I landed my Maule M5 on a very rough strip on top of the 4,396' Mt. Susitna, also called The Sleeping Lady, and got some pretty interesting drone video around an old military weather station. The strip is 800+ feet long, but very rough, despite having the rocks moved to the sides over the years. What was weird about this strip is that it looked uphill from wherever I was standing. The vibe up there also felt really weird.
