When you write about airways below the peaks -- obviously there are many of
those. But what I wondered, specifically, if there were MEA's lower than
the 91.177 minimum required IFR altitude (2,000' above the highest
obstruction within four miles of your flight path).



No, the MEA would follow the 2000 foot rule over the valley floor.



So far as the requiremnt (for pilots) for VFR altitudes, that would only
apply at 3000' or more AGL. So would probably not be applicable here.

Required altitudes for pilots flying OTP are the pilots problem. I
simply don't care.
