I have had many float plane trips in Canada and Alaska dodging rocks in rivers, trees at the edge of lakes, and mountain top rocks that the pilot thought several feet of clearance was plenty.
Had two other landings that were scarier than any of the pictured airports could deliver.
#1. Plummer’s Lodge landing strip, Great Bear Lake, Canada NWT. Boeing 737 flight from Winnipeg, landed on a rock and gravel runway.
Rocks bouncing off the bottom of the wings and fuselage sounded like a hail storm on a metal roof. Just got stopped short of water at end of runway.
#2. Unknown/unremembered make twin engined plane flight carrying 6 fishermen, three guides, and a pilot and another crewman from Quinhagak on the western coast of Alaska to Dillingham.
When we reached our destination, the wind was blowing 60+mph from the west. The tips of the trees were almost touching the ground. The Airport had only a N-S runway.
The plane could not land with a side-wind of ~40mph or more. So, the pilot landed on a short taxi-way and the width of the runway. He made a steep descent over a building, slammed the plane into the ground, locked the brakes, and reversed the props. I think we only went a few feet beyond the runway width.
Well there was a dehaviland twin otter in one of those pics.
