This is located un the middle of the east face of the discovery wall, uphill where the climbers path begins to flatten out. From the path, head up about 15 feet to a large open area, where you will find the bulge that leads to the Swallow Crack.
Start on a bulgy face that leads to a wide left faced crack on a slab where excellent hands and feet are available. There is certainly some rock that will eventually pull out on this route, so use caution! After the crack, move left to the bolt, and climb some class 4 rock that will lead you to the top of the Discovery Wall.
This route is about 90 feet long, and due to the leftward movement of the route, top roping this roue either requires some interesting directionals and a long rope, or some ballsy climbers. A fall on a top rope from the anchors will swing you about 50 feet left and crash you into the slabby section of Fly-By (5.9+), the next climb over.
Protection
Bring some Friends for the crack, and you will find 2 pitons and a bolt along the way. Old pitons are not to be trusted however, so if you're uncertain, add some more pro!
This was my first "trad" climb. A single pitch, with good to great foot placements on the face of the crag/route. Some pro left by other climbers are in place with a couple of strategically placed bolts makes this an excellent place to practice trad climbing.
A great crack for placing gear, two old pins that still appear bomber and a monster exit muffin...add to it all that in the summer the routes get afternoon shade, a big airy rap from the large boulder on top when it's done, everything one could ask for.
