Green Island, or La
Motte, is a small, tidal island, about a quarter of a mile
out from the coast.
There is a car park at Green
Island and it is on the Number 1 bus route.
According to David E.
Johnston in his The Channel Islands - an Archaeological
Guide, Green Island was a promontory in prehistoric times, and
probably until the beginning of the 17th century AD. In 1911,
erosion exposed the first of a series of burial cists that were
subsequently excavated. There were at least 15 of them, rectangular
boxes made of slabs of the Island diorite, roofed with capstones,
tidily set out as a cemetery, orientated east-west. Most contained
fragmentary bones, and in only four did determinable skeletal
material survive. One was in a crouched posture, another a double
burial, adult and child. A large cairn of boulders was found to
cover most of the east end of the island and this may also have
been a funerary. Today, only hollows mark the site of the cists,
which have been reconstructed at the museum at La Hougue
Bie.
For how long Green Island is
accessible around low tide will depend on the height of the tide.
On the day I placed the cache it could be reached for at least two
hours either side of low tide. It is a ten or fifteen minute walk
to the Island from the slipway, the latter part over
stones.
Please take care when going
to find the cache, and plan your visit taking into account the
state of the tides, which can be checked here. For safety's sake, I recommend that you
attempt this cache only when the tide is going out.
The cache is a small
tupperware container with room for small swaps and travel bugs, and
geocoins.
