We'll meet in the Sno Park early on day 1, eat dinner and camp there that night, wake up early on day 2 to get our ski on, and head out on day 2

This is a skimo trip so only for touring skis/splitboard mandatory.  On day 1 set up in the parking lot and practice our THIN ski anchors in preparation for the skimo/climbing season.  Day 2 we'll set out early, summit and have a nice ski back to the parking lot.

Like most ski mountaineering trips, participants should expect the entire gamut of snow conditions from wind scoured to pow to schmoo on our way down.
