Marble Canyon airport sits above the part of the Grand Canyon known as
Marble Canyon, but it's not in the Park Boundary or down in the Canyon.
Cliff Dwellers is nearby. Bar Ten is in Whitmore Canyon, which feeds
into Grand Canyon from the north. Helicopters bring rafters out of the
canyon up to Bar Ten to be flown out to Vegas. Tuweep (aka Tuweap) is
just north of the Park Boundary in Tuweep Valley. It is a dirt/clay
strip that used to be used to fly rafters and supplies to the river.
