Horizon:	Description:
Oi	0-7 cm | Sample S-166
	Dark yellow-brown (10 YR 3/6). 0% gravel; abrupt, smooth boundary. Composed of Sphagnum moss.
Oa1	7-14 cm | Sample S-167
	Dark brown (10 YR 3/3). 0% gravel; abrupt, smooth boundary. Many very fine and fine roots. Medium roots common. This layer is very silty, as if a flood event deposited silt all at once.

	Very dark brown (10 YR 2/2). 0% gravel; abrupt, smooth boundary. Many fine and very fine roots. Medium roots common.
Bw	33-51+ cm | Sample S-169
	Dark brown (10 YR 3/3). Weak, very fine, granular structure with 0% gravel. Sticky, plastic consistence (wet). Silty clay loam texture. Many very fine roots and common fine roots.
Permafrost	51 cm |
