The following cliffs will be closed to climbing beginning March 1, 2012: Angels Landing, Cable Mountain, The Great White Throne (beyond single- and double-pitched climbs), Isaac (in Court of the Patriarchs), The Sentinel, Mountain of the Sun, North Twin Brother, Tunnel Wall, The East Temple, Mount Spry, The Streaked Wall, Mount Kinesava, and the Middle Fork of Taylor Creek. All other cliffs will remain open to climbing.
The approach to Isaac is straightforward and takes about one hour.
An involved descent (a day in itself) down slabs to the northeast entails multiple rappels to gain the drainage between Isaac and Jacob. A total of approximately 11 rappels is required for the decent.
From the T-intersection of Zion Canyon Road-Mt. Carmel Highway, the Court of the Patriarchs pullout is approximately 1.7 miles. Hike toward the Virgin River, cross the bridge, and follow a climber's trail to the base of the formation.
Mountain Project's determination of some of the classic, most popular, highest rated routes for Isaac:
Tricks of the Tramp is easily located at the base of the prominent central buttress of Isaac. The climb starts in a clean 4-inch crack located 50 feet to the right of the major chimney system. Pitch 1: Climb an enjoyable 5.10 hand-to fist-to offwidth crack past some fixed protection to an obvious ledge on the left.Pitch 2: Continue a few feet up the crack, place a large cam, and fire up the impending offwidth to a bolt and take a deep breath. Continue comfortably to a fixed belay. Pitch 3: ...[more]Browse More Classics in UT
I'm not confident the route may be rapped from the summit, with a bag, safely. Much debris in chimneys could rain down. The pitches through the ledges above "the Calvinator" would be treacherous. The original descent is dangerous and teams must remain focused so as not to cut a rope. Two anchors near the bottom have Star Drives pounded in by Lowe or vertically driven LA's on a precarious, sloping, ledge. I strongly recommend 70M ropes.If you haven't summited, why are you giving beta aboout descents?
Well, for starters I spoke with someone who has rapped from the summit down the route, so it can be done. I myself have rapped down the ledges above the Calvinator and it was a piece of cake, hardly treacherous. Also, if you intended to rap the route, you wouldn't be hauling above the ledges now, would you?
