kinda of a long ways from kfalls but east of Lakeview/west of Plush (Warner unit) there are tons of yotes....not sure if it is because of the Hart Mt. refuge or what but if you can get over there you will find them.
Blade. Where about are you talking. Is it around Coyote Hills? Between Lakeview and Plush is mostly mountains and I was over that area two weeks ago and alot is not accessable.
I killed 17 in the warner unit scouting for antalope this last year. There was a really bad die off in September from what I heard due to parvo. Coyote hills is a good place to start.
