Upper Historic Hydrology Lab: Armoring
Roots are a major concern for any trail designer. They cut through trails, breaking apart rock walls and pushing paving stones out of place. They are forever uneven and slippery when they get wet, making them a legitimate safety concern. When a root crosses their trail, most designers simply rip them out.

Thick, matted patches of roots dot the Upper Historic trail. When faced with the question of how to deal with…
