As a hiker, you bear the responsibility to know the dangers of any piece of real estate you hike. Sadly today, we have too many going out without many of the 10 essentials, let alone knowing anything about the area they are hiking through. This is a known problem and should be accounted for before you walk on the trail.
This trail is a part of the John Muir Wilderness, which means it is going to be kept as close to its nature state as possible. This does not include putting a bunch of rock delineators along the trail.
Over the years, we have discussed solar latrines up along the trail and how you need an act of God to get them put back in because this area is covered under the Wilderness Act of 1964. Personally, I have changed my position on this from putting them back in to leaving it as is. If anything changes are made, it should be access.
