Discovery of the Echo Room in Pettyjohn Cave and Second Mile of the Cave Survey
April 20, 1969 – Marion O. Smith and Richard Schreiber beginning mapping towards the Volcano Room from the principle front room and after 143.71 toes, station G8 the ground of a 5.2 foot vertical climb, reached the primary mile of survey. They persevered the survey north about sixty toes attaining a deep chasm that dropped off to the left. About 8 toes down you’ll be able to step into an aspect passage and proceed. The chasm was once no longer mapped. After a brief uphill distance a slender opening offers get right of entry to to what I name the Mid Room as a result of it’s about mid means between the principle front room and the Volcano Room. The passage from this room is immediately below the Autograph Room and you’ll be able to communicate simply between the 2 rooms.
The survey persevered throughout the Formation Room, then down a 14 foot climb at station G31 into any other room that the north finish was once no longer mapped. They exited this room on the south west nook and climbed all the way down to a window over taking a look the Volcano Room.
The Volcano Room is formed like a big funnel with steep facets and it leads all the way down to the move passage and the sump. For years the one means in was once to climb down a vertical wall thru a small window above the Volcano Room. I’ve unfastened climbed the wall, however it is rather uncovered. In the overdue 80’s any individual dug a bypass move slowly below and across the vertical climb as much as the window. To input this move slowly from the Volcano Room facet input head first, pushing your tools. You paintings your means upwards twisting as you move. Try to stick to your again as a result of you’ll have to bend up on the finish and when you don’t seem to be to your again you’ll no longer have the ability to bend up or flip over. If you’re going the opposite direction, you’ll want to move toes first and to your again. Going down hill is slightly easer.
The survey crosses the north facet of the Volcano Room and over a hidden ledge. Down thru a low room and any other hidden ledge and so they reached the doorway to the Mason – Dixon Passage and the Worm Tube. The survey persevered southwest throughout the Mason – Dixon Passage and stopped ahead of getting into the move slowly option to the Bridge Room. This survey ended in 1,100.17 toes T.H.C. (True Horizontal Cave). Total survey period now 6,380.65 toes.
May 18, 1969 – Richard Schreiber, Della McGuffin, Marion O. Smith, Allen Padgett and Bob Watkins entered the Worm Tube, however Allen and Bob needed to go out as a result of Bob turned into claustrophobic. The Worm Tube is 100 toes of very tight passage and the climb up into the Echo Room may be very difficult. The survey persevered go the laborious climb up into the Echo Room which was once came upon at the go back survey travel from the north finish. The survey persevered north to the Mystery Room. This survey ended in 1,058.13 toes T.H.C. Total 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 survey and explored a hollow main all the way down to a move stage. After surveying round on this decrease stage they then discovered a lead going up and into the Echo Room. The survey was once carried out across the perimeter of the room with two facet passages certainly one of which led again to the Worm Tube. The survey notes recorded a complete of 630.6 toes surveyed, on the other hand after I entered the knowledge it became out to be 1,134.89 toes T.H.C. Total survey now 8,573.67 toes.
June 21, 1969 – Richard Schreiber and Della McGuffin Surveyed the final shot to the again of the principle front room after which surveyed down throughout the breakdown from Station P13 to G12 within the passage to the Volcano Room. They then went to the tip of the survey within the Mason – Dixon Passage to proceed the survey towards the Bridge Room. After surveying around the Bridge Room they proceed northwest thru a gaggle of great formations and simple passage to the Over N Under Room. They surveyed the decrease segment of the Over N Under Room after which north to Five Points. From there it was once a brief distance to the Chute or Luge, it is going through each names.
At the ground of the Luge is a move passage. They surveyed up move to Station G193 after which returned to the Luge and surveyed down move to Station G205. They reported a complete of one,563.Eight toes, however it seems to be 1,738.10 toes T.H.C. Total survey now 10,311.77 toes,
July 12, 1969 – Richard Schreiber and Della McGuffin returned to the up move passage from the Luge and mapped simplest 262.74 toes attaining the two Mile Mark for Pettyjohn Cave. They won’t been conscious of the particular distance mapped and persevered on for a complete day of mapping.
