Oe	0-5 cm | Sample S-202
	Very dark brown (10 YR 2/3). 0% gravel; abrupt, broken boundary. Many fine and very fine roots. Comprised of decomposed leaves and grasses.
Oa	5-9 cm | Sample S-203
	Black (10 YR 2/1). 0% gravel; abrupt, broken boundary. Many fine and very fine roots. Appears to be just a pocket of Oa material - likely derived from rodent tunneling activity.
