mallory cave trail 2023
june - august 2023 The project was built in 10 weeks with a crew of six. Large rocks were split using rock drills, feathers, and wedges and then moved with a Griphoist and rock bars. This project was deemed necessary due to users widening the trail to a 25 foot width, far exceeding the three-foot standard. Presumably, the trail had been widened due to heavy user traffic in combination with an unclear path. The finished construction includes 18 steps, 100 feet of mono-wall, 365 square feet of rock wall, and 50 feet of tread construction. Not pictured is a series of check steps helping to gain elevation to the staircase, rock walls that were built to protect the hillside below the staircase, and new tread leading to a slab intervention. The new build keeps in mind a sustainable grade in all directions, necessary for user experience and water dispersion. Work was completed for the City of Boulder Open Space and Mountain Parks in Boulder, CO.
