has a vast array of natural resources throughout its rugged landscape. Within these resources, there are many sedimentary substances. In the valleys of the Appalachian Plateau there is an abundance of limestone. This limestone is still mined for cement and aggregate. Due to excessive mining over time, limestone fields are depleted in many areas but some are still relatively plentiful. Ironstone and coal are also among the plentiful natural resources found. In different regions of the Appalachian Plateau, enough plant debris accumulated to form peat, which upon burial, compaction and heating was made into the coal of the Appalachian coalfields. Due to the abundant coal in the Appalachian Plateau, coal mining has been a staple of the area and has proved to be a very successful mining hub. Iron ore was once an extremely abundant natural resource but due to the thin layer of iron, over time it was mostly depleted. A very well known natural resource of the Appalachian Plateau is its land and soil. The soil is rich and it is ideal for farmland. Within the limestone found throughout the Appalachian Plateau there are many fossilized substances such as old plant and stems, which may help to explain why the plateau also has a rich amount of natural gases and petroleum. Landmarks and state parks The Appalachian Plateau has many landmarks and public spaces to camp out, go hiking, and sight see. Allegany State Park in New York, Ohiopyle State Park in Pennsylvania, Hocking Hills State Park in Ohio, Cooper's Rock State Forest in West Virginia, and Cloudland Canyon State Park in Georgia are notable state parks on or along the edge of the plateau; there are many more state parks and state forests throughout the region, and Wayne National Forest and Allegheny National Forest lie on the Appalachian plateau as well.
