where it's heavily concentrated.
National parks were meant to preserve natural wonders, but over time have become amusement parks. Rather than use wilderness designation that forbids roads and mechanized travel and provides a similar level of protection, leaders focus on national park and national monument designation which is as good as flashing neon sign for hordes of people. They want people to tread all over that ground if it means more jobs and tax revenue.
I was reading KSL this morning about net immigration into Utah and where it is coming from, and the numbers were big, but not crazy. That being said, I suspect that those people who are arriving love the outdoors, as it's probably one of the main drivers for bringing them here outside of family. If you bring in 120,000 new people each year to the Wasatch Front, and 80% of those are the type to drive up the Cottonwood canyons or American Fork each weekend, that will absolutely overrun the place in no time at all. Before you know it, the solution is to permanently scare the landscape by increasing parking, opening new roads, or building gondola towers.
I don't really know what to do about it either, because people are free to build a life where they want and enjoy past times that they like.
