This is a longer version of 154th by adding the most continious connecting climb coming out of Mirrormont. Steeper bit at the bottom and steep switch backs again at the top. Good climb but with more extreme sections than the Zoo. Gain is a bit more than 1200'. Easier on the bottom after a short steep bit, harder on top. Tricky going down or up when it is wet. Some will want a mtn bike for this one.
