Hallo Leute,
Wir haben einen digitalen Plan von S2 gefunden. Dieser entstand 1958! und wurde 1993 modifiziert. Die urspruenglichen Raeume (Living Quarters, Labs...) waren alle von der Oberflaeche in den Schnee gegraben worden. Heute liegen sie 15 unter Eis und Schnee. Alle Gaenge sind noch zwischen 50cm und 1m hoch, das gleiche gilt fuer die Raeume. Besichtigen kann man das ganze nur mit schwerem Kletterzeug (Geschirr, verschiedene Karabiner, Ankersystemen zum Sichern, Djumas zum hochklettern an Seilen...) Helm und Helmlampe. Die Waende sind mit Eiskristallen uebersaet, und ueberall findet man noch altes Geraet und alte Lebensmittel (Olivier hat sogar zwei alte Eier gefunden).


 
 
Und fuer alle die es interessiert, hier noch die offizielle (englische) Beschreibung von S2, der Anreise, der Besichtigungsmoeglichkeiten und (fuer unsere Alpinisten) die notwendige Ausruestung
 

S2 is 80klm away, up on the Law Dome, the huge ice plateau, behind Casey.
         It was opened in 1957.

        They had a “Jamesway” hut, generator, storage, and snow laboratory all dug in the snow, joined with a roofed
        trench and then covered over with snow, and a shaft which they dug down into the ice, 36m deep.

        Over the years the snow has covered it all. But each year they returned and dug it out to do more experiments and
        take more ice samples.
        When they finally closed the site (around 1966) they were living in an underground ice cave/tunnel, the hut and all,
        buried. Now there is a 15m deep shaft to the original dwelling which consists of a tunnel joining the hut and the
        36m shaft.

  THE GUIDE
 
        The journey to S2 is via S1, Lanyon Junction, and then Blyth Junction. S2 lies only 4.5klm from the Antarctic
        circle. The distance is approximately 80klm from Casey to S2 and towing a RMIT van with a Hagglund takes from
        5 to 7 hours.

        Five 20ltr Jerry cans of ATK should be taken.

        Navigation is best done using the GPS. Radar is useful but not useable unless all passengers are in the front
        compartment of the Hag’, a problem if there are more than four on the trip.

        S2 is easily identified by the large 2.4m high 1.2m wide box which stands over the shaft and can be seen for miles
        around.
        There is an access hatch in the top of the entrance box, however it is easier to access if the down wind side is
        removed. It is held in place by hex head tech screws.

        The initial 15m shaft has ladders to the bottom. A static rope should be hung from a sling/Krab’ diversion on the
        top hatch and a belay rope used through the removed side. Both ropes can be tied off to the RMIT van sled. If this
        is not available, the Hag’ or other large vehicle can be used. However, if a vehicle is chosen for anchors the keys
        must be removed from the ignition! If you choose not to use either of the above options remember to pack suitable
        alternatives.

        The first person down may wish to abseil with a safety rope, belayed from above. Cleaning snow off the ladder
        rungs. Those following can climb down but should still use a belay from above. When exiting this shaft the first
        person would run a jumar up the belay rope and then belay the other party members up.

        The passage immediately after the entrance shaft has been shored at some time in the past. The shoring is made
        from 15mm ply. This has buckled under pressure and bows into the passage. This restricts access somewhat
        although the side walls of snow behind the shoring have not bulged with it and a cavity exists between.

        All parts of the system have been explored and found to be reasonably solid and secure.
        Five meters from the final shaft on the right wall is a small hole leading to an old access hatch. This was dug out to
        enable a look in. It is a tight squeeze.

        The deep pit at the end was rigged with a snow stake and four ice screws, which are joined with short lengths of
        static rope, and have been left in place for future parties.

        All party members should use a safety rope to protect the descent. The ladders are fairly insubstantial.

        Only one person should ever go down at any time. To reduce the risk of trapping people at the bottom should a
        ladder fail, and reduce the risk of injury from falling objects, cameras, radios, etc.

        The ladders have been made more secure with the addition of ice screws and lengths of 5mm static rope.

        A trip from one end of the system to the other is possible with the Sked stretcher. This would be a clean run with
        one three point turn at the Jamesway hut area. In practice, however it may be easier to extract someone by pulling
        them with a sling under their arms.

        All party members should be familiar with “Z” drags as this could be the only way to extract an injured person.
 
 

    RECOMENDATIONS

      1.Distance makes rescue from Casey difficult. Groups visiting S2 should have the resources to self rescue any party
        members in difficulty.
      2.Communication with Casey could be an issue. HF equipment and training is essential.
      3.There should be an optimum number of six people on any trip.
      4.At least two party members should remain on the surface at all times.
      5.A time limit should be set for any group under ground, before SAR is initiated.
      6.All party members should practice Z drags and self rescue immediately prior to departure.
      7.Party members must try to  remain in line of sight at all times. Sound does not travel.
      8.A belay rope should be rigged and all party members belayed up and down both shafts.
      9.A second static rope should be rigged and hung down each shaft for self rescue should a ladder fail. In particular
        the bottom shaft where it is preferred that the static runs through the landing hatches.
     10.Each party member must carry a torch, spare bulb, and batteries.
     11.A survival pack must be carried with the group at all times. Not dumped somewhere.
     12.VHF radios should be taken as communications through the ice are excellent.
     13.It should be noted that any trip on the Law Dome can be extended for long periods due
        to unforeseen weather
        conditions. Parties visiting S2 should take fuel and food to last a minimum of ten days
        in excess of their expected stay.
