ACE Arizona has been working with the Arizona Trail Association on several different sections of the 800-mile trail. In September ACE had a crew led by Katherine Dickey and Natalie Kolesar working just outside of Pine, AZ. Over the course of two eight-day projects, the crew worked on general trail maintenance as well as building rock structures and building footbridges with timber construction.
The crew put in two puncheon foot bridges within approximately the first mile of the trail. The process of putting in these creek crossings involves debarking, “ripping” the log, hauling the split logs up to the puncheon sites and setting them in place. Ripping refers to the act of splitting the tree lengthwise; each half provides the walking surface of the bridge. The bark is first removed from the tree trunk because the bark holds in moisture, to keep these wood structures from rotting the bark is scraped off by hand. To set the logs, the crew members dig holes for smaller logs to sit in on either side of the creek. Those logs are then reinforced with crush (small rock fragments) to hold the logs in place. Then, the larger logs receive saddle notches so that they fit like puzzle pieces on top of their smaller counterparts.
The purpose of putting in bridges over creek crossings is to prevent erosion and sedimentation in the creek. This area of Arizona is a very delicate riparian zone. It is one of the few places in Arizona where you can see a multitude of tree species including maple and alder trees. This type of lumber work requires a lot of measuring, leveling, and precision with the chainsaw. ACE National Trails Trainer, Mark Loseth visited the crew and made sure that crew was entirely equipt with the tools and knowledge to get the work done.
During the second half of this project, the crew built armored drain pans along some of the eroded parts of the trail. The armored drain pans protect the path and direct water off of the trail. A multi-tiered rock wall and rock steps were also put in by the crew during the duration of this project.
ACE has been fortunate to have completed multiple sections of trail work along the 800-mile Arizona Trail and would like to thank our partners at the Arizona Trails Association. For more information on this trail follow the link below:
