Impacts of Outdoor Activities

I've often wondered how impactful I am in the woods.  Last week while descending from Half Dome I discovered a chilly, hillside spring that bubbled air (?) every few moments.  The Forest Service attempted to hide it but failed to see the temptation of their cover material.  While resting I was very careful to leave the area as undisturbed as possible save for the Mora knife that dropped from my pack unbeknownst to moi.  This article describes our impact and some hints at change: Outdoor Impacts

Dispersed Camping and Noise Map

Many seasoned full timers habitually disperse camp for very good reason.
