After a long, down-canyon contour along the Pipeline Trail, mountain bikers drop down the very steep, loose, rocky Rattlesnake Gulch Trail at high rates of speed. For those loving a technical high speed descent it can be fun, but because it is one of the first trails that can be accessed heading up the canyon from nearby Wasatch Boulevard it is a go-to for local hikers and dog walkers looking to get out for a quick excursion. The combination of descending mountain bikers and uphill hikers and dog walkers is a dangerous mix that needs a solution.
