1 Depth sed [m]	2 Depth top [m]	3 Depth bot [m]	4 Soil comp	5 Comm 2	6 Comm 3
0.050	0.00	0.10	Fine-grained pale yellow polymict sands
0.350	0.10	0.60	Turf
1.175	0.60	1.75	Fine-grained, pale yellow horizontally undulated-laminated sands with a polymict-quartz composition. Lamination is determined by alternation of grey interlayers 0.3-1.5 cm thick enriched with organic matter and sand interlayers 1-12 cm thick.	The bottom portion contains ferrugination spots and interlayers. The contact with lower strata is clear, undulated and stressed with the ferrugination interlayer 0.4-2 cm thick.
1.825	1.75	1.90	Peat-sand alternation strata. The thickness of brown colored peat interlayers is 0.5-0.7 cm. The thickness of pale-yellow sand interlayers is 0.5-1.5 cm. The strata is broken by a vertical frost crack (with a visible thickness of 35 cm)	going deep to the lower lying strata. The crack is filled with fine-grained sand. Intense ferrugination is observed along the crack sides, the sides are irregular and lacerated. The crack width is 10-13 cm.	The vertical displacement along the crock of the northern and southern blocks comprises 7 cm.
2.250	1.90	2.60	Brown-colored well decomposed peat with lenses of fine-grained yellow colored sand
2.700	2.60	2.80	Ice is in layers. The layer sloping angle is 10o. The contact with the above lying strata is uniform and with the lower strata
3.250	2.80	3.70	Fine-grained yellowish-grey colored quarts sands with reddish ferrugination spots and streaks. The spots are elongated along the long axis from bottom to top.	At the contact with the lower strata, there is a thin ferrugination interlayer with a thickness of 0.3-0.4 cm.
3.950	3.70	4.20	Fine-grained pale-yellow undulated-horizontally-laminated sands. The character of the cryogenic structure is massive.
4.475	4.20	4.75	Fine-grained pale-yellow colored quartz undulated-horizontally-laminated sands. The strata contain the oblique ice veins with the sloping angles of 10°, 20°, 30° and 45°.	The thickness of ice veins increases downward the section comprising between 0.5 to 25 cm.
5.250	4.75	5.75	Fine-grained pale-yellow colored quartz undulated-horizontally-laminated sands with subvertical ice veins and veinlets 0.3 -5 cm thick.
30.100	24.20	36.00	Ice complex deposits represented by a laminated sandy peat-loam alternation strata broken by multiple ice veins. The visible vein width is up to 6 m.
