People are usually pretty tight lipped when it comes to shed hunting spots. Spots that continually produce are kept secret almost moreso than hunting spots.
The only time I have really spent time up that way is when my dad and sister each drew their Mt. Spokane moose tags. We only saw a handful of elk, though we did see a few branched bulls. From what I understand they're pretty scattered and in some thick country.
You're in good country for whitetail sheds though, I'd focus on those and if you stumble on moose or elk sheds, it's a bonus!
