Garvald to Redstone Rig°
12977.6 m · net rise 293.1 m · total ascent 511.2 m · overall 2.3% · confidence: needs confirmation · Rough Cleugh · East Lothian
Shape: sustained — 40% of the climbing sits in a quarter of the distance; longest continuous stretch at 10%+ is 166 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 OS road network, surface models and map tags, 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.
° The name is provisional: this climb is not yet matched to a documented name, so it was named from nearby map places. There is no evidence of local usage — (auto-named from gazetteer (hypothesis, unreviewed); discovered as 'Discovered lane (55.9006, -2.6102)'). Corrections welcome.

≈ Overhead cover (tree canopy or structures) spans 13% 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.
Gradient ladder what do windows mean?
| Window | Maximum | Located at | |
|---|---|---|---|
| 2 m (diagnostic) | ≈55% | 1618–1620 m | under overhead cover terrain reads 61.1% at 38–40 m across a structure — excluded |
| 3 m (diagnostic) | ≈46% | 1618–1621 m | under overhead cover terrain reads 60.7% at 39–42 m across a structure — excluded |
| 5 m | ≈39% | 1618–1623 m | under overhead cover terrain reads 52.6% at 38–43 m across a structure — excluded |
| 10 m | ≈27% | 1613–1623 m | under overhead cover terrain reads 41.2% at 33–43 m across a structure — excluded |
| 20 m | ≈21.0% | 1603–1623 m | under overhead cover terrain reads 32.9% at 30–50 m across a structure — excluded |
| 25 m | ≈19.8% | 1598–1623 m | under overhead cover terrain reads 28.4% at 25–50 m across a structure — excluded |
| 50 m | ≈15.6% | 1577–1627 m | under overhead cover terrain reads 18.6% at 2–52 m across a structure — excluded |
| 100 m | ≈13.9% | 1541–1641 m | under overhead cover terrain reads 15.3% at 1425–1525 m across terrain that holds no road surface (dense canopy, no bench) — excluded |
