Wurfberg

7402.4 m · net rise 609.9 m · total ascent 698.4 m · overall 8.2% · evidence quality B (good) · Mittersill · Salzburg ·

Shape: sustained — 35% of the climbing sits in a quarter of the distance; longest continuous stretch at 10%+ is 534 m.

Found purely from mapping and LiDAR data, and not yet matched against books, race records or lists — it may be well known to locals under a name we've never heard. It was cross-checked against the GIP.at road network, OpenStreetMap and a second terrain model, but a discovery can still be an artifact of the terrain model or the map. Treat it as a well-evidenced hypothesis until someone has ridden it. If you know this road, tell us what you found — photographs, corrections and local knowledge all welcome; the map links below let you scout it first.

≈ Overhead cover (tree canopy or structures) spans 10% 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.

Surface: GIP.at, Austria's official transport graph records no surface for this road; the map may tell you more.

Access: Listed 2026-09-13 (unrecorded surface, restricted road — Peter's class ruling): the road authority (GIP) marks this road restricted and has no surface record under the steepest 25 m window; the class's aerials show forestry and alm tracks, rideable on a mountain bike rather than a road or gravel bike, with the steepest 25 m usually a short ramp. Out of the annex and the rankings until a person confirms a road; the profile is shown as measured.

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).
