My climbing days are long past. For about 15 years back in the 80's and 90's I did a lot of cone collection contracts for the Forest Service, and BLM.
I've climbed in most districts of all the national forests in Oregon.
Typical day would be climbing to the top of a dozen 150' trees, some smaller, many larger.
I've climbed thousands (low thousands) of doug firs, pondo pines, larch, lodgepole pine, western white pine, and others I forget.
One year we had a contract up the north mackenzie river for sugar pine.
Ya cant spur sugars they had to be ladder climbed with these 8" wide by 10' tall stackable ladders.
One fatty I remember well was over 6' dbh and 120' to the first branch. you're not supposed to set more than 7 ladders, but I had 12 up that tree, and they were corkscrewing around it, had to half jump to get in the branches, the lower ones were as big as my thigh.
Still sends a bit of a shiver remembering it.
I'm in awe of guys like Gerry Beranek who went up huge trees with friggen 090s.
