Karstwater — rain falling on limestone,
and everything that follows from it.

The whole register

All 23 guides, in walking order — onto the plateau, through the rock, out at the spring, into the pan, and on to the slope and the vat.

01 · Reculées

  • 1.1

    A valley that cuts backwards

    A reculée is a blind valley walled on three sides. It did not erode downstream from a river — it ate backwards into the plateau from a spring, undermining the cliff above until it collapsed, over and over.

    Out at the spring
  • 1.2

    The cirque head

    The closed end, where the spring is and the collapse happens.

    Out at the spring
  • 1.3

    Scree and retreat

    The rubble apron that records how fast the wall is going back.

    Out at the spring
  • 1.4

    Dry valleys

    Watercourses on the plateau with no water in them, and where it went.

    Onto the plateau
  • 1.5

    The plateau edge

    A hard line on the map that is a hard line on the ground.

    Onto the plateau

02 · Springs

  • 2.1

    The rock is the reservoir

    Limestone stores rain in fissures and gives it back at a spring, so the flow answers the weather with a delay measured in days.

    Through the rock
  • 2.2

    Swallow holes

    Where a surface stream goes underground and stops being visible.

    Through the rock
  • 2.3

    Dye tracing

    Colouring the water to find out which spring it comes out of.

    Through the rock
  • 2.4

    Flood response

    A karst spring can multiply its flow in hours. What that does downstream.

    Out at the spring
  • 2.5

    Hard water

    Dissolved limestone carried out and re-deposited as tufa.

03 · Salt

  • 3.1

    Brine comes up on its own

    Some springs here are salt, because the water has crossed a buried evaporite bed. The industry existed because the resource surfaced itself.

    Into the pan
  • 3.2

    Boiling the pan

    Shallow iron pans over fire, and the fuel that dominated the cost.

    Into the pan
  • 3.3

    Graduation towers

    Sheds packed with thorn bundles, trickling brine to concentrate it by evaporation before any fuel is burned.

    Into the pan
  • 3.4

    The half-circle plan

    A saltworks laid out as a geometric arc — production organised as architecture.

    Into the pan
  • 3.5

    The brine pipeline

    Moving the water to the fuel instead of the fuel to the water.

    Into the pan

04 · Vines & Marl

  • 4.1

    Grey marl

    The clay beneath the limestone edge holds water and warmth differently, which is why the vines are where they are.

    After the water · the slope
  • 4.2

    The slope is the vineyard

    Drainage, aspect and the frost that sits in the flat ground below.

    After the water · the slope
  • 4.3

    Wine under a veil

    A film of yeast left to form on the surface in a part-filled barrel.

    After the water · the barrel
  • 4.4

    The cellar in the rock

    Constant temperature without machinery.

    After the water · the cellar

05 · Fruitières

  • 5.1

    Cheese made in common

    A single farm could not produce enough milk in a day for one large wheel, so milk was pooled and the cheese was made and owned collectively.

    After the water · the vat
  • 5.2

    The copper vat

    Why the metal matters, and the shape that lets one person work it.

    After the water · the vat
  • 5.3

    The wheel and the cellar

    Size as a storage strategy: a big wheel keeps because of its own mass.

    After the water · the cellar
  • 5.4

    Turning and rubbing

    Months of handling in a cold cellar, and the rind it builds.
