April 20, 1969 – Marion O. Smith and Richard Schreiber commencing mapping towards the Volcano Home from the key entrance place and after 143.71 ft, station G8 the bottom of a 5.2 foot vertical climb, achieved the to start with mile of study. They ongoing the survey north about sixty ft reaching a deep chasm that dropped off to the still left. About eight toes down you can move into a side passage and continue. The chasm was not mapped. After a small uphill distance a slim opening presents entry to what I get in touch with the Mid Area due to the fact it is about mid way concerning the key entrance home and the Volcano Space. The passage from this place is straight under the Autograph Area and you can chat conveniently between the two rooms.
The study continued by the Development Space, then down a 14 foot climb at station G31 into a different room that the north conclude was not mapped. They exited this home at the south west corner and climbed down to a window around looking the Volcano Area.
The Volcano Room is formed like a large funnel with steep sides and it prospects down to the stream passage and the sump. For decades the only way in was to climb down a vertical wall via a compact window higher than the Volcano Place. I have no cost climbed the wall, but it is pretty uncovered. In the late 80’s anyone dug a bypass crawl below and about the vertical climb up to the window. To enter this crawl from the Volcano Area aspect enter head initially, pushing your gear. You get the job done your way upwards twisting as you go. Try to stay on your back again since you will have to bend up at the conclude and if you are not on your again you will not be in a position to bend up or transform above. If you are likely the other way, you will want to go ft initial and on your again. Heading down hill is a small easer.
The survey crosses the north aspect of the Volcano Room and over a concealed ledge. Down through a minimal place and an additional concealed ledge and they reached the entrance to the Mason – Dixon Passage and the Worm Tube. The study continued southwest by means of the Mason – Dixon Passage and stopped right before entering the crawl way to the Bridge Space. This survey resulted in 1,100.17 feet T.H.C. (Legitimate Horizontal Cave). Complete survey length now 6,380.65 ft.
May perhaps 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 simply because Bob became claustrophobic. The Worm Tube is 100 toes of quite limited passage and the climb up into the Echo Space is extremely difficult. The survey ongoing move the tough climb up into the Echo Place which was learned on the return study excursion from the north stop. The survey ongoing north to the Mystery Area. This survey resulted in 1,058.13 feet T.H.C. Whole survey now 7,438.78 toes.
June 10, 1969 – Richard Schreiber, Della McGuffin, Allen Padgett and Marion O. Smith returned to station G70 of the former study and explored a hole main down to a stream degree. Soon after surveying about in this decrease amount they then located a direct heading up and into the Echo Place. The survey was done all-around the perimeter of the room with two side passages 1 of which led back again to the Worm Tube. The study notes recorded a full of 630.6 toes surveyed, even so when I entered the data it turned out to be 1,134.89 ft T.H.C. Full survey now 8,573.67 feet.
June 21, 1969 – Richard Schreiber and Della McGuffin Surveyed the previous shot to the again of the primary entrance area and then surveyed down through the breakdown from Station P13 to G12 in the passage to the Volcano Space. They then went to the end of the study in the Mason – Dixon Passage to carry on the study towards the Bridge Space. After surveying across the Bridge Home they keep on northwest via a team of wonderful formations and effortless passage to the Over N Below Room. They surveyed the decrease area of the In excess of N Below Room and then north to 5 Details. From there it was a quick distance to the Chute or Luge, it goes by 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 noted a full of 1,563.8 toes, but it turns out to be 1,738.10 feet T.H.C. Full study now 10,311.77 feet,
July 12, 1969 – Richard Schreiber and Della McGuffin returned to the up stream passage from the Luge and mapped only 262.74 ft achieving the 2 Mile Mark for Pettyjohn Cave. They could not been aware of the true length mapped and continued on for a entire working day of mapping.
