[1] Cape Serdtse-Kamen is a geographic landmark, east of which the Chukchi Sea coast slants sharply to the southeast until the Bering Strait.

The wreck of the Soviet steamer Chelyuskin, which sank in 1934 during its pioneer exploration of the Northern Sea Route, was discovered in 2006 on the seabed at the depth of about 50 m not far from the cape.

[2] The village of Uelen, the easternmost settlement in Russia, is located 150 km to the southeast of Cape Serdtse-Kamen along the coastline.

The area around this headland is a natural habitat for the short-tailed albatross (Phoebastria albatrus).

[4] Very large numbers of walruses have been observed resting on shore and in the shallow waters adjacent to this cape during the late autumn.
