Would it be legal to land a light plane in the Badwater Basin salt flats in Death Valley National Park?
Let me add that you can obviously land in the park, as you have runways at both Furnace Creek and Stovepipe Wells. So another way of asking is simply: do you have to have an official runway to land? Obviously, you would need to stay >= 500 feet from people, but people don't typically wander too far from the parking lot and that's a big area. Staying away from people wouldn't be too difficult, especially in July or August when there's basically no one in Death Valley.
