Spent some time in the enjoying the sun and watching runners up to Flattop. Dug one pit on the southwest facing aspect then skied that aspect. Ski penetration was getting deeper so we climbed back up to the wind tunnel saddle then skied a northeast facing aspect down to the Powerline. Back up again to blueberry hill and skied a north facing aspect to the parking lot at Glenn Alps.
