Historically, G1 is the left flow only. The route follows the line of least resistance to a two-bolt anchor. It can be steep for a WI3, but is over relatively quickly. This route sees heavy traffic. It is often "stepped out" and may involve some hooking with tools rather than swinging. Many top-rope and lead possibilities exist as one moves right along the wall. These routes are up to ~80 feet and WI 4-5. Top-ropes can be set up on the numerous tree anchors by hiking right around the cliff band.
