Silers Cave Management Plan


The Mid-Atlantic Karst Conservancy (MAKC) is a 501(c)3 non-profit organization incorporated in the state of Pennsylvania in 1997. The MAKC owns and leases several karst preserves in West Virginia and Pennsylvania. The MAKC was established by cavers to preserve and ensure access to caves. We acquire and manage caves and karst areas for conservation, scientific study, and recreational caving.

Charles and Victoria Airey own a tract of property near Hedgesville, WV that contains one gated cave, Silers Cave. The owners and the MAKC have a common goal to preserve, protect, and maintain access to this unique resource and wish to partner in the management of this property as it relates to the cave. This resource may contain biological inhabitants such as eastern woodrats, bats, salamanders, and invertebrates and may be of significant hydrogeological importance.


Silers Cave was a favorite among cavers from the Baltimore/Washington DC area and SE Pennsylvania region until the property changed hands which resulted in the cave being closed around 2009. Silers is a maze cave with a total length of almost 8500 feet. Sligo Grotto managed the cave for absentee owners consistently through the later part of the twentieth century and up until the change of ownership, whereupon the cave was closed to the public. The cave is gated and the gate has been modified over the years from what was initially a chain mounted manacle to the most recent bat-friendly steel gate that was installed in 2001.


The first known recorded trip into the cave occurred on February 25, 1940, when members of the NSS explored it after a member found it the previous summer. The group could not ascertain an official name for the cave, but it was on the property of a Mr. Siler and the locals called it “Siler’s Cave,” so the name stuck. An old ladder was found in the entrance pit, which “did not appear to be trustworthy,” so the cave had clearly been known and visited for some time. The NSS group explored and mapped for 3-4 hours and produced a draft map. At the time, it was the largest known cave in the WV Panhandle until Cricket Maze Cave was discovered in the mid-1980s.

Davies described Silers Cave in “Caverns of West Virginia” in 1965. An incomplete map drawn in 1948 accompanies the description. Davies mistakenly gives “Meyer’s Cave” as an alternate name. Meyer’s Cave is nearby, but is a different cave.

A 128-acre farm, containing the cave, was purchased by Mr. Robert Wyly in the mid-1900s for the recreational use of his family, presumably from Mr. Siler. None of the Wyly family ever lived on the property, although they visited frequently.

The cave entrance was bulldozed shut in the late 1960s, but the forces of nature conspired to reopen the cave by the late 1970s. The Panhandle Survey of the West Virginia Association for Speleological Studies noticed and took interest in the newly reopened cave and began remapping it. The landowner, increasingly annoyed at over visitation, nearly ended the survey and closed the cave again, but the Sligo Grotto intervened and was able to negotiate a management agreement to keep the cave open. Sligo’s agreement with Mr Wyly in late 1978 required that the grotto gate the cave, maintain the gate, and strictly limit access to two trips per month. The first gate was installed in April and May of 1979 and that agreement remained in place for almost 30 years.

In 2001 the Sligo and Baltimore Grottos, which had recently co-hosted a Virginia Region Meeting, financed the construction of a sturdy new bat-friendly gate inside the cave. That same year, Mr. Wyly was awarded the Virginia Region’s Landowner Appreciation Award for his decades of cooperation with cavers and his long-time support of caver management of his cave.

Only a couple years later, Mr. Wyly passed away. Since his grown children had no interest in the property, the family decided it was in their best interest to sell the entire property to developers. Extensive negotiation with the family and the developers to try to parcel out the cave proved fruitless, and cavers unfortunately lost control of the cave. After several years, and with no houses having been built, the developers went bankrupt and the lot containing Silers Cave was sold. The new owners closed the cave and eventually sealed it. The current owners purchased the property in October 2018 with the intent of reopening the cave to the caving community.


Silers is a maze cave developed just below the contact of the Keyser and Tonoloway limestones, with the Keyser generally forming the ceiling and the majority of passages being in the Tonoloway. The cave is located near the axis of an anticline, and dips gently to the east. The cave is geologically related to Cricket Maze Cave, located on the next hill to the south, which is also a maze cave whose major axis aligns with Silers along the anticline.

The cave is mostly developed on one level. Most of the cave is an irregular grid, with tall and wide major axis passages and smaller interconnecting crawl- and stoop-ways. The major axis of the cave follows the local uplifting, leaving nicely parallel passages and dips gently to the east. The cave contains some formations, although it is better known for its mud. A very fine slip fault can be seen in the aptly-named Fault Room. Passages are formed along joints lying N 60 degrees E, N 20 degrees E, and N 30 degrees W.


The first documented trip in 1940 noted “All parts of the cave contained bats of the Pepersilus family, which, though not present in any great number, were generally plentiful.” No other type of bat was seen. This and subsequent reports also describe a “great number of cave crickets.” Bats, salamanders, and cave spiders were also common.

In 1963 Dr. John Cooper collected two male amphipods in Silers Cave. Dr. David Culver documented these as a new species of amphipod in 1967. He named it Stygobromus cooperi Holsinger. This amphipod is considered unique to Silers Cave and has not been identified in any other cave system to date.

John Holsinger included this amphipod in his 1967 article “Systematics, speciation, and distribution of the subterranean amphipod genus Stygonectes (Gammaridae)” in the Bulletin of the United States National Museum, 259: 1-176. The amphipod was also mentioned in The Invertebrate Cave Fauna of West Virginia (West Virginia Speleological Survey, Bulletin 7).

Silers has never contained a great number of bats, but some could almost always be found. White Nose Syndrome (WNS) reached the area about the time the cave was closed to the public, so its effects are unknown. However, the previous owners physically sealed the cave no doubt to the detriment of the bat population. It will be of great interest to see if the bat population rebounds after the cave is reopened.


The NSS trip in 1940 produced a map drawn by Robert Coats. An article two years later tells of the party carrying this map. George Burhans, a Hagerstown, Maryland-area caver, produced another map a few years later, only a couple years before his untimely death in 1953.

The cave description in Davies (1965) was accompanied by an incomplete and unattributed map drawn in 1948, which is now known to have been completed by George Burhans.

The cave was surveyed from 1978-1980 by members of the Baltimore, York, DC, Sligo, and Pittsburgh Grottos, and a map was drawn in 1980 by Bob Gulden, giving its length as 7243 feet and vertical extent as 60 feet. Additional passage uncovered since then has brought the cave to a length approaching 8,500 feet.


Researchers are required to submit a preliminary report documenting initial findings, data, and project progress no later than 30 days after access to preserve. A final report is required within one year of completion of project. A schedule of reports for longer-term projects can be established if necessary. The owners reserve the right to comment upon published papers which might reveal sensitive information, and specifically prohibit publishing reports on the internet without their approval.


The MAKC board will designate a preserve management team to oversee the property. The board shall approve the team at the recommendation of the cave manager and one team member shall be named as the cave manager, subject to the owners’ approval. The cave manager shall report directly to the MAKC board of directors on all issues concerning the Silers Cave Preserve.


The MAKC seeks to publicize caves only as befits our mission as stated in our bylaws and constitution: for education of the public about caves and karst resources; for published scientific studies in cave-related publications, and depending on the sensitivity of the material, on the MAKC website ( Specific cave location information, such as directions to the cave, WILL NOT be released to the general public. The MAKC will seek to minimize publicity of cave locations.

The MAKC can use the cave names in publicizing acquisitions and in its newsletter, Karst Chronicle, and other caving publications, such as the NSS News, grotto newsletters, and the MAKC website. The management plan will be available for publication in these mediums mentioned above. Caving organizations publishing electronic forms of their newsletters should remove reference to the cave location in the electronic format/archive and may publish trip reports to the cave, where they are not widely available to members of the general public. Copies of published trip reports will be sent to MAKC at MAKC will send copies of reports referencing Silers Cave to the owners. Specific requests for publicity concerning the cave that are not covered under this policy should be approved by the owners, and the MAKC board of directors.


The MAKC has a lease agreement for Silers Cave only and has no responsibility for maintaining surface portions of the property.

The MAKC and the cave management team will focus on these areas:
1. Restore entrance to its natural opening and perform maintenance on entrance ladder.
2. Develop a plan for securing cave with updated gate or modifications as necessary.
3. Continue studies begun over decades ago on this cave, starting with a habitat inventory with focus on bats and amphipods. Since the cave has been physically sealed, monitor bat population over time to see if and how bats return.
4. Conducting cleanup trips as necessary and remove any graffiti and trash.
5. Develop a remedial plan to humanely address a raccoon cave population that has expanded during years since the cave was closed.
6. Update map by surveying passages currently not shown on most recent map of cave.
7. MAKC reserves the right to conduct conservation-related trips to the caves and property, over and above the monthly trip limit. 


Maintenance of the Silers Cave gate is the responsibility of the MAKC and its designee. Major gate repairs, gate vandalism, or a break-in to the cave will be reported to owners. Major instances such as those stated above will be corrected by the management team and repaired with the cooperation of the owners.

Maintenance to surface portions of the property is the responsibility of owners although MAKC and its management team will initially work with owners on providing support and resources for demolition and removal of certain structures and misc. trash that owners would like to be addressed. MAKC and its management team will also conduct annual work days to assist owners with keeping path to cave and parking area clear of brush and debris.


The MAKC, its board of directors, the management team, the property owners, the cave manger, the NSS or its local chapters (grottos) or any individual members thereof will not be liable for any damages, accidents, injuries, or death on the surface or subsurface of the property.
