Oi	0-11 cm | Sample S-226
	Strong brown (7.5 YR 4/6). 0% gravel; abrupt, smooth boundary. Composed mainly of Sphagnum moss. Weak, platy structure due to compression of organic materials.
Oe	11-21 cm | Sample S-227
	Very dark brown (7.5 YR 2/4). 0% gravel; abrupt, smooth boundary. Weak, platy structure due to compression. Many very fine roots.
