@emsque:
Exactly #40YearsAgo Doug Geisler was asleep atop Manastash Ridge Observatory. An astronomy grad student, he'd just logged his first excellent night at the telescope for his PhD thesis. He was the only person on the summit, ~90 miles from #MountStHelens... #MSH40

    A scientist named David Johnston was on Mount St. Helens when the explosion happened. His body was never found.

      Good catch. That did confuse me when I read it but I didn't come back around from my wiki rabbit hole to figuring it out.

      I changed the title. Better? Edit: GPS data puts it at ~140 miles from 46°11′28″N 122°11′40″W (Mount St. Helens) to 46.9511°N 120.7245°W (Manastash Ridge Observatory), so I have changed it to that...
