Expo 2007 (Cambridge Austrian Cave Science Expedition): mission statement (76 surface list)

• Gemshöhle area:
• Explore the QMs at ~ -25m in Gemshöhle (107) (description suggests non-draughting chokes, survey suggests QMs), and the ~-70m route to the Big Pitch for any horizontal leads, as this is about the same level as Brave New World, and <100m away.
• Explore, survey and tag 83 (specifically phreatic continuation beyond pitch).
• Pirat Schacht (157). Explored by someone other than CUCC, and apparently only partially descended by CUCC.
• Eislufthöhle area:
• Check surveys of 2004-01 (bivi cave) vs 99 - the legs seem misaligned in one or the other.
• "Batter Pot" is a potential entrance above Pancake Chips Aven in 76, which might provide an easier route in to at least some of Brave New World. It probably needs minor excavation work to make an easy entrance.
• Schneewindschacht (97) probably deserves a revisit, due to its proximity to 76 and a phreatic level known to have a continuing traverse - the "not even mentioned as tight" part before the entrance squeeze looks fun though!
• Look at potential "back doors" into 97 - there are numerous holes nearby.
• 105 lies very near 76 and on the same fault system that the original 76 entrances are formed in. 105 is probably just a ~40m blind shaft as the 1970s description says, but worth shoving a rope down to verify.
• Descend Hanger Pot with full caving kit and later in the expedition to see if the snow plug is passable. The "straight on" lead in the Boiling Tubes in Brave New World in 76 is heading for it.
• Recheck draughting icy tube in Ice Curtain Cave with crampons or an ice axe (probably best done late in expo).
• Refind 2004-04 and 2004-09 and surface survey, and take photos.
• Bräuninghöhle area:
• Look at possible phreatic passage at ~-55m in Bräuninghöhle (82), which corresponds roughly with the level of "Brave New World" in 76.
• Find and tag 84 (draughts, unexplored tube) and 86 (almost certainly refound in 2006 since there's only one shaft in the area which seems to match the description - no paint spotted yet though).
• Survey and check out any missed leads in 85 (~50m long, no rigging gear apparently) and 81 (~15m long, no rigging gear).
• 2006-70 needs a surface survey and the pitch descending.
• Marilyn Monroe Höhle (148) is described as ending at "a steep ice-climb for which no equipment was available". Also mentioned is a route which "terminates in a steep ice slope at the far side of the chamber". The cave has a good cold outward draught, so a revisit with ice gear might be productive.
• Hit Lists:
• Surface survey: 102 to 101main or other nearby entrance.
• Photograph: 83, 84, 86, 100, 160, 1987-02, 210 (done last year?)
• Tag: 98, 111, 112, 2004-05, 2004-06.
• Miscellaneous:
• Survey (and surface survey to) the mysterious "+" cave 2006-72 fairly near the Top Camp col.
• Refind 99-OB-01 (tagged and photographed and bearings taken in 1999; not explored or GPSed, and not found in a search in 2006).
• Try to refind 178. It was found shortly after Tantalus Schacht (177) on the same prospecting walk. 177 has proved impossible to relocate, but if 178 were found that might give us a better idea where to look.
• Look for 110 - it's further out than 111 and 112 which we found last year, and was found by the same people on the same surface walk. However, we looked last year and there's a huge area it could potentially be in so it may be a hopeless case.
