Already alluded to was a similar incident in the 1930's. Missing in the Minarets is a well researched book detailing the incident. It might take the likes of a modern day Norman Clyde to find Matt if he can be found at all. One possibility is a bergschrund type of crevasse, which is where many had concluded Peter Starr might have met his demise. Norman Clyde knew better as it turned out.
