Withering Heights climbs the north side of the northern tower. Repel of lower down the gully of loose rocks (watch out!) and you will quickly be wondering what you're getting yourself into.
This route is kind of a 15-20 foot wonder. Those 15ft. might be the most grueling climbing if you don't have your off-width skills down though. If only it kept going for 50 more feet!
Location
On the north side of the North tower. It's hard to miss because it is right below the large gully system that is full of loose rocks. Just be careful top-roping for rope placement.
Protection
You can clip two of the new bolts from "Gun Fight" in the first 20-30 ft, or a couple BD #2-4. Then, big bros. A couple nut placements here and there.
