Description

This short interpretive trail can be done in conjunction with the Ape Cave Hike. The trail highlights the tree molds formed when the same lava flow that formed Ape Cave flowed through an old growth forest and incinerated the trees. The "two forests" are, of course, the vestiges of the woodland consumed by the lava flow and the forest that has since established itself in the same spot.

The trail is almost entirely a boardwalk as it passes over the moss-covered 2,000-year-old lava flow in an emerald woodland of western red-cedar, Douglas-fir, and western hemlock with an understory of vine maple, salal, and bear-grass. At the junction, go left to do the loop clockwise. Interpretive signs along the way explain the volcanics and tree mold formations. Some tree molds are vertical, i.e. the trees were still standing, and some are horizontal. You can climb down a ladder into a large vertical mold and crawl along two other horizontal molds. There are also some small collapsed lava tubes in the vicinity.
