Explore the rugged winter beauty of a white oak woodland. Along the way, stories in the stones and land formations help you understand the region's geology. This unique lava dome is part of a series of cinder cones and small shield volcanoes that began bubbling almost three million years ago. Trails are rough and steep in places.
