Certain National Parks/landmarks may also have permanent or temporary flight restrictions as well. I believe the faa sets a TFR around the arch during July 4th activities.

The way I read the policy is "Launching, Landing or operating from lands or waters...". So in theory you could operate from outside park boundaries and fly into as long as you don't land.
