At the risk of looking like an idiot, I'll mention that the Mountaineer's Route is on the West face, about a 10 minute hike left from likely bivy locations. Seagull and Lost Horizons are directly above the bivy and start with a left leaning gully with chockstone topped by a triple tiered roof -- just like Mountaineer's Route. From the large number of bail anchors we found on these routes, others have made the same mistake while aiming for Mountaineer's Route.
