A new concessions contract for businesses on the South Rim of Grand Canyon National Park will cost the park $100 million, an amount that could impact just about all operations in the park, Superintendent Dave Uberuaga said Wednesday. In the long run, however, the move stands to benefit both the park and its visitors, observers believe.

Three concession workers in Yellowstone National Park decided to float down the Lamar River the other day in tubes, but only two made it to shore. The third was swept down the Yellowstone River and hasn't been found.

How much should the National Park Service rely on volunteers? That's a difficult question, as there are teachers, retirees, and others with valuable knowledge and skills that the parks could benefit from, particularly as the agency struggles to make ends meet. But does Apple, or JP Morgan, or any Fortune 500 company rely as much on volunteers for day-to-day operations as does the Park Service?

Parks, especially those in locations with minimal night sky distractions from artificial light, can be great locations for observing—and photographing—celestial events such as Monday's so-called Super Moon. A number of parks offer special night sky programs, but your opportunities to enjoy those out-of-the-world scenes aren't limited to organized events. As the photo accompanying this story confirms, the right locale and timing can provide a chance for a super photo.
