LS.0079-00: 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.
