cotton wood can have a lot of silicate in it, especially if it's growing in sandy soil. i took one down a few years ago. it was in the bosque, by the rio grande, , stem 36" to 48", had to sharpen my chain after every cut, wore the chain down and threw it away. it was oregon but i don't blame them. cottonwood can be bad.
When it is big and dry, cottonwood here is hard as a rock. I had a wood salvage permit 3 years ago to cut and remove firewood from a flooded river area. There were some huge 3'+ cottonwood logs so I tried to cut them. That stuff dulled my chains pretty fast. So I moved on to getting the alder, cherry and fir. All the cottonwood stank when I burned it anyway, so I do not cut it any more. Smells like cat pee.
