Been out looking for straight bull pines and I have cut one down (pics to come). However, during my search I began thinking that really any straight stock of tree/bush would work. In fact its very possible the shaft/harpoon was milled wood acquired from Berkley. So I went back and looked at the historic photos of the group on their way to Deer Creek on horseback with some of their gear to see if a 10' pole was attached anywhere - but nothing. So I'm more inclined to think Ishi with an axe prepared one fairly quickly during their trip. The shaft comes up very dark on all the 4-5 photos Saxton Pope took of Ishi with it. This makes me think that Ishi had to quick dry it over fire (as well as some minor straightening - assumption). I cant remember how long those men were up there for, but I want to say it was a month (if anyone knows please chime in). So waiting for it to dry would have taken too long.
I am also going to cut down and Incense Cedar of similar dimensions to make as second shaft - replacement/back up. These grow all around me and I cant remember if they grow as far north as Ishi's homeland (I spent two months out there on a job and I should know!). They grow extremely straight. Does anyone know for sure if Incense Cedars grows up their - perhaps a little higher country? Thanks
