April 20, 1969 – Marion O. Smith and Richard Schreiber starting mapping towards the Volcano Room from the primary entrance home and soon after 143.71 feet, station G8 the base of a 5.2 foot vertical climb, achieved the to start with mile of study. They ongoing the survey north about sixty feet reaching a deep chasm that dropped off to the left. About 8 toes down you can action into a facet passage and continue. The chasm was not mapped. After a shorter uphill length a slim opening offers access to what I get in touch with the Mid Place because it is about mid way among the key entrance home and the Volcano Space. The passage from this room is specifically less than the Autograph Room and you can talk easily between the two rooms.
The study ongoing via the Formation Home, then down a 14 foot climb at station G31 into a different space that the north conclude was not mapped. They exited this space at the south west corner and climbed down to a window in excess of hunting the Volcano Place.
The Volcano Home is formed like a big funnel with steep sides and it qualified prospects down to the stream passage and the sump. For several years the only way in was to climb down a vertical wall as a result of a smaller window over the Volcano Space. I have cost-free climbed the wall, but it is quite uncovered. In the late 80’s someone dug a bypass crawl under and close to the vertical climb up to the window. To enter this crawl from the Volcano Place facet enter head initial, pushing your equipment. You work your way upwards twisting as you go. Consider to keep on your back due to the fact you will have to bend up at the close and if you are not on your back you will not be capable to bend up or turn in excess of. If you are heading the other way, you will want to go ft to start with and on your again. Likely down hill is a minimal easer.
The survey crosses the north aspect of the Volcano Room and around a hidden ledge. Down through a minimal home and one more concealed ledge and they reached the entrance to the Mason – Dixon Passage and the Worm Tube. The survey continued southwest via the Mason – Dixon Passage and stopped in advance of entering the crawl way to the Bridge Home. This survey resulted in 1,100.17 toes T.H.C. (True Horizontal Cave). Total study duration now 6,380.65 toes.
May possibly 18, 1969 – Richard Schreiber, Della McGuffin, Marion O. Smith, Allen Padgett and Bob Watkins entered the Worm Tube, but Allen and Bob experienced to exit due to the fact Bob grew to become claustrophobic. The Worm Tube is 100 feet of extremely tight passage and the climb up into the Echo Place is quite rough. The study ongoing go the challenging climb up into the Echo Room which was uncovered on the return survey vacation from the north close. The study continued north to the Thriller Area. This study resulted in 1,058.13 ft T.H.C. Whole study now 7,438.78 toes.
June 10, 1969 – Richard Schreiber, Della McGuffin, Allen Padgett and Marion O. Smith returned to station G70 of the past survey and explored a gap leading down to a stream level. Right after surveying around in this reduce stage they then observed a guide heading up and into the Echo Home. The survey was done all around the perimeter of the room with two side passages a single of which led back again to the Worm Tube. The study notes recorded a total of 630.6 feet surveyed, however when I entered the knowledge it turned out to be 1,134.89 toes T.H.C. Full study now 8,573.67 toes.
June 21, 1969 – Richard Schreiber and Della McGuffin Surveyed the past shot to the again of the main entrance room and then surveyed down by way of the breakdown from Station P13 to G12 in the passage to the Volcano Place. They then went to the conclusion of the survey in the Mason – Dixon Passage to carry on the survey towards the Bridge Room. Soon after surveying across the Bridge Area they proceed northwest via a group of wonderful formations and effortless passage to the Around N Below Place. They surveyed the reduced part of the About N Below Area and then north to 5 Points. From there it was a limited length to the Chute or Luge, it goes by both equally names.
At the bottom of the Luge is a stream passage. They surveyed up stream to Station G193 and then returned to the Luge and surveyed down stream to Station G205. They reported a total of 1,563.8 feet, but it turns out to be 1,738.10 toes T.H.C. Whole survey now 10,311.77 ft,
July 12, 1969 – Richard Schreiber and Della McGuffin returned to the up stream passage from the Luge and mapped only 262.74 toes reaching the 2 Mile Mark for Pettyjohn Cave. They may not been mindful of the true length mapped and continued on for a complete day of mapping.
The uncooked survey information for the 2nd mile is available in pdf format at my caving world-wide-web website.
