Details & Itinerary:

This is Dr. Colbath’s nominee for the best short geology hike in Northern Arizona. Red Mountain is an extinct volcano that erupted approximately 700,000 years ago. A steam explosion from the northeastern flank of the cone exposed the interior of the volcano to erosion by running water, which carved a spectacular amphitheater from black, red and yellow eruptive materials, and sculpted exotic erosional landforms. We will get an early start to catch the morning light as we hike 1.3 miles along a gentle grade through the pinyon pine-juniper life zone into ponderosa pine forest. You will have the chance to collect xenocrysts, and learn to recognize lapilli, taffoni, hoodoos and slot canyons. Be sure to bring a camera for one of the most photogenic hikes in our local area.

Participants meet at the Red Mountain trailhead and bring a water bottle, lunch, snacks, hat, sunscreen, good walking shoes, a mask and your camera.

Previous Venture trips were supported with transportation to and from the museum in Flagstaff to the trip launch site in a large passenger van. However, that service will not be provided as COVID-19 remains a concern. The safest way to reduce exposure risk is to provide your own transportation to the launch site. Some folks may want to just meet there, others may want to caravan from the museum.

MNA will provide extra water and guide.
