Yep, I worked for part of a summer in the islands of the Tongass Nat'l Forest, near Ketchikan, back in 72. We used a natural spar tree to log the side to a landing. The spar did double duty as the upper terminus of a second high lead setup on a skid road straight to the salt water.
On one side, the terrain was so steep and wet that the donkey (yarder on log skids), which pulled itself up the hill, pulled several stumps just getting up. Then, while guying the spar, several other stumps pulled out. The riggers were almost out of available stumps, but got the side set up.
