QUESTIONS
1. Why do you think there are petroglyphs in the bedrock, but not in the large standing rock?
2. Do you think there were other petroglyphs here that have been lost to erosion?
3. Estimate the length of the arrow found at GZ.
(Optional) Post a picture of yourself with the petroglyphs in the background.

Also known as the Hamilton Farm Petroglyphs, these are one of but 27 recorded indigenous petroglyphs in West Virginia. Unfortunately, they mostly seem to be on private land. The rock art designs were carved by early Native Americans on sandstone. There were 25 designs cataloged when they were inspected in 1961. These included: bear tracks, deer tracks, human footprints, a snail or spiral, human figures with upraised arms, and a "Spirit Otter." They are within an 18-foot square section of the stone, at an elevation of 1,460 feet. This Earthcache will bring you to some of the remaining petroglyphs to learn about the sandstone and geology behind native carvings.
What is a Petroglyph
Petroglyphs are ancient or historic carvings made into rock surfaces by removing part of the rock's exterior. They are created by chiseling, pecking, or abrading the rock with tools, leaving behind designs, symbols, or images. Petroglyphs have been used by various cultures worldwide to convey spiritual beliefs, record historical events, and express artistic endeavors. Unlike pictographs, which are painted on rock surfaces, petroglyphs are directly engraved into the substrate.
Why is Sandstone Great for Carvings
Sandstone is an ideal medium for carvings due to its unique geological properties. It is primarily composed of sand-sized mineral particles bound together by a natural cement, such as quartz or calcite. Sandstone’s relatively soft structure and uniform grain make it easy to carve while still providing durability to withstand environmental conditions over time. Additionally, the porosity of sandstone allows it to absorb moisture, but this feature also requires care to prevent erosion.
The homogeneity of sandstone’s composition allows carvers to create intricate designs with consistent effort. Furthermore, sandstone is widely available in many regions, making it a historically accessible material for ancient artisans.
Sandstone and Petroglyphs in West Virginia
West Virginia is home to a rich geological history and numerous examples of sandstone petroglyphs. The region’s sandstone formations, such as those in the Appalachian Plateau, provide a canvas for petroglyphs created by indigenous peoples. These carvings often include representations of animals, human figures, and abstract symbols, offering insights into the spiritual and cultural practices of early inhabitants.
Prominent sites in West Virginia include the "Paint Creek Petroglyphs" and "Salt Rock Petroglyphs," where sandstone carvings showcase both the artistry and storytelling traditions of Native American tribes. The abundance of sandstone in the area contributed to the preservation of these cultural artifacts, though many remain threatened by environmental and human impacts.
Preservation and Erosion Impacts of Petroglyphs
The preservation of sandstone petroglyphs is a complex challenge due to their susceptibility to natural and human-induced erosion. Environmental factors such as wind, water, freeze-thaw cycles, and biological growth (e.g., lichen and moss) gradually wear away the rock surface, potentially obliterating carvings over time.
Human activities, including vandalism, pollution, and unregulated tourism, exacerbate the degradation of these artifacts. Conservation efforts often involve protecting petroglyph sites from direct exposure to the elements, such as by constructing shelters or applying chemical treatments to stabilize the sandstone.
Educational initiatives also play a crucial role in preserving these cultural treasures. By raising awareness about the significance of petroglyphs and implementing protective legislation, it is possible to safeguard these irreplaceable records of human history for future generations.
