Discovery House Echo of John Petty and the second mile of the Cave Survey Cave

April 20, 1969 – Marion O. Smith and Richard Schreiber began mapping Volcano Room of the big hall and 143.71 meters, the G8 base station of one foot vertical rise in the first 5.2 km of the investigation. He went on to capture the north about two hundred feet to reach down a deep gorge on the left. About eight feet away you can go into a side corridor and continue. The gap is not mapped. After a short climb a narrow openingleads to what I call the main square, as it is about halfway between the entrance hall and main hall Vulcan. The transition from the room directly below the autograph room and you can easily talk between the two chambers.

Shooting continued through the training room, then a 14-foot climb to the police station in another room G31, to the north end was not mapped. She left the room at the southwest corner of a window and down the room volcano.

TheVolcano Room is the form of a large funnel with steep walls and the corridor leading towards the river and marsh. For years the only way to climb a vertical wall through a small window in the room Volcano. I have free climbed the wall, but is very exposed. At the end of 80, that someone is looking for a bypass dug under and around the vertical climb on them to the window. To solve this review from the head of the volcano silk first room, keeping your equipment. You work your way up to the curvego. Try to hold back because you must live up to the end and if you're not on the back, will not be able to bend or turn. If you go to the other side, you want the first to walk back. Going downhill is a bit 'easier.

The survey crosses the north side of the volcano room and a hidden edge. In a low room and second hidden corners and at the door of the Mason – Dixon Passage and worm tubes. The investigation continueswest of the Mason – Dixon started and stopped before the examination route to the bridge room. This study led to 1100.17 meters, THC (True Horizontal Cave). total record length is 6,380.65 feet.

May 18, 1969 – Richard Schreiber, Della McGuffin, Marion O. Smith, Allen Padgett and Bob Watkins, the tube worm, but Allen and Bob had to close because Bob was claustrophobic. The Tube Worm is 100 meters away from a path very close and climbingSounding is very difficult. The study will continue the increase in hard sounding travel standard survey at the end, North was detected. The survey continued north to the House Mystery. This study led to a total of 1058.13 meters absorption of THC is 7438.78 meters.

June 10, 1969 – Richard Schreiber, Della McGuffin, Allen Padgett and Marion O. Smith returned to the G70 station the previous survey and study a hole leading to the current level. AfterInvestigation at this level lower them a head start and enter the room echo. The study was carried out on the perimeter of the room with two hands, sometimes one of which led to the Tube Worm. The study notes that the total number of 630.6 meters in doubt, but when I entered the information, it appears that the total absorption of THC is 1134.89 m 8573.67 meters.

June 21, 1969 – Richard Schreiber and interviews McGuffin last shot in the back of the mainEntry and then examine the level of the station P13 to G12 in the transition to the Volcano Room. Then came the end of the recording Mason – Dixon recording passage space for the bridge to continue. After examining the bridge in the northwest room is still a group of beautiful formations and easy transition to more N Under Room. Have questioned the lower than N During the awards and then north to five points. From there it was a short distanceChute or sled, going by both names.

At the base of the slide is a stream corridor. Respondents in the station early on the G193 and returned to the sled and questioned the whole line station G205. They reported a total of 1,563.8 feet, but seems to be 1738.10 m total absorption of THC is 10,311.77 feet

July 12, 1969 – Richard Schreiber and Della McGuffin returns the maximum current extracted from sledding and mapped only 262.74 meters range of the 2 MileMarket Cave John Petty. They may not know the actual distance mapped and continued for a whole day mapping.

The survey data first to the second mile is available in PDF format on my site caving.
