An Alpine Ascents International concessions guide came upon a 48-year-old climber exhibiting symptoms of a myocardial infarction at about 8,000 feet on the Muir Snowfield on the afternoon of August 8th. Climbing rangers responded from Camp Muir, while a litter team was organized and ascended from Paradise. He was packaged and moved via a ski patrol litter to a point where they were met by the litter team from Paradise. The man was carried out to Paradise, where he was transferred to the care of the crew of an Airlift Northwest helicopter that had landed at a helispot just below Paradise. Eleven people were involved in the rescue operation. Climbing supervisor Brian Hasebe served as IC for this operation.
