 Everything must be done by hand, even when fighting fires within the Designated Wilderness.The people who maintain hiking trails within the San Gabriel Designated Wilderness attempt to achieve a passable hiking experience within the wilderness that does not appear to be too greatly unnatural.To achieve such an effect, tree limbs and branches that must be cut back are finished with an effort to appear natural, bucked tree trunks that are removed from the trail are relocated so that they appear at a distance and do not look to have been cut by people, and even sawdust from crosscut saws will be collected and buried off of the trail.
