Trail 17 is a straight-through trail connecting trails 12 and 47C. As you drive trail 17 east to west along the old coalmine bench, you'll pass many other trails, including the upper exit of Barney Rubble. Trail 17 is located within the Eastern Reserve of Anthracite Outdoor Adventure Area (AOAA) and offers one of the most unique attractions, the U-joint tree. The tree, located at the eastern end of the trail above 47C, was once impaled by a flying U-joint. The joint is now rusty, and the tree has swallowed 3/4 of it, but it is still available for viewing. Beyond this attraction, trail 17 offers a moderately steep, rocky hill climb up what is known as Ski Slope. Ski Slope is the most challenging spot along the trail, which is otherwise a hard-packed dirt surface with occasional protruding rocks. This trail is suitable for any high clearance 4x4.
Be sure to reference the AOAA website for accommodation links, days and hours of operation, waiver, and pass purchasing links.
