Unknown is an enjoyable sector of south facing gray limestone. As of 2020 this area contains 6 routes ranging from 6+ to 8- UIAA. It is characterized by single pitch sport and traditional routes that accend a slightly less than vertical face and enjoy a shaded belay area thanks to a nice line of pine trees that helps block the sun. The Rock quality on this area is medium/good and the routes pick some very nice lines with beautiful feachers.

Unknown is located above and to the right of the parking area. The quickest way to approach is walking up this steep slope above the trailhead. Be careful not to knock rocks down onto the parking lot. The more established option is to walk towards the picnic area on the main trail (150 meters) until you encounter a switch back intersecting the path that will bring you up to the cliff face. Approach time 30 seconds to 1.5 minutes.
