Dr. Gerald Michael Myers, 41, of Centennial, Colorado, disappeared on May 19, 2009, while attempting a solo ascent on the West Buttress of Denali (then Mount McKinley). He was last seen by another climbing party at Denali Pass, about 18,200 feet, and later reported at roughly 18,700 feet. Myers was wearing a red down jacket, black pants, orange ski boots, carried a grey daypack and used orange Voelkl skis; he had a tattoo on his left shoulder.

A large National Park Service search and rescue operation used high-altitude helicopters and mountaineering rangers to comb the upper mountain, focusing on Denali Pass and the summit ridge. Harsh weather and extreme altitude hampered efforts; no trace was ever found and the search was eventually scaled back and suspended. Myers remains listed as a missing person and his whereabouts have been unknown since that day on the upper mountain.

Did anyone on Denali in May 2009 see Dr. Myers or notice anything unusual on the West Buttress route?
