Balcony Camp on the West Rib of Denali underneath a display of ice crystal optics. A 22¡ halo, a parhelia or sun dog, the parhelic circle, and perhaps a hint of the Lowitz Arc (note that the Parhelia is not on the 22¡ halo, and that faint arcs emmanate up and down from the parhelia.) Denali National Park, Alaska. May 2006
