North America, United States, Wyoming, The Sphinx

The Sphinx. A second ascent of the very airy S. or skyline ridge was made by Hans Kraus, Delphine Wilde and Roger Wolcott on 11 August 1946, from a bivouac on upper Dinwoody Glacier. A partially new traverse, beginning near the S. end of the E. face and ending at the N.E. foot of the peak, was reported by Robert Parker and John Speck. Reaching the crest of the S. ridge involved several problems for the party, because of a scarcity of cracks for protective pitons. A direct descent of the N. face to the glacier was prevented by the bergschrund. To avoid this obstacle a long traverse E. above the glacier was necessary.
