southern end of Dunning Mountain connects to Evitts Mountain. Here, Dunning Mountain makes a sharp turn to the east. The valley created by this bend is known as "The Kettle." To the east of Dunning Mountain, you'll find a wide valley called Morrisons Cove. The town of Roaring Spring is located at the northern end of the mountain, on its eastern side.
Several roads cross Dunning Mountain. Route 869 goes over the southern part of the mountain, connecting the towns of Imler and Brumbaugh. Another road, Route 1042 (also called Sproul Mountain Road), crosses the mountain east of Sproul. Parts of Pennsylvania State Game Lands Number 147 are also found on Dunning Mountain. These areas stretch from the Juniata River south to the hills near Roaring Spring.
What is Dunning Mountain Made Of?
Dunning Mountain is located in the Ridge and Valley area of the Appalachian Mountains. This region is famous for its long, parallel ridges and valleys. Dunning Mountain forms one side of a large, upward-folding rock structure called an anticline. Tussey Mountain forms the other side of this structure.
The very top of Dunning Mountain is made of a very strong type of rock. This rock is called the Silurian Tuscarora Formation, which is a type of quartzite. Quartzite is a very hard rock that resists erosion (wearing away by wind and water). This is why Dunning Mountain stands tall as a ridge, while the softer rocks around it have worn away over time.
