We recently visited a crew working at Grand Canyon National Park which lies just north of Flagstaff, where ACE’s Intermountain Region Headquarters are located. The crew was performing routine maintenance on the Bright Angel Trail, the most popular hiking trail within the Grand Canyon.
Each year, melting snow and ice cause erosion that can render parts of the trail unsafe for visitors. ACE partners with the National Park Service annually to perform restorative maintenance. “For this project, we are working on clearing a specific drain about 1.5 miles down Bright Angel Trail,” explained crew leader Isabel Grattan. “The drainage ditch on the inside of the trail was covered in rocks and boulders that were washed down after the snowmelt. This prevented the water from draining properly and caused it to destroy a retaining wall.”
The crew began the hitch by using wheelbarrows to haul all the rocks that had fallen into the drain down the trail so that NPS staff could use them to repair the retaining wall. Safety is always imperative during any ACE hitch, but it was even more important for this project because of the numerous hikers and equestrians traveling up and down the trail throughout the day. The crewmembers had to be very alert and communicative to each other and to park visitors to ensure a safe working environment.
The corps members worked hard throughout the hitch to move all the rocks from the drainage. The NPS employees then crushed the rocks with sledgehammers for use rebuilding retaining wall. By the end of the 9-day project, the crew and NPS had replaced a significant section of the wall with crushed rock that was 2 feet wide, 30 feet long, and 6 feet deep.
ACE will continue working with NPS throughout the spring to maintain the popular hiking trails in the park. The Bright Angel Trail is accessible from the south rim entrance of Grand Canyon National Park.
