Discovery of the Echo Room in Pettyjohn’s Cave and second mile of the Survey Cave

Discovery of the Echo Room in Pettyjohn’s Cave and second mile of the Survey Cave

April 20, 1969 – Marion O. Smith and Richard Schreiber started mapping in direction of the volcano room from the principle entrance room and after 143.71 ft, the G8 station on the backside of a 5.2 foot vertical climb, reached the primary survey mile. They continued surveying north for about 60 ft to succeed in a deep chasm that collapsed on the left. About eight ft down you’ll be able to enter a facet passage and proceed. The sinkhole has not been mapped. After a brief uphill distance, a slim opening offers entry to what I name the center room as a result of it’s about midway between the principle entrance room and the volcano room. The passage from this room is instantly beneath the autograph room and you’ll discuss simply between the 2 rooms.

The survey continued by way of the formation room, then down a 14-foot climb at station G31 into one other room, the northern finish of which was unmapped. They exited this room on the southwest nook and descended to a window overlooking the volcano room.

The Volcano Room is formed like a big, steep-sided funnel and results in the stream passage and sump. For years, the one manner in was to descend a vertical wall by way of a small window above the volcano room. I climbed the wall free, however it is rather uncovered. Within the late 80’s somebody dug a bypass ramp beneath and across the vertical rise to the window. To enter this crawl from the facet of the volcano room, enter head first, pushing your gear. You progress upwards twisting as you go. Attempt to keep in your again since you’ll must bend over on the finish and when you’re not in your again you will not be capable of bend over or flip round. If you happen to’re going the opposite manner, you will wish to go ft first and in your again. Taking place the hill is a bit simpler.

The investigation crosses the north facet of the volcano room and over a hidden ledge. Descending by way of a low room and one other hidden ledge, they reached the doorway to the Mason-Dixon Passage and the Worm Tube. The survey continued southwest by way of the Mason-Dixon Passage and stopped wanting coming into the Bridge Corridor driveway. This investigation resulted in 1,100.17 ft THC (True Horizontal Cave). The whole survey size is now 6,380.65 ft.

Might 18, 1969 – Richard Schreiber, Della McGuffin, Marion O. Smith, Allen Padgett and Bob Watkins entered the Worm Tube, however Allen and Bob needed to exit as a result of Bob grew to become claustrophobic. The Worm Tube is a really slim 100 foot passage and the climb into the Echo room could be very troublesome. The survey continued after the troublesome climb into the echo room which was found on the return survey journey from the north finish. The investigation continued north to the Thriller Room. This survey resulted in 1,058.13 ft THC Complete studying now 7,438.78 ft.

June 10, 1969 – Richard Schreiber, Della McGuffin, Allen Padgett and Marion O. Smith returned to station G70 from the earlier survey and explored a gap resulting in the extent of a stream. After surveying this decrease degree, they then discovered a path that ascended and entered the echo room. The survey was carried out across the perimeter of the room with two facet passages one among which led again to the Worm Tube. Survey notes recorded a complete of 630.6 ft surveyed, however once I entered the information it turned out to be 1,134.89 ft THC Complete surveyed now 8,573.67 ft.

June 21, 1969 – Richard Schreiber and Della McGuffin Inspected the final shot behind the principle entrance room, then inspected by way of the purlin of station P13 at G12 within the passageway to the volcano room. They then proceeded to the top of the survey within the Mason-Dixon Passageway to proceed the survey to the Bridge Room. After surveying the bridge room, they proceed northwest by way of a bunch of gorgeous formations and a simple passage to the Over N Below room. They inspected the decrease a part of the Over N Below room, then north to 5 Factors. From there it was a brief distance to the chute or toboggan run, it goes by each names.

On the backside of the Luge is a stream crossing. They took the present upstream to station G193, then went again to the sled and took the present downstream to station G205. They reported a complete of 1,563.8 ft, nevertheless it seems the THC whole survey of 1,738.10 ft is now 10,311.77 ft,

July 12, 1969 – Richard Schreiber and Della McGuffin went again into the uphill luge move and solely mapped 262.74 ft reaching the two mile mark for Pettyjohn Cave. They could not have been conscious of the particular distance mapped and continued for a full day of mapping.

Uncooked survey information for the second mile is offered in pdf format on my caving web site.
