Park at the tunnel. Cross bridge, hike along trail past a dark hut. Ice should be visible up and on the left. Wallow up snow through trees to the blue ice. 20-25 ft of vertical curtain with a cave on the right. Fun, short ice but beautiful setting. Walk off right. Beware of brittle ice, I broke a pick here. There is more ice around here for those with good noses. Some will not find this worth the effort...ah often there is solitude on weekdays.
