SOILS
Creation of a soil pit at site #3 was challenging due to the abundance of bedrock and glacial till. When completed, the soil pit displayed clear horizon development including the presence of O, A, E, and B horizons. The O horizon had a strong leaf litter presence and extended 3 centimeters in depth with a pH of 4.0. The A was a dark brown color and extended 6 centimeters in depth with a pH of 4.0. A distinct whitish-gray E horizon appeared below the A extending 9 centimeters with a pH of 4.5. Below the E, the B horizon was a bright reddish-brown and seemed to display both a B1 and B2 layer. The B extended 13 centimeters below the E with a pH of 4.5. The pit yielded soil of a sandy-loamy texture, meaning it is made up of between 0 and 20% clay.
