Climb easy to moderate ice up to a large ledge at the base of the rock. Tic Tac is the bolted line that is to the left. Climb the vertical and technical wall to the ice above. This route is sustained in difficulty and definitely high quality. M8 is the original rating, however, I have heard that some key holds have broken off and it might feel more difficult.
Location
Seamstress is located downstream from the lower bridge. It is the line just to the right of Tic Tac.
