Alex Chiu, 41, was ascending Mount McKinley's West Buttress climbing route with two others on Monday when he fell at a spot known as Squirrel Point, according to park officials.

Alex Chiu, an engineer and alpine climber, was on one of the most frequently used routes at Mount McKinley, the tallest peak in North America.

Poor weather conditions prevented search and rescue from sending a team to locate and recover Chiu's body until early in the morning on June 4.
