Join Metro naturalist Ashley Conley and explore the rugged beauty of this unique lava dome as you wander through a white oak woodland in winter. Mount Talbert is part of a series of cinder cones and small shield volcanoes that began bubbling up almost 3 million years ago, leaving Mount Tabor, Rocky Butte and Mount Talbert in its wake. Participants gain a basic understanding of geology in the region from the stories in the stones and land formations along the way. Appropriate for ages 10 years to adult. Trails are rough and steep in places. $5 adult; under 18 free. Advance registration required; contact North Clackamas Parks & Recreation District at [email protected] or 503-794-8092.
