Mescal Trail - Tread Bench Problem and Solutions
Tread Bench - Although bedrock works well for a trail surface and is one of the features of this trail, problems will result in locations where the bedrock outslope is too great for hikers. In these locations users will find a path that is less steep and easier to walk. These sites will require one of the following solutions:
Pinch Points - A pinch point or gargoyle is the use of native materials to funnel users through a more narrow section of trail by making areas off trail less desirable. This option is likely to be more short term <5 years but is far less time consuming. It does not address the underlying tread issues.
Crib Wall (Rubble or Stacked) - A crib wall can be constructed to provide support for the tread. The use of a rubble wall is acceptable when the slope is less significant. This option is likely to have a lifespan > 5 years, but may vary significantly as will the time for construction depending on site slope and materials.
Modification of Bedrock - The bedrock can be permanently altered to create a more ideal walking and riding surface with the use of chisels, rock saws, rock drills, etc. This option is permanent but potentially time consuming.
