OverviewTis-sa-ack takes a spectacular line through Yosemite’s most vertical face. The climbing is relatively moderate but adventurous. The wall feels remote since the throngs of people on the Northwest Face are nearly out of sight and earshot. This climb is harder than the Zodiac but easier than Mescalito.
