No -- there's a hill right next to it, and a bunch of mountains close
by. It's very different from Bishop (KBIS), which *is* surrounded by
comparatively flat terrain within a few miles at least. Take a look at
the aerial photo on Airnav -- http://www.airnav.com/airport/KMMH for
a good idea of what it's like...

Erm, following up to myself in the light of the new day, Bishop is KBIH,
of course, not KBIS (which is lovely Bismark, ND). I know this because I
once accidentally typed KBIS into DUATS to get the weather for Bishop
and was astonished to see a bunch of warnings about tornadoes, large
hailstones, thunderstorms, etc., on what was a basically CAVU day over
the entire country west of the Rockies...
