Canyonlands (Needles section) is located in Utah. The Needles Section is a maze of natural spires, arches, canyons, grabens, and potholes. The Needles themselves are the primary attraction. These pinnacles are very nice and one section of the Needles, Chesler Park, is pretty impressive.
There is also a lot of rock art and ruins.
