Bald Friar Petroglyphs- Maryland's Forgotten Rock Art
By Julie Flynn, MAC Lab Petroglyph Project Conservator
The Bald Friar petroglyphs are one of the foremost examples of Native American rock art on the eastern coast of the United States. These petroglyphs were located on several small islands on the Susquehanna River, 3 miles south of the Maryland and Pennsylvania state line (Lenik 2009). Although records of this rock art date back to the 1600s, the creators of the carvings are unknown, both their time period as well as their tribe (Nevin 2013). At this point, the petroglyphs cannot be translated but there are five types of symbols commonly occurring: parallel lines, cups and cup groupings, circles and circle compositions, diamond compositions, and complex curvilinear compositions (Hall 2014). There is the occasional easily recognizable symbol (fish, heart, sun, etc.), but the meaning of the entire stone composition remains unclear. Did the rock carvings warn travelers of dangers in the river? Where to hunt? Directions? Or was it simply a narrative? While archaeologists pondered these questions, these petroglyphs were in danger of being obscured and forgotten by history.
The Bald Friar Petroglyphs are a unique example of destroying a monument to preserve it for future generations. The construction of the Conowingo Dam in northern Maryland threatened to completely obscure the petroglyphs and leave them to be forgotten by history. The dam caused the water levels surrounding Bald Friar to rise 30 feet and submerge the islands (Lenik 2009). Luckily, at this time, academic and public curiosity about these carvings was at a peak and a decision was made to remove the petroglyphs from the cliffs. Unfortunately, the way chosen to remove the petroglyphs from cliffs in the 1926 was with explosives (Hall 2014). In 1927, after the stones were removed from the cliff in this manner, they were reassembled into 90 stones and displayed on cement and brick plinths at the Maryland Academy of Science in Baltimore, MD (Lenik 2009).
When the Maryland Academy of Science moved to a smaller location in 1944, most of these stones were moved to the parking lot of Druid Hill Park and forgotten (Hall 2014). In the summer of 2017, a project began to survey all known Bald Friar petroglyphs in Maryland. Out of 226 petroglyphs from Bald Friar, 197 of the stones were at the Maryland Archaeological Conservation Laboratory. These petroglyphs were brought inside, cleaned, photographed, and documented. While not all of the stones contained carved glyphs, there were 78 stones with clearly distinguishable glyphs. These glyphs are not always very easy to see in condition photographs so different photography techniques were used to emphasize the carved areas. By taking several photos of the stone with one light source shining around the stones at oblique angles, it is possible to combine the photos to exaggerate the shadows within the carved depressions in the stone. When this new photo is converted to black and white, it is a stark improvement to the normal glyph visibility.
All the petroglyphs in the MAC Lab are now cleaned and in storage. The condition, measurements, glyph type and variability, and rock type have been recorded for each stone. These stones can now be more accessible for research. The conditions have been made to begin the conservation treatment of these stones. The stone treatments will largely include removing modern brick and cement from the stones to improve appearance and decrease the size and weight of the petroglyphs. These stones have been through a tumultuous journey over the last hundred years and hopefully, through this survey and future conservation treatment, they will be available to be studied and interpreted once again.
