So Master Link up to Inside Passage is fine, above that the snow depth increases pretty quickly. The fire roads above Quick Link are unrideable; there were four other guys pushing their bikes along with me. East Tiger Summit is about 3" deep as it's tree covered, Side Hustle starts at about 2" deep and is finally just wet by the connector to Iverson. Hoping for consistently below freezing temps and snow at elevation; time to swap the bike out for my skis!
