The second gallery really nails this point home, and is comprised mostly of photographs. As it's more modern, much of the art is infused with irony and self-awareness to show off our dysfunctional relationship with the nature of Yosemite, which is both funny and slightly depressing.
Perhaps the best example of the negative impact of tourism on Yosemite is an unassuming black and white photo by Rondal Partridge, called "Pave it and Paint it Green." Thankfully, the area in this picture was restored back to its original, grassy state:

And on the flipside, there's the iconic "Woman with Scarf at Inspiration Point" by Roger Mitnick. At first, it appears to be another comment on the oversaturation of commerce in the Yosemite Valley. But there's something about that unnamed woman staring off into the distance ...

I can remember when I first rounded a bend in the road and caught a glimpse of the Valley in full. You see it, and you're speechless. Pictures don't prepare you, and all you can do is pull over to the side of the road and silently take it all in. Personally, while I'm inclined to reduce accessibility of cars into National Parks, I don't know if I could sleep soundly knowing that someone -
anyone - was denied their chance to see something so majestic.
It's a balance, I guess.
- Yosemite: Art of an American Icon runs at the Autry National Center before traveling to Reno and Indianapolis.
- Gallery One, 1855-1969 is open through January 21st. Gallery Two, 1969-Today is open through April 22nd.
- Admission is nine dollars for the museum, six and change if you've got your Triple A card on you. And who in L.A.
doesn't have Triple A?
- Go to freshen up your on-trail snapshot skills. And for map junkies, the permanent exhibit has some great early maps of the frontier explorations.
