Hi, Shane!
Good to see you were able to spot the Chelan Bighorns. Oddly enough, this is a herd I've never seen. I've passed thru the Chelan area many times on my way to Entiat to "shoot" the sheep there. I always took a few minutes to glass the slopes around Chelan to try to get a glimpse of the sheep, but never found them. Always had luck with those Entiat sheep, though.
Friends often tell me that they've see the Chelan sheep right along US 97, just north of the Beebee Bridge. I always look when passing thru there (which I do about once a week) but still haven't seen them. I hope to find this bunch by October so I can see them in the rut. It'd be more convenient than Entiat, which is about 45 minutes further.
