Abstract

The Arroyo Seco, located in Pasadena CA, is a beautiful sight in nature full of riparian and dry woodlands with varying native and invasive plants and trees. The Arroyo Seco stretches from the San Gabriel mountains out to Pasadena and Altadena, totaling 8 miles long. Our research was conducted on arborglyphs, or tree carvings/writings found in the lower Arroyo Seco. Our group conducted this research on arborglyphs because they offer a window into the past of those who have previously traveled there, and give us an insight to the different walks of life that have ventured through this area and what they might have uncovered. We hypothesized that, regarding the trees located in our designated research area, arborglyphs are more commonly found on trees in the oak woodland on the east side as opposed to those in the lower riparian wetlands in the west. Our research supports our hypothesis, as 71.6% of the arborglyphs were found in the oak woodlands, while 28.3% were located in the wetlands. The actual arborglyphs were most commonly found on Laurel Sumac (Malosma Laurina) trees, with 30.1%, and Oak (Quercus) trees, with 24.5%. The most common kind of arborglyph that was found were names/numbers/symbols which made up 39.6%, the other two categories being miscellaneous carvings and green and white spray paint dots, making up 30.1% each. In total, there were 53 arborglyphs that we recorded. Our data helped us answer our question of what are the most common form of arborglyphs found and where are they most commonly seen. While more research on this topic must be conducted to further investigate this phenomenon, our data that was collected helped us answer the question of where the actual tree carvings are more likely to be found.
