SDS. Make way up via crimps and arete, move out higher to left, match in huge jug, move out to sloper, flat cobble, hand heel match, mantle out to top jug. We gave it this name because for the stream running under the problem in spring.
This is on the Urban Adventure Boulder, on the way to the Punani Boulder before the bridge.
Pads and a spotter. Kinda nasty fall if you blow the finishing mantle.
