    If you think rocks are cool, this is the ride for you. We will be rolling from Mt Tabor to the Steel Bridge to Marquam Park, taking a look at exposed bedrock outcrops, and discussing what those rocks tell us about the deep-time history of our landscape. A limited number of Portland geologic timeline bookmarks will be available. The ride is approximately 10 mi at a party pace.
