Illustration from Narrative of a Second Expedition to the Shores of the Polar Sea, in the Years 1825, 1826, and 1827

In the section the strata are represented much more inclined than they really are.

231 Fine-grained, nearly compact, yellowish-gray dolomite, forming the summit of the hill, but the first, or lowest stratum, in the language of geologists.

232 Compact, splintery dolomite, with a conchoidal fracture, and wax-yellow colour—second stratum.

233 A cherty dolomite; containing calc-spar—third stratum.

234 Bluish-gray dolomite, traversed by calc-spar—is nearly compact, and has an uneven, splintery fracture—forms the uppermost portion of the fourth stratum.

235 Talcose? limestone, having a curved slaty structure, and containing cherty portions—from the lower part of the fourth stratum.

236, 237 Earthy greenstone? forms the fifth stratum.

238 Brownish-red dolomite, with an uneven fracture; scarcely splintery. It has a compact structure, and is intersected by veins of calc-spar—from the sixth stratum.

239 Light yellowish gray dolomite, passing into chert—seventh stratum.

240, 241 Thin slaty beds of brownish-red dolomite, like 238—eighth stratum.

242 Bluish-white porcelain chert, sometimes mixed with red dolomite—243—ninth stratum.
