101000 Foot Pit in ChihuahuaThis report of a 1000 foot plus pit in Chihuahua was brought to theattention of Donald Davis by Jon Haman. Davis sent it to Frank Binney whereit was found by Barbara Vinson who passed it on to the AMCS. It is part ofan article in the American Institute of Mining and Metallurgical Engineers(Technical Publication n 154. Walker, R.T. "Deposition of are in Pre-ExistingLimestone Caves," issued with Mining and Metallurgy, November, 1928). Thearticle is discussing an ore chimney in the Potosi mine at Santa Eulalia,Chihuahua. As an afterthought, they mention "A few hundred feet distant fromthis orebody the limestone strata are penetrated by a large open chimneycave, over 100 ft. in diameter, which is reported to extend from the volcaniccapping near the 600 ft. level to the 1600 ft. level, and for an unknowndistance below. It is doubtless the conduit of an extinct hot spring, formedafter the mineralization of the district took place, since it contains no oreminerals, except in a few places where there are small earthy deposits ofmonheimite, the brick-red zinc-iron carbonate, which have obviously been derivedby migration from the oxidized portion of the near-by Potosi ore chimney.It is a suggestive circumstance that this postmineral chimney cave isof such shape that if it were completely filled with ore by ascending mineralizingsolutions, which would also replace the walls to some extent, theresulting orebody would be structurally indistinguishable from the Potosichimney. Further evidence as to the probable cave origin of the Potosi chimneyis afforded by the fact that in the neighboring San Toy mine an orebodyin the shape of a horizontal pipe, but doubtless formed during the same periodof mineralization, exhibits cave breccia of apparently premineral character."Dr. Robert !'litchell of Texas Tech University has received a grant from theNational Geographic Society to continue his and James Reddell's biologicalstudy of the cave life of the Yucatan peninsula. They plan to work in Yucatanthis summer and can be reached %James Reddell, Lista de Correos, Merida, Yucatan.Any cavers who plan to visit the area should write in advance of their trip.Just received a letter from Frank Binney, Inside Earth editor and notedspeleoadventurer, that he is going to far distant lands to film the Britishattempt to find the world's deepest cave. With a little effort, AMCS membersshould be able to find a deeper cave in ~~xico. It is perhaps all right thatso far the French have explored the deepest caves, as they live there, but theBritish? This summer all AMes members can help restore the national honor, beatthe British, and embarrass Frank Binney by finding a mile deep cave in Mexico.Everyone should receive a membership card with this issue. Some were sentout with the first issue, but no records were kept, so everyone gets a card thistime.
Cave Map Symbols11On the following pages are three sets of cave map symbols: the set byJames Hedges now being distributed by the NSS office, followed by the AMCS setof symbols and the set of symbols used by Ernst Kastning, a caver active in NewYork, but with considerable experience elsewhere. Other commonly seen sets ofsymbols are those used by the Cave Research Group and the symbols used in MissouriSpeleology. James Hedges has submitted a set of symbols to the NSS to beadopted as the NSS standard cave map symbols, but unfortunately this list is notavailable as it is so long he has not been able to prepare copies, but the maindifference between the list given and Hedges' revised list are covered in thediscussion.Cave map symbols should enable the priRted map to convey as much informationas possible about the three dimensional cave in a limited space. The set of symbolsshould be complete, so that all common features have a unique symbol, andblank paper indicates only lack of data. The set should be versatile so a fewsymbols can be combined to indicate most of the features found in the cave, andthey should be easily used by persons of little artistic ability.The advantages of a standard set of symbols are so overwhelming that itwould seem that a nationwide system would long ago have been established. Thereare several reasons why this has not been done. The first is that most mappingis primarily for local consumption. The local caver provides the vast majorityof all persons actively interested in a cave map and they know the local set ofsymbols, so the map is useful to them. This localism is being weakened as caversincreasingly visit distant areas and feel more a part of national and internationalcaving organizations. Inertia is another reason why a standard set of symbolshas not been adopted. Once a region or a survey has used a set of symbols to drawnumerous maps they do not want to learn a new set and make the old mappinp. obsolete.However, as most surveys and regions will admit that a common set of symbolswill someday be adopted, the sooner the change is made the fewer maps willhave been drafted using an eventually obsolete set of symbols. The need for acommon set of symbols has not been obvious to many non-mapping cavers as mostcave maps, especially those published in journals of wide circulation, are drawnto such a scale that only the general outlines of a cave can be given and nospecial symbols are necessary. Hm.,ever, the relative decline in the cost of printingin relation to the cost of living has made it possible to print more largecave maps that use special symbols extensively, and many of these maps are attainingwide circulation. As the student of speleology travels from Canada to tfuxicoand attends a conference in Yugoslavia he encounters a bewildering variety ofspecial symbols and local notations. Standardization has been taking place slowlythrough communication and personal contact, but the adoption of a standard setof symbols by the ~SS will set the trend for the entire North American continentand should be carefully considered.[2]1Simbolos:@][E]E§J~GJ[2]~023 t. 5 6 7 B 91. pared de La cueva. 2. doL Ina . 3. estaLoctltos etc. 4. gours . 5. derrumbes:6.tlerro. 7.c!iocLoso; 8. pendienle abruplo. 9.pendlente.Cuban Cave Hap Symbols
