Camping amenities at Yellow Creek State Park, one of the first highways in the state, the Kittanning Path. This trail was used by the Delaware and Shawnee nations and by early settlers. Today, U.S. 422 roughly follows the old Kittanning Path and provides the main access to the park from Indiana and Ebensburg. Named for Yellow and Little Yellow creeks, which create the lake. The creeks have lots of yellow clay in the banks and bottoms.
