I found a lvl 70 and a 125 ( For me 150 is max ) near (kind of) the green Obelisk, as you come from the south where the river splits in 2, to the left is the swamp, go to the right until it splits again, that's where I found my 125, Also near the hill with a decent amount of metal on it to the south of the redwoods and swamp pretty much on the middle line I think, that's where I find them often
