The document discusses issues with erosion on hiking trails in a reservation, including muddy areas, poorly draining slopes, trail widening, abandoned sections, and rutting. It notes recurring damage from either poor trail locations or construction. Specific problem areas described include a creek crossing with converging trails, mud holes, a drainage culvert that was installed but then abandoned, and a hillside trail that has lost its outslope and collects water in the middle due to poor compaction. It raises concerns that mountain bike trails are not allowed due to cited reasons like erosion risk that are not consistently applied, while other groups are allowed to build trails without proper planning or environmental review.
