Aqualine

This is a Banks Lake classic, on the cover of the "Rock Climbs of Central Washington" guidebook. The route climbs the striking arête hanging out over the water. The opening moves up and left are a bit delicate and strenuous, but after that the arête is an easy jug climb in a fantastic position.

The left-most of the three routes (Supprehension, Prophylactic Crowbar, Aqualine) all located on the waterline of the west face of roadside rock (a.k.a. highway rock). The routes are near the southern end of the face, 50 feet north of the small islands the local swimmers call the "Tolon Keys". It is easy to approach by canoe/boat, but also possible to approach by land.

If the water level of the lake is high, it's likely you will be forced into a tenuous traverse to reach the start.

Guidebook says 6 bolts to an anchor and then 3 bolts more to a higher anchor. I don't remember a midway anchor, it was easy to go to the higher anchor. With a 70m rope one reaches the ground comfortably, so it's fairly certain a 60m rope is fine for lowering/rappeling.
