Cave Locations on the Internet

As anyone conservation minded will tell you, having a cave location be public knowledge is usually a recipe for disaster. It's a very well documented phenomena that people break cave formations, vandalize caves with spray paint and other mediums, and leave gross amounts of trash behind. Even well meaning hikers and outdoors people may not realize the nuance of landowner relations and by accessing private property may upset relationships that cavers have worked hard to develop so that we may have access to caves.

The proliferation of geodata in many accessible forms is eroding the secrecy that the caving community has long used to protect underground resources. Here's a guide with suggestions on how one can protect these sensitive places from occuring on Internet.






The first thing to realize about Google maps is that deleting a feature is nearly impossible. It's possible to "take ownership" of a feature if you claim it as a business, which involves recieving some mail from Google and plugging in some numbers they mail you. The easiest method I have found to manage a feature on Google Maps is as follows.

1) Locate the feature.


2) Suggest and edit.


3) Change name or other details.


4) Update location on map.



5) Select a location that is meaningful.
Here I have chosen a local city park, Ensor Sink. A small cave is located there, and there is an interpretive kiosk with information about caves, hydrology, and conservation. It's a well developed resource which has values consistent with that of the caving community.


6) Update the Website.
I have chosen to update the website for the feature to that of the National Speleological Society so that people interested in caves will be more easily connected with the community.






For this example I am going to use a feature on public lands, Lost Creek Cave. Because the location of this cave is so well known, and even publicised by its land manager, the State of Tennessee, I will not actually delete this feature from the map. This simple serves as an illustration on how one would remove a cave from OSM.

1) Log in
You will need to create an account with OSM if you do not already have one.

2) Locate the feature.


3) Select the feature by clicking on it.


4) Edit the feature.
Expand all attributes and use the trash can to delete feature name and any tags which exist.


5) Save your work. Click the save button in the upper right when you are done.

Standing Stone State Park and State Forest

For the purpose of this blog post I will be treating Standing Stone State Park and Standing Stone State Forest as a single entity. However, they are distinct, and are managed by different entities with different objectives. Both the State Park and State Forest are located entirely within Overton County, Tennessee about 10 miles northwest of the city of Livingston.

Standing Stone State Park

Standing Stone State Park is approximately 1000 acres surrounding Standing Stone Lake. It is itself surrounded by 8000 acres of State Forest of the same name. The park is a celebration of the efforts of the Civilian Conservation Corp (CCC). The large earthwork dam is made of hewn sandstone.



Being a State Park, this area is managed for recreation. Camping there is popular at their rustic cabins. Most people come for hiking trails, fishing, and for paddle boats or kayaking on the small lake.

Standing Stone State Forest

There seems to be a degree of confusion as to the meaning of a State Forest designation. Land management on State Forests often attract criticism due to this misunderstanding. Taken from their own website, this is their stated objective:

    The Tennessee Department of Agriculture Division of Forestry has been protecting, conserving, and enhancing our state’s forest resources for over 100 years. The Tennessee Division of Forestry extinguishes 1,000 fires that burn 20,000 acres each year and helps control the disease and insect pests that plague our forests. It provides professional, timely, up-to-date, science-based technical and financial assistance to family forest landowners, communities, non-government organizations, forest industry, and others with an interest in the conservation of Tennessee’s forests.

Further the criticism they often draw is due to clearcuts. This is what they have to say about that:

    Clearcutting is a forest regeneration technique that creates wide, open spaces with lots of sun exposure. This allows the most sunlight to reach tree seedlings that require full-sun conditions to thrive. Clearcutting also creates forest clearings that are habitat for various wildlife species.

Often, but not always the Division of Forestry shares some management responsibilities with Tennessee Wildlife Resources Agency (TWRA) and the State Forest will allow licensed hunting and fishing. This is the case at the Standing Stone State Forest. For questions on hunting seasons, please consult this Summary of Tennessee Hunting and Trapping Season Dates.

Geography & Geology

Standing Stone is nestled within the lower elevations of the Eastern Highland Rim and the upper elevations of the Nashville Basin, as defined by geologic context. Its landscape is defined by rolling to steep hills with few waterfalls and cliffs. The large natural area created by the publicly owned land is a refuge for wildlife, plants, and trees. In all seasons the area shows off the beauty of our region (my own personal favorite season to enjoy Standing Stone is the Spring).

Waterfalls

While Standing Stone isn't known for its waterfalls, there are a few noteworthy ones within the park and state forest.







Botany

Protection of such a large swath of land has made the wildflower seasons a delight. The sloping hills, with seeps of water at random locations all provide lots of microbiomes for different plant communities to thrive in. Additionally, karst microclimates provide places for plants with cooler preferences.

Geography

Window Cliffs State Natural Area is located on the Eastern Highland Rim of Tennessee. It is a few miles south of Cookeville, and within Putnam County. It is within the Upper Cumberland region of Tennessee, and within Middle Tennessee.

Cane Creek flows through the designated natural area before its confluence with the Falling Water River at Center Hill Lake.

Botany

In the valley alongside Cane Creek one can find abundant flowering patches of phacelia, phlox, and trilliums. Along the rocky ledges and cliffs watch for bright red flowers of columbine. In a few places you'll also see usnea clinging to dead trees and be reminded of Spanish moss.

Geology

Cliffs of Fort Payne Limestone atop steep slopes of Chattanooga Shale are the obvious geology throughout the park. The base of the valleys is Catheys-Leipers Limestone, but doesn't play a large roll in the story that one sees at the Window Cliffs.

In the above recreation of a map made by Hugh Mills, Larry Knox and students in 1984, one can see the distribution of the more brittle silicastone Fort Payne facies that is partially responsible for the arch formation.

Geomorphology

Natural Arches

The silicastone Fort Payne is topped a less brittle facies of limestone along the knife's edge ridge of where the arches are located. This "roof" allows for the brittle Fort Payne to weather away underneith, while still being in place. As the brittle Fort Payne receeds, it leave gaps with roofs, or natural arches.

The recession process is driven at least partially by the oxbow bend of Cane Creek some 80' below the cliffs and arches. The stream carries away sediment, which is replaced from above as slopes gently give way to time, or by the occasional flood and slope failure. As the angle of repose reaches its maximum more sediment is carried away, and more material from above replaces it.

Waterfalls

Oxbow Falls, Putnam County, Tennessee
Window Cliff Falls, located on Cane Creek, is a classic Fort Payne and Chattanooga Shale contact waterfall, which is very common throughout the region. The falls drop about 30' into a small, swimmable plunge pool. There was once a rope swing there, but I am unsure if it is present since the state took ownership of the land.

Other, nearby waterfalls are also formed at the Fort Payne and Chattanooga Shale contact. However, Oxbow Falls, pictured right is formed at a steep portion of the Fort Payne on an unnamed tributary of Cane Creek. It's an unusual area, but worth wandering off trail to see.

City Lake in Cookeville, Tennessee

City Lake is an articifial impoundment located near Cookeville's Eastlake subdivision. It is within property managed by the city of Cookeville as a park, named City Lake Natural Area.

While the history of City Lake in Cookeville is fascinating, I could never cover it as well as Jennie Ivey has. I will simply leave you with a brief explanation of the local geology.

The karst spring which feeds the waterfall is formed at the contact of the St. Louis and Warsaw Limestones (more about those types of waterfalls here). It is a type of geologic contact based waterfall that is seen throughout the region. Other places include Milligan Road spring, Piper Falls, High Hope Falls, and Peters Falls (all in White County, Tennessee). The reason for this is due to an abundance of chert acting as an aquatard either in the lower portion of the St. Louis, or upper portion of the Warsaw Limestone. This prevents water from moving vertically and forces its lateral flow downhill.

While City Lake Falls has one distinctive main spring, the entire geologic contact erupts with waterfalls during high water events. This suggests the possibility of other as of yet undiscovered conduits feeding to this location.

The lake below the waterfall, City Lake, is currently at the end of its life. Since its impoundment, sediment from the watershed above has slowly been making its way into the lake, and settling out. Sandbars have developed within the lake which are now growing grasses and shrubs. The transition between a lacustrine enrivonment and swamp is well underway. If this continues, it will disrupt some of the recreational uses of the park, like fishing and kayaking. As Jennie's article above mentions, there are those in the community who wish it to be dredged of sediments so that it can resume function as a lake.

Others in the local community, and those prefering a more enrivonmental agenda prefer to see that it be returned to its original environment and the dam removed. Dams fragment natural ecosystems and their removal restores the migration of animals, nutrients, and sediments within the riparian system.

An argument could be made for either side. Only time will tell how Cookeville chooses to manage this resource.
