Mile 6 of Pettyjohn Cave is a force to the intense restrictions of the cave, The Outer Boundaries was pushed, then the discovery and study of the Discovery Place and up coming the study of Schreiber’s Extension.
The Discovery Area is currently the most northern place in the cave. Significant earlier mentioned the Emerald Pool and directly under Pigeon Mountain, it is the 2nd premier room in the cave. Two hundred and fifty ft long and about forty feet wide in locations with ceiling heights of near to twenty feet. The space ends with a large breakdown.
Schreiber’s Extension may possibly have been explored just before this study, and it is the longest extend of stream passage found so significantly. Reaching close to the edge of the mountain to the west and south, it is the minimum explored and understood portion of the cave.
February 22, 1974 – Richard Schreiber and Allen Padgett surveyed in The Labyrinth and on the first survey shot of 32 feet they surpassed the 5 Mile Mark. They ongoing unaware of the party and surveyed 585.89 ft T.H.C. Overall study now 26,969.69 feet.
May perhaps 26, 1974 – Richard Schreiber, Rod Price tag and Ted Wilson picked up the down stream passage out in the Outer Limitations and commenced surveying at station X38. They explored and surveyed practically to the decrease conclude of the Outer Limitations but at the decreased stream degree. To exit they had to loop back again up the stream to the junction, climb up to the upper stage and the cave south all over again. This is about a six spherical journey from the entrance!
The study resulted in 440.54 ft T.H.C. Overall study now 27,410.23 feet.
June 8, 1974 – Richard Schreiber and Gerald Moni caved out to the start off of Tobacco Highway and pushed an up stream passage. Note: There are two stations labeled W151, just one is at the significantly northwestern suggestion of the Outer Limitations and the other is at the start out of Tobacco Road. The June 8 survey was recorded in two unique study guides. The correct locale made use of on a map by Jeff Harris November 1990 and Richard Schreiber’s individual survey plot is at the end of the Outer Restrictions.
From the junction of station W65, Tobacco Road and Outer Limitations, they surveyed down to the stream level and related to the decreased degree of the Outer Restrictions. And then caved up the stream to the northwestern tip of the Outer Limits and pushed this passage one more two hundred feet.
The survey resulted in 732.90 feet T.H.C. Full study now 28,143.13 ft.
November 2, 1974 – Richard Schreiber and Ted Wilson did some mop up surveying in the Outer Boundaries. They prolonged the stream from the Outer Restrictions to a around siphon less than a hundred feet from wherever it emerges yet again.
The survey resulted in 430.01 ft T.H.C. Complete survey now 28,573.14 toes.
August 10, 1975 – Richard Schreiber, Marion Smith and a team from Massachusetts and Connecticut carried sections of a scaling pole to the Emerald Pool and Warren Heller climbed up but very little was gained.
August 23, 1981 – Richard Schreiber, Dwight Drennan, Wesley Sprunger, Pete Uberto and Keith Lynn returned to the Emerald Pool and bolted up the wall or employed a rope remaining from the pole climb. They uncovered the Discovery Room following climbing higher and a few limited squeezes.
The survey resulted in 409.23 toes T.H.C. Complete survey now 28,982.37 feet.
June 11, 1983 – Richard Schreiber, Wesley Sprunger and Pete Uberto started off the study of Schreiber’s Extension from station Z19 in the Squirrel Space. Found out by the very same team on April 30, 1983.
The study resulted in 1,400.59 toes T.H.C. Overall survey now 30,382.96 toes.
July 9, 1983 – Richard Schreiber, Keith Lynn, Wesley Sprunger and Pete Uberto returned to Schreiber’s Extension and continued the survey. On this study the cave was pushed beyond the most western limits to day as Schreiber’s Extension proceeds all over the facet of the mountain.
The survey resulted in 497.36 ft T.H.C. Whole survey now 30,880.32 feet.
August 13, 1983 – Richard Schreiber, Ed Strausser, Wesley Sprunger and Pete Uberto resumed the study, breaking the six mile mark at station ZA111.
Schreiber’s Extension is comprehensive of prospects largely heading up. The study adopted the stream stage and there are higher concentrations to be uncovered just about the entire length of the passage with several having been explored or surveyed. Schreiber’s notes are whole of feedback about potential customers and climbs up into higher concentrations. The subsequent mile will acquire us to the end of Schreiber’s Extension and 1 of people higher degrees.
The uncooked survey info for the sixth mile is readily available in pdf format on my caving website site.
