I will be all over the #1, #2 canyon area this spring as well as clockum and up towards sugarloaf. I'll keep my eyes peeled for tracks/wolves. I've heard of them up clockum this past fall and in the upper entiat.
I know a miner up the chiwawa who has claimed to have seen wolves and grizzlies up there. I also know of a guy who grew up south of the tumwater canyon who has seen a grizzly and even talked to a WDFW official in the area about them. I have no doubts there maybe both in the Lake Wenatchee vicinity.
