I drove past it on Friday, looks like a fun wave train with a lot of splashy waves.The new rapid at the top, dubbed "Hall Pass", is a kick in the pants! SO much fun. It makes 1400cfs feel like 3000. The constricted channel makes it fast, fun, and splashy. It's no where near a class IV, but the new horizon lines still give you the pucker factor. I've been running Shoshone for over 20 years and I100% would recommend.
Sarahkonamojo is exactly right about it shifting again next spring. You've got to catch this iteration while it's still there.
Grizzly is open again for shuttles. Sunday saw some traffic with the front range weekend warriors struggling to merge (typical front range driving, lol) but overall shuttles took ~10 min. Have fun out there!
