Nine stones
adrift in the long blue

A survey of the Aureline Archipelago — nine inhabited rock-masses holding station between four and twenty-one thousand feet, and the people who keep them level.

Marker 01

Pale Kettle

Uninhabited. Ringed by nesting sheerbirds and a permanent cap of freezing mist.

How to read this guide

Each stone is logged by altitude, not by distance. The gauge on the right is your position in the column; scroll and you climb.

Verrow Shelf

The largest inhabited stone, and the only one with soil deep enough for orchards.

Four hundred and twelve residents, most of them second- or third-generation ballast keepers. The terraces are pinned to the windward face with iron staves driven in 1974 and never once replaced.

Little Ossary

A chapel, a well, and eleven graves — the only stone that drifts counter to the prevailing current, for reasons no surveyor has settled.

Marker 02

Thimble

Forty metres across. One tree.

Ledger

Ballast manifest

Every stone runs a deficit or a surplus. Keepers trade mass across the archipelago by cable-lift.

  • Verrow Shelf + 2.4 t
  • Little Ossary − 0.8 t
  • Thimble ± 0.0 t
  • Kestrel Bight + 5.1 t

12 900 ft · Conditions

The weather is a neighbour

Above twelve thousand feet the cloud deck stops being scenery and becomes infrastructure.

Keepers harvest it. Condensation nets strung between Kestrel Bight and the Ossary return roughly nine hundred litres on a good westerly — enough to keep both orchards and both wells honest through the dry months.

Marker 03

Grey Anvil

Storm-scarred, magnetically unreliable. Compasses lie within 200 m.

Instrument

Reading the drift

A stone at rest still moves. Three knots of lateral drift is nominal; above eight, the cable-lifts are cut and the archipelago spends a week apart.

Overheard

“We don't say up.”

“We say out. Up is where the birds went. Out is where we live.” — Ovie Sarn, ballast keeper, Verrow Shelf, forty-one years on the stone.

Getting between stones

There are three ways across, and two of them are cables.

  • Cable-lift, scheduled 4× daily
  • Cable-lift, freight on call
  • Glider, licensed dawn only
  • Glider, unlicensed discouraged

Marker 04

Sister Pins

Two needles, joined below the cloud line. Never landed on.

Residency

Kestrel Bight

Eight rooms let to surveyors, painters and the occasional meteorologist. Bring your own ballast; the stone will not carry you free.

Caution

The gap at 19 400

A dead band of still air where nothing holds station. Cross it under power, never under sail, and never alone.

21 000 ft · Ceiling

Above this, only weather

No stone has ever been logged higher. The survey ends where the air stops arguing with us.

Unnamed

Sighted twice, in 1998 and 2027.
