This is a small island we found in the Skykomish river in Washington, had my friend Jughead F15 land first in his Cessna 170 to check if the surface was smooth enough for my plane.
Although it was short I applied brakes smoothly because hard braking is what makes rocks go up and damage the horizontal stab.
For take off also smooth power delivery to take care of the prop.

I installed the Alpha AOA in my 180 couple of years ago
