Burke Mountain Toll Road

3881.9 m · net rise 532.8 m · total ascent 535.7 m · overall 13.7% · confidence: good · Vermont · share

Shape: sustained — 29% of the climbing sits in a quarter of the distance; longest continuous stretch at 10%+ is 844 m.

Not yet matched against documented climbs — the measurement stands on its own.

≈ Overhead cover (tree canopy or structures) spans 27% of this route — detected by comparing the surface model (DSM, treetops and rooftops) against the terrain model (DTM, bare ground). Under cover the bare-ground model is built from fewer laser returns, so metre-scale readings can wobble; maxima whose window sits in a covered zone are marked ≈ below — less certain — the flag does not say whether the true value is higher or lower. Longer windows average over more clean ground and are steadier.

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

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.
