Yavapai College: Explore Coconino County – Hike Red Mountain and Keyhole Sink

Near the northern edge of the great field of volcanos that surrounds Williams and Flagstaff is an otherwise average cinder cone, about 1,000 feet tall, called Red Mountain. What makes this little mountain unique is how erosion has carved a spectacular amphitheater out of the heart of this extinct volcano, creating a magical landscape of cliffs, spires, and little slot canyons. While talking about the history and dynamics of the San Francisco Volcano Field, and the local ecosystems, we will hike into the heart of Red Mountain, enjoying our lunch inside the volcano.  After our main hike, we’ll travel back roads south to Parks, then west on Historic Route 66 to Keyhole Sink, hiking into this unusual feature with petroglyphs and a seasonal waterfall.  Hiking distance is about 4.5 miles, mostly on well-maintained trail; inside Red Mountain there’s some optional off-trail exploring. Activity Rating: Level 3.

Tuition includes ground transportation, box lunch and field instruction. Departs 8AM from Prescott campus.
