Arches National Park in the Round
Professor Bob has never been to Arches or Canyonlands national parks, though he's threatening to visit this spring. In the meantime, here's something to whet his anticipation -- a 360-degree view of Double Arch in Arches National Park.
Double Arch is one of the most accessible arches in the park. Located in the Windows Section of Arches, you can park your car directly in front of the arch and gaze at it, though walking up to, and through it, is the best way to gain appreciation of this icon.
Of course, after you check out Double Arch, you can explore North Window, South Window, Turret Arch, Cove of Caves, Cave Arch, the Garden of Eden, Parade of Elephants, and even Balanced Rock, as they're all right here in a tightly knit group.
