This climb's data: OCL JSON — the full gradient ladder, quality flags and provenance in the OpenClimb Ladder format.

Surface: mixed (33% unpaved), according to each state's road inventory: .

Access: Ranked 2026-09-04 (D22, New England point-cloud arbiter): re-lined onto the bench the USGS point cloud finds; a plain road bed reads under the 25 m maximum and the page clears its door on the traced line. Trimmed 2026-09-15 at the tail dog-leg (a driveway, Peter's ruling); the steepest 25 m now reads 21.5 %.

Measured, not vetted. This page records what the laser record shows about the road's shape — nothing more. Nobody has necessarily ridden or inspected this road for the survey, and a page here is not a recommendation and no guarantee that the road is open, surfaced, rideable or safe. Gates, private sections, missing rights of way and hazards do not show up in elevation data. Check access and conditions on the ground and make your own judgment.

Profile

The map, profile and gradient chart share one position — move your pointer over them and the marker follows. Colors are the gradient bands; the shaded span is the steepest 25 m. Any 25 m figure is good to about a point either way (why).
