Amazing Maze Cave Speleogenesis Studied By Geary Schindel FALL 2007 In 2006, the Texas Cave Management Association (TCMA) reached an agreement with the Texas Lands System (TLS) to manage their cave resources. Some of caves located on Texas Lands System holdings include O-9 Well and Amazing Maze Cave. Since the initiation of the agreement, TCMA representatives have repaired the gate at Amazing Maze and started to remap the cave. Amazing Maze has one of the densest collections of passages in the United States with more than 7,500 meters shown on the existing map, making it the third longest cave in the state.

TCMA By-Laws Revi sions Proposed By William Russell Photo by Aimee Beveridge The Bylaws of the TCMA are being revised for just to bring the bylaws up to date with changing times. Telephone meetings are changed to elec tronic meetings to allow for the use of email. The revisions to the bylaws are included in this issue of the Passages (see page 9) and the thinking behind the changes is discussed below. The TCMA mem bership must approve these revisions, which will be presented at the general membership meeting on and through its Board of Directors, but provisions brought before the meeting. Members meetings are primarily intended to elect the Board members who are then to govern the TCMA. To clarify this division of duties, the ability of members meetings to take independent action was limited [in sec See BY-LAWS p. 3
TCMA Passages Fall 2007 2 Organization. How do you get an organization organized? How do you translate good ideas and good intentions into reality? How do you get over zation and growth? What does any of that mean to having caves available to Texas cavers, saving caves, and preserving caves? TCMA held a weekend workshop for strategic planning last May. The Board began to answer the above questions and set goals to accomplish for the next two to ten years for TCMA. Seeing the vision is easy; developing a realistic plan for how to get to the vision is hard, hard work. But we developed some ideas and I believe you will start seeing some results. We have a new Communications Committee, with Kevin McGowan as it leader. Kevin needs your help. He is sending you a personal letter in this edition of Passages, and is especially concen trating on compiling pictures and video on all our caves so that the information can be used whenever needed. To make it easier to join, renew, or donate, we now can accept memberships or donations through PayPal. We have been talking about this for a long time, but it is now a reality. We are revising and restoring our ability to take monthly donations from any caver willing to make that commitment. Susan Souby has agreed to coordinate this effort, and we will begin accepting monthly donations through credit cards or electronic funds transfers this weekend. Monthly donations not only add to to improve our access to loans when we suddenly putting together information for a TCMA Listserve to provide membership and other interested people email news about TCMA projects, needs, and ini tiatives. We will take your email information if you want to be on the list, and will keep you informed. We anticipate sending no more than one or two emails a month.

The much historical information has been eliminated. The procedure for removal of Board members bers --the original word ing-is required to remove a Board member. With the increased size of the TCMA this provision is no longer useful, prompting much discussion.

The section on provisions were included elsewhere for the deliv ery of notices. A provision to elect a Chairperson it requires action by a majority of all members to remove a Board member. A Board member could be removed by calling a members meeting to re move the Board member. This would only require of the members are needed for a quorum. This has not been a pressing problem, but most orga nizations have such a provision to remove Board members to prevent the embarrassment of having to the TCMA, or wrote to a cave owner that the you unless you provide access to your cave, or attempted a kidnapping to obtain money to buy a cave; then we might need a provision to remove the Board member. One problem with a is that an angry Board is likely just to vote an offending Board member off the Board. I do not think it is a good idea to allow a majority of the Board just to instantly remove Board members. Could Board members sue the TCMA, claiming they had been illegally harmed? I suggested a bylaw amendment that provides a board member could be removed by a three-fourth majority of the Board, and this way the Board could take care of the problem. There probably should be nations to be delivered and passions to cool; but there was not time to work out the details. This issue is still to be resolved. The By-Laws revisions will be presented to the TCMA member ship for a vote at the Oct. 21st Membership Meeting See pg. 9 for a complete copy of all proposed revisions to the TCMA By-Laws. BY-LAWS (from p. 1) Bill Russell is the Chairman of the TCMA ByLaws and Structure Committee The Texas Cave Management Association is actively seeking out caves for purchase. If you are aware of any caves that you think are signicant in length and depth and are avail able for sale, contact a TCMA board member and theyll bring it to the attention of the Cave Acquisition Committee (Geary Schindel, Chair). Finding caves worth purchase, which are located on properties that are affordable to the TCMA is the trick. Hopefully, our persistence will pay off with future cave acquisitions.
TCMA Passages Fall 2007 4 The Villages of Western Oaks Karst Preserve is an area of about 20 acres with several caves and a sinkhole located in Southwest Austin, in a subdivision one block west of the Mopac express way. The area was set aside as a preserve during development of the neighborhood, and an annual Austin as allowed in the contract. The City said you cant do that; we refuse to accept the proper ty. Meanwhile, during dry years the water level in the wet pond seriously declined and the City said the neighborhood had to add makeup water. The TCMA warned the HOA not to accept the pond or New Hope to Break Deadlock over Village of Western Oaks Karst Preserve By William Russell assessment was placed on neighbor ing houses and apartments to pay for management and maintenance of the preserve. During construction there was an interim management agree ment between the City of Austin, the developer Lumbermans Investment Company (LIC) and Village of West ern Oaks Homeowners Association (HOA), and the TCMA. The idea behind this agreement was TCMA would take care of the caves, the HOA would collect the assessments, and the City would turn the property over the TCMA when the subdivision all the work in the preserve. Unfortu nately, the contract was not explicit, there was much confusion in writing the contract, and the Barton Springs Edwards Aquifer District (BSEACD) is actually listed as the recipient of the property. However, the BSEACD has zero interest in the property. But that is not the serious problem. As part of the initial enthu siasm over the karst preserve, LIC agreed to build a wet pond to improve the water quality. This pond was con structed, but then was found to leak. LIC said it was not their fault, it was discussion (for years), then LIC said are giving the property to the City of A work day was held at the Village of Western Oaks Karst Pre serve in early October.

5 TCMA Passages Fall 2007 Howdy! Last year I was voted on the board of TCMA. I have al ways felt TCMA to be a welcom ing and friendly organization with the cavers best interests at heart. Gone are the days of secret caving and secret caves. With the advent of the internet, cavers are in touch, more informed, and a more inclu sive than ever! The past year on the TCMA board has proven that I was recently elected to the committee. The goal of the committee is to trans form TCMA into a more professional and respon sive organization. Weve grown over the past few years and with it, so has our responsibility. Its a daunting yet exciting task. Our biggest and most urgent need is for you, our members, to help out in anyway you can. As chair TCMA. We might use them to make a proposal for grants or selling our services of property and cave management, or helping us to acquire more caves. We need visual, audio, and written materials on our properties. We are putting together brochures for Whirlpool Deep/Punkin Cave Preserve, and even a TCMA Poster. We would greatly appreciate any copies of still photos, video, or sound clips that you think really captures the caves and preserves. Also, if you have a particularly interesting trip report, wed love to read it. TCMA needs the support of our members, and hope that youll respond. Any materials you submit to TCMA will be given a copyright credit. All we ask is that we can use them to promote TCMA and its mission. of volunteering on resto trips. That experience gave me a great respect for cave conservation and also allowed me into some pretty incredible caves. munity I get it backand sometimes I get back ten fold! It is the great caves, great caving opportunities, and great people out there that makes it so much fun! TCMA needs its members to step up and help us, as an organization, to jump to the next level. We need your help and support to make that happen! A Letter from the Communications Committee By Kevin McGowan they would be libel for the water that leaked from the pond. The city was just looking for a way out and wanted to give the wet pond to the HOA, but they resisted. This impasse has continued for years, but recent activity gives some cause for hope. The city called a meeting that was mostly a restatement of the issues, but it resulted in talks between the HOA and TCMA that informally sorted out some of the problems. After reading the contract we agreed re luctantly that the karst preserve included the wet pond, and karst preserve assessments could be used to maintain the wet pond. The HOA has asked the TCMA to start some work on the preserve using the preserve assessments, and this could be the start of a working relation. We do not actually need the either the City or LIC; we can just manage the pre serve. This is not a good long-term solution, as ence on the HOA, but it is a start. And, several in is a silly spat, and should not be allow to continue; so the TCMA is planning to bring the issue before the City of Austin Environmental Board, to break the deadlock. And despite the politics, the TCMA is planning on a wonderful Austin Cave Day at the preserve on October 27. There will be booths and displays from several agencies and you can poke into two of the caves. If you are in the area stop by and visit the preserve. Kevin McGowan

As a result, the sinkhole has long been partially debrislot. The cave also is home to two federally listed endan gered species. This project, the restoration of the sink hole entrance by removal of cave, enhanced access, and improving the surface of the property. Over the past year, there have been seven work days, during which two ma jor portions of the project have been completed: the steps into the sinkhole and a fence around the sinkhole. The stairs follow a trench that was dug into the sinkhole in order to remove the debris trench, is was decided that it would be an easier and safer access into the sinkhole as well as providing a control lable conduit for water and organic material to enter the cave. The steps are a series of low stone walls that are eter gravel. Water can trickle down through the gravel and pass through conduits placed in the stone portion of the steps. This controls the speed sion and sediment deposition at the bottom. This project proved to be a major undertaking, requiring The most recent addition was a fence around the sinkhole. The 30-foot depth of the sinkhole poses a potential safety hazard and the sinkhole has also been the victim of dumping on several occa sions. This project was undertak en by Matthew Haas of San An tonio for his Eagle Scout project. His plan involved placement of wood posts around the sinkhole and then attaching a four-foot high no-climb fencing material. A gate was also placed on the backside of the sinkhole to allow for hoisting materials in and out of the cave in the future. Matthew acquired all the ma terials without any expense to TCMA and organized for a group of volunteers to attend the work day. This was coordinated with a standard TCMA work day and
7 TCMA Passages Fall 2007 We are now into our third year of ownership of Deep and Punkin Nature Preserve and there are a number of improvements to the property that have cent additions to the cabin include a larger refrig erator, the addition of a pressure tank and two hot water heaters, and the installation of a second stove for cooking. The pressure tank has vastly improved water pressure in the cabin and made the shower a great luxury after a hard day of caving on the prop erty. We upgraded the electric service to the cabin of the second stove. This has improved the use of the cabin for cooking during when larger groups use the property. Our neighbor has worked hard on the road by removing a number of large rocks and grading the road. This should improve our ability to get to the property. We have also purchased a number of steel beams which will be used to con for a screened in sleeping porch. When the porch cover is completed, the second stove will be moved to the back to create a new cooking area. There have been a number of trips to Deep Cave over the spring and summer. Most of the trips vis in the cave appears to be having minimal impact. Over Labor Day, we had about 20 people members to the property. While there were a number of trips into Deep Cave, the group also did a lot of work on the property including clearing of cedar along the western property line, cutting of cat claw, and clearing and moving the road to Punkin Cave. because of bats. Evening visits to the Punkin Cave half hour in duration. The bats have headed south for the winter and the cave is now open for visita tion.

TCMA Passages Fall 2007 8 unusual pattern of the cave attracted the attention of Dr. Alexander Klimchouk, director of the Ukrainian has been spending the year in the United States as the visiting scientist with the National Cave and Karst 2007 to attend a meeting on the Edwards Aquifer, he asked if he could also visit Amazing Maze Cave. a mapping trip that weekend and invited us along. We also brought Steven Bryant, an undergraduate student in geology at UTAustin. Dr. Klimchouk is internationally known for his work on the large gypsum maze caves in Ukraine, and also for his work in Georgia, as one of the leaders of the expedition that explored Krubera Cave, the deepest cave in the world. Dr. Klimchouk has written extensively on the formation of maze caves by a process called vertical transverse speleogenesis. The theory states that some maze caves, such as network mazes and spongework mazes are formed by groundwater moving vertically upward. When groundwater reaches an impermeable unit, it will move horizontally, dissolving large AMAZING MAZE (from p. 1) networks imprinted upon the controlling geologic factors, such as faults, fractures, or fossil beds. Caves formed by this process have some unique characteristics including copulas or holes in the ceiling, dead end passages, and characteristic maze patterns. Because these types of caves are formed by regional and deep seated (hypogene) groundwater sulfuric acid processes. Amazing Maze Cave shows clear evidence of having been formed by vertical transverse processes and Dr. Klimchouck took a number of photographs of the cave as examples of this process. Some of these photos appear in this Hydrogeological and Morphogenetic Perspective Institute. Amazing Maze Cave contains a number of unusual speleothems including calcite blisters, crusts, and some large gypsum deposits. In addition, Steven Bryant found a deposit of waxy red clay in mineral indicative of sulfuric acid speleogenesis. The mapping of Amazing Maze Cave continues to extend the limits of the cave and hopefully, reveal additional clues regarding its formation.
