A collapse in the logging track. A cave is visible beyond the narrow entrance. An "unpromising" dig.
In 2024, "a site in the woods with rock face and potential cave at base" was visited. It was suggested that "This seems to be part of a feature which probably includes 3687 and may represent a fault."
