01 · The Atlas

Six lines across
the high country.

Each sheet is walked, measured and drawn before it is printed. Distances are trail distances; ascent is cumulative; grade follows the alpine scale.

02 · Leave No Trace

We draw the mountain, we do not mark it. Every line in a CONTOUR atlas is walked on foot and recorded in pencil — no cairns stacked, no paint on rock, nothing carried out that wasn't carried in. The map is the only thing we leave behind, and it lives on paper.

03 · The Kit

What rides in
the survey pack.

Field-tested, weight-counted, and repairable in a hut with cold hands. The essentials we would not draw a sheet without.

A—01

Aneroid Altimeter

Brass-cased, hand-calibrated at every hut. The instrument every contour line is checked against before it earns ink.

±3 m · 0–6000 m · 84 g

A—02

Baseplate Compass

Declination-adjustable with a sighting mirror, for bearings taken across a valley when the cloud is coming in fast.

2° graduations · −40°C rated · 41 g

A—03

Waxed Map Case

Folds to a single 1:25 000 panel and sheds spindrift. The sheet stays readable in a whiteout, which is when it matters.

1:25 000 · IPX6 · 96 g

A—04

Field Journal

120 gsm weatherproof leaves that take pencil in the rain. Every route begins as a smudged sketch in here.

120 gsm · 192 pp · 210 g

A—05

Clinometer Loupe

Reads slope angle straight off the terrain to flag avalanche-prone gradients before a line is committed to the sheet.

0–60° · 8× lens · 55 g

A—06

Wax Pencils, set of 6

Moss, bark, signal, ridge, water and correction. The full palette a sheet needs, in a tin that fits a chest pocket.

6 leads · refillable · 38 g

04 · Field Dispatch

New sheets, from
the mountains we're on.

Four dispatches a year — a finished atlas sheet, the survey notes behind it, and the weather that shaped the walk. No noise.
