Please join Uber Adventures (http://uberadventures.net), Canyoneering California (https://www.meetup.com/canyoneering), and Todd Martin (from Phoenix) for our monthly community gathering. In addition to our usual discussions and socializing, this author and filmmaker will lecture/present on exploring the canyons of The Grand Canyon (Grand Canyoneering) and will screen his film: "Last of the Great Unknown."
