Example: Visitor-Created Trail Soil Subsidence (Erosion + Compaction) at Acadia National Park

This is an example of a “Condition Class 5” (active erosional processes underway) trail segment in saturated subalpine acidic soil over granite (insoluble, low pH buffering) parent material.

These roots shouldn’t be visible and degloved (bark stripped off by lugged boot sole trampling) under natural/non-trampled conditions.

Site: Forested shoreline east of Bass Harbor Head Lighthouse, Mount Desert Island Unit, Acadia National Park, Maine, USNPS
