Wilderness areas have weeds pulled, overused areas revegetated, bridges built, and some even have old cabins, mines, and the Pasayton has an old airstrip. Some of the newer established areas are so close to highways that you can hear the traffic--which was why they weren't declared wilderness in the first round.
More areas are proposed.
There is a difference in the way the two agencies manage their wilderness. The Park Service, those people who wear the Dudley Do Right hats, allow chainsaws to be used to clear trails. The Forest Service, the people without those hats, do not. The local office did not even allow a volunteer crew to carry their chainsaws through a small part of the Goat Rocks in order to get to a non-wilderness trail. :msp_ohmy:
Meanwhile, we have people who can't read maps or compasses going into country that they wouldn't be able to a few years ago, with GPS units, cell phones, SPOT(emergency transmitter), ultra high tech metal hiking poles, not to mention the various synthetics that make their packs light enough to get in a ways.
A week of chainsaw noise? Heck, they won't notice it because they'll have their music plugged into their ears. Or their phones. I was amazed at the number of folks hiking plugged into music while we were working on a heavily used trail in the wilderness.
The ultimate crew would be some timber fallers.
In fact, I have wondered whether it would be cheaper to pay them to do work for a week, because it would/should be faster than any crew of "certified" buckers or volunteers. They'd have a support crew--a packer and some bodies to throw the chunks off the trail.
But that won't happen.
