From every direction, Grand Canyon is under siege. In fact, external assaults constantly threaten air, water, and the values essential to sustaining Grand Canyon as a national park. Uranium mines and tourist development currently pose some of the most serious threats the park has faced in its nearly 100-year history.
“Every 15 or 20 years, it seems, the canyon forces us to undergo a kind of national character exam. If we cannot muster the resources and the resolve to preserve this, perhaps our greatest natural treasure, what, if anything, are we willing to protect?”
