If you look at that trail map, it's right in the grouping of trees to the right of "cr" in crest trail. You traverse into that tree grouping and there's a little cave with a bunch of really shitty graffiti.
Good luck holmes! Just ask dreddy looking people on the chair. Everyone has their own spot and 99% of the people that ride here smoke weed anyways.
I just moved to Seattle from Michigan and have been skiing Steven's Pass a this year. I've yet to find any smoke shacks and found your post on this forum about shacks there. Do you mind letting me know where to find a few?
Thanks, and happy boarding,
