Key Features
 
- Historic British Base ‘W’, Detaille Island
 
Description
TOPOGRAPHY
Detaille is a small island set in the Lallemand Fjord off the Loubet coast. The ground is predominantly rocky with areas of gravel.
FLORA
In the absence of any detailed floristic survey, only one species of lichen has been recorded at Detaille Island.
OTHER
Base ‘W’ is designated as Historic Site and Monument No. 83. It is sited at the northern end of the island. It is noteworthy as a relatively unaltered British scientific base of the late 1950s, providing an evocative insight into the way the bases were occupied during this period. It was built in 1956 and closed in 1959 due to the difficulty of accessing the base. It was subsequently reoccupied for six months in 1965/66. During its short history as an occupied base it contributed towards the geophysical programme of the International Geophysical Year (IGY). In addition to the base building, there are also dog kennels, an emergency store, fuel drum and cargo depots, an anemometer tower and wireless masts.

Visitor code of conduct
BEHAVIOUR ASHORE
  • A record of each visit should be left in the Visitors Book, located in the base.
  • All boots and outdoor clothing should be cleaned of snow and grit before entering the building. All backpacks and large bags should be left outside the hut.
  • Artefacts should not be handled or removed from the site. Do not sit on chairs or other furniture, or lay objects down on tables or work surfaces.
  • Base ‘W’ has a large amount of material inside and around the outside of the main hut, including hazardous materials. This makes the base extremely interesting from a historical point of view.
  • Loose gravel, mud and snow should be swept up, and floors wiped dry after each visit.
  • No overnight stays in the hut are allowed. The hut is available for educational visits and, except in emergency circumstances, should not be used for any other purpose.
  • Smoking and the use of candles, matches or stoves are prohibited in and around the hut.
  • The hut windows are all covered with fixed shutters and so electric torches will be needed to see anything of the interior.
  • Visitors are to leave the base safe and fully closed up on departure.
CAUTIONARY NOTES
Boat drivers should be aware of submerged rocks on approaching the landing site.
The rocks at the landing site can be slippery when wet.
