Marginal Line

This is a great approach pitch to Bookmark's Library Ledge, even if

Backflip

or

Bellyflop

are not taken. The 1st 20 feet will school ya in Lumpy flared cracks.... Hike up 50 feet left from the base of

Backflip

to a flat, sandy spot below a [straight] up groove, that is thin at first then widens. Those crystals at the start are might small for 5.9...but after a few foot shifts and opposition moves, the crack opens to easier jamming. Some nice 5.7 or 8 leads to a small ledge 50 feet below Library Ledge. One can traverse right to the anchors on

Bellyflop

and rap 75 feet or continue to the summit.

A standard Lumpy Ridge rack, with allowances for more gear if summitting.
