This is the obvious crack on the south side of the major formation (Sentinel Rock). Diagonal up and left in the gully to the base of the formal crack, stem through to clip a bolt and then enjoy the lie-back following the crack system to the first ledge. Make a few moves to a second little ledge, then follow the crack for approx 10' and then transition to the right and clip a bolt on the face, gaining access to the slightly over-hanging crack. Gain this crack and take it to the summit anchors.
This route shares the first 50' with Unforgivable Acts to where the crack dissipates.
To access Lost Arrow Spire, BB, and Sentinel Rock:
Park at the Breezy Point Parking Lot, follow the sidewalk to the NW for 60' until the sidewalk curves up and left. Depart the sidewalk and gain the old road bed and follow it for 300' until the road curves sharply to the left. There is a single track trail located at the curve that descends down from the road, follow this for 25' to intersect another trail on the left that follows the drainage down. Take this for approx 300' to the base of Lost Arrow Spire, BB, and Sentinel Rock on the south side of the formations.
Sentinel Rock is the major formation of the 3; located to the NE of Lost Arrow Spire and BB.
