There are many flows here ranging from WI2 to WI4. These drips form directly on the highway where they cut the rock back to build the road. There is plenty of room on the side for the plow to push the snow aside so the belayer is safe from traffic. The tallest formation is about 50 feet.

There is a sign that reads: "Exchamsiks Backchannel Rehabilitation" within sight of the ice. It's one of 2 signs that say the this. This one is further west.
There is a side road that gets closed during the winter months you can pull off on within a short walking distance.
