The Donald Trump administration not only wants to despoil national parks by opening them up to more commercial uses such as mining, it proposes a budget that would reduce an already pinched workforce. And, if that’s not good enough, it’s proposing huge increases in entrance fees to some of the most popular parks — from $25 to $70  for a seven-day car pass in peak periods.

If more mining, less help and higher fees drive down use, hey, they can devote still more treasured park land to mining, drilling and pastures. What would Teddy Roosevelt say?
The increased fees, nominally to pay for maintenance deferred on account of inadequate congressional support, would affect these parks:

At Arches, Bryce Canyon, Canyonlands, Denali, Glacier, Grand Canyon, Grand Teton, Olympic, Sequoia & Kings Canyon, Yellowstone, Yosemite, and Zion National Parks with peak season starting on May 1, 2018; in Acadia, Mount Rainier, Rocky Mountain, and Shenandoah National Parks with peak season starting on June 1, 2018; and in Joshua Tree National Park as soon as practicable in 2018.
