[Utah-astronomy] Who is he?

Hi, Patricia just found a photo taken at Bald Mountain the last weekend in July 1981 (the weekend she and I met). It shows Brent Watson's monster Dob and two people. The guy on the right is Patricia's brother Tom but we can't ID the guy on the left. Anyone recognize the guy on the left? http://planet.state.ut.us/patrick/BLDMTN81.JPG Cheers! Patrick :-)
