The area surrounding Lobelia, located in the Little Levels district of Pocahontas County, West Virginia, sits atop a vast "sinkhole plain" within the Greenbrier Karst region. This landscape is a labyrinth of limestone, home to some of the longest and most historically significant cave systems in North America.
1. The Friars Hole Cave System
Located just west of Lobelia on the western flank of Droop Mountain, this is the "crown jewel" of West Virginia speleology.1
Scale: It is the longest cave in West Virginia and the 7th longest in the United States, with over 52 miles of surveyed passages.
Discovery & Exploration: While known locally for generations, systematic exploration began in the 1960s. In 1976, cavers achieved a major breakthrough by connecting the Friars Hole Cave at the southern end with Snedegars Cave at the northern end.2
Geological Age: Some passages within this system are estimated to be over 4.1 million years old, formed by ancient streams sinking into the Mississippian Greenbrier Group limestone.3
2. Lobelia Saltpeter Cave
This smaller cave, now a protected preserve managed by the Southeastern Cave Conservancy (SCCi), holds immense local historical value.
Civil War History: Like many caves in the region, it was a vital source of saltpeter (potassium nitrate), a key ingredient in gunpowder.4 During the Civil War, the Confederacy operated mining works here to sustain their ammunition supplies.
Artifacts: The cave still contains rare archaeological evidence of this industry, including a saltpeter water collection trough and wooden hand tools left behind by 19th-century miners.5
3. The Hills-Bruffey Cave System
Located in the immediate vicinity of Lobelia, this system is a classic example of Appalachian karst hydrology.
Formation: It is formed by the "sinks" (where surface water disappears underground) of Hills Creek and Bruffey Creek.6
Historical Geography: The creek and cave system are named after early settlers like Patrick Bruffey. The area was once the site of the Bruffey’s Creek School (1910–1935), highlighting how the local community lived directly alongside these geological features.7
4. Peter M. Hauer and Spelean History
The history of these caves is inextricably linked to Peter M. Hauer, a legendary figure in American speleology.
The "KN03" Expert: Hauer was a preeminent historian of saltpeter mining (often signing his name as "KN03").
Lobelia Connection: In the early 1970s, Hauer left his teaching career to live on an old farm near Lobelia. From this base, he conducted extensive research into the historical use of West Virginia caves, contributing significantly to the National Speleological Society (NSS) and the preservation of the region's subterranean history.
Comparison of Major Nearby Systems
| Cave System | Known Length | Primary Historical Use | Status |
| Friars Hole | 52+ Miles | Scientific Study / Exploration | Private / Managed Entrances |
| Lobelia Saltpeter | Small | Civil War Powder Production | SCCi Preserve (Permit Required) |
| Hills-Bruffey | Several Miles | Hydrological Study | Private Property |
| Organ Cave (Nearby) | 45 Miles | Saltpeter / Fossil Site | National Natural Landmark |
Conservation Note: Most caves in this area are on private land or protected preserves. Because of White-Nose Syndrome (a disease affecting bat populations) and the fragile nature of saltpeter artifacts, access is often strictly controlled.

Mining for saltpeter (potassium nitrate) was a grueling, chemical-heavy industrial process often performed in total darkness. In the Lobelia Saltpeter Cave and others in Pocahontas County, the Confederacy relied on these "niter works" to bypass Union blockades.1
The techniques used were a mix of heavy manual labor and a multi-stage chemical extraction process.
1. The "Peter Monkey" Labor: Extraction2
The first stage was the physical removal of "petre-dirt"—cave soil rich in calcium nitrate (often from ancient bat guano).3
Excavation: Miners, nicknamed "peter monkeys," used mattocks and wooden shovels to dig out soil.4 They often had to crawl into tight "working bays" where the ceiling was low.
Evidence in Lobelia: You can still see mattock marks on the clay walls and tally marks (scratched lines) where workers kept count of the bags of dirt removed.
Lighting: They worked by the dim, smoky light of lard oil lamps or resinous pine torches, which left black soot stains on the cave ceilings that are still visible today.
2. Leaching: The Vats and Hoppers5
Once the dirt was collected, the nitrate had to be "washed" out of the soil.6
Hoppers: Large V-shaped or box-shaped wooden vats (hoppers) were constructed, often from rot-resistant white oak.7
The Process: Dirt was packed into the vats, and water was poured over the top.8 As the water filtered through, it dissolved the nitrates, creating a concentrated liquid called "mother liquor."9
Artifacts: In Lobelia Saltpeter Cave, the most significant remaining artifact is a wooden water collection trough, used to catch this nitrate-rich runoff as it drained from the bottom of the vats.10
3. Conversion: The "Ash" Chemistry11
The "mother liquor" collected was calcium nitrate, which is not yet gunpowder-ready. It had to be converted into potassium nitrate.12
Wood Ash: Miners leached water through common wood ashes (rich in potash/potassium hydroxide).13
The Reaction: They mixed the wood-ash water with the cave-dirt water.14 A chemical reaction occurred: the potassium from the ash swapped places with the calcium from the cave dirt, creating potassium nitrate (saltpeter).
Boiling: This mixture was hauled outside the cave to large iron kettles and boiled down.15 As the water evaporated, white saltpeter crystals formed.16
4. Supply Chains
Once purified, the "pure white gold" from Lobelia was packed into 200-pound sacks and shipped to major powder mills, most notably the Augusta Powder Works in Georgia.17 This operation was so efficient that Confederate soldiers famously remarked that while they often lacked food, they rarely lacked ammunition.
Key Historical Artifacts Found Near Lobelia
Hollowed Log Pipes: Used to transport water from cave streams to the vats.18
Wooden Hand Tools: Crude shovels and scrapers left behind when mines were abandoned or raided by Union cavalry.19
Ox Tracks: In some larger nearby caves like Greenville Saltpeter, you can still see the preserved hoof prints of oxen used to pull carts of dirt to the vats.
