ACE Arizona partnered with the National Parks Service at Sunset Crater National Monument. Sunset Crater is a cinder cone volcano that is located north of Flagstaff, AZ. Through the end of September the crew constructed a trail through the lava flow within the park.

The crew is being led by ACE crew leader, Tim Beck. This is a completely different type of trail building for the corps members.  A typical trail involves working with pliable dirt however, in this case the crew has had to learn to work with lava flow remains which is hard volcanic rock.

The ground in this area is comprised of lava rock that is unstable and dangerous to walk upon directly. To lay the foundation for the trail the crew begins by moving the lava rocks to fill in any gaps and cracks. Using double and single jacks the crew is crushing in lava rocks to flatten the ground into a trail. By rearranging lava rocks and spreading rock gravel the crew is creating a trail that sits several inches below the lava flow. The trail will allow visitors to walk amongst the lava flow which has not been accessible in the past.
