Subterranean conduit: Misc



Up to date as of February 07, 2010

From Lostpedia

Subterranean conduits form part of the DHARMA Initiative's infrastructure on the Island during the 1970's.



In architecture, the word subterranean conduit can be used to refer to an artificial underground waterway, or electrical, communications, and HVAC passages or underground tunnels.


  • The conduits were mentioned twice in the blast door map.
    • "SUBTERRANEAN CONDUIT" located at the top right of the Swan diagram: under “x4 y8 z15”. (the first three numbers)
      • A reference to the same three numbers is found under the Flame diagram in the form of three square roots: "√16, √64, √225" (the answers to which are 4, 8 and 15)
      • written over-top the circle that says “I am here”
  • Alex says in "Not in Portland" that there is no tunnel between Hydra island and the main island.

Cable Map

Main article: DHARMA cabling map
Promotional still of the cable map showing the barracks and subterranean passages

According to the map, there are four passages leading from the Barracks to areas beyond the sonic barrier. Two are marked as being subterranean. The other two are not. Of the passages marked as subterranean:

  • One leads from the barracks to the Northwest, then splits off after about 3.5 miles at a point "20' deep". This split is a hexagon on the map just outside the sonic fence and might be a hatch or room. One branch heads North and another heads West.
  • The second exits just North of East with another hexagon about 4.5 miles away, again outside the sonic barrier. This passage leads to the Flame.

Of the passages not marked as subterranean:

  • One exits to the Northeast, and again leads to the Flame.
  • The second exits just South of West and splits immediately before the sonic barrier with one branch heading North, intersecting and crossing the West split of the Northwest tunnel, and another heading Southwest.

From the Jigsaw Puzzles

  • The backs of the Official Jigsaw Puzzles revealed that the "E.E.P" notations on the blast door map stands for Emergency Escape Protocol. This is mentioned in relation to the subterranean conduits on the blast door map.
