- Retaining Wall
A structure that prevents soil from slumping, sliding, or falling onto a trail.
A retaining wall is usually made of logs, stone, soil-filled bags, blocks, or paving materials.
Retaining walls are often used to provide stability and strength to the edge of a trail or stream bank.
Also called "Revetment", "Cribwall", "Cribbing", "Mono-Wall", or "Multi-Tier Wall".
The retaining wall kept our favorite trail passable by preventing erosion.
