I was hiking in late winter/early spring when I stepped onto a deep pile of wet leaves that gave out. Ended up sliding a good 25 ft downhill, and the only thing that stopped me from falling 100 feet onto the rocks below was a small tree that went dead center between my legs. I sat there for a bit with my feet dangling over the ledge until the pain diminished and continued on.
Still enjoy hiking to this day, just a little more careful on where I step.
