Congrats on your tag, switchbackkid!
The bioligist's name is Craig Jourdonnais.
Unfortunately numbers are way down, but I think you can get it done.
The ridge between Sawtooth Cr. and Roaring Lion Cr. is called Goat Ridge. It is called that for a reason. that said, at one time or another, there have been goats in every single drainage in the Bitterroots.
Good luck!
