I have seen too many areas degraded by this kind of behavior; Lundy Canyon for example has been mashed down along the road right to water’s edge.
This guy (or gal), drove his pickup over grass and flowers in a very high use area along the streamside, apparently 100 feet being too far to go to a large paved area. Right in the spring when the vegetation is most sensitive of all, and the ground still moist, so it packs down as well. I left him or her a courteous note.
I assume most readers know who John Muir was. The irony of location (Yosemite border) and damaging it is just too ironic—what does the "H" mean exactly? One word comes to mind? I felt both piqued and mystified as top why anyone with this license plate could willfully damage the high country.
Problem is, once one person mashes things down like this, the next person thinks it is just fine also. Pretty soon, what was untrammeled grass and flowers becomes packed dirt and dust with compacted soil. At ~9500' elevation, it takes at least a decade to regenerate damaged areas, if erosion doesn’t take a whack at it also.
(2 days Later) Maybe these rocks will help the clueless. I wonder how long they will remain in place.
