The gulf extends from Cape Chukchi on the north to Cape Navarin on the south, forming part of the Bering Sea.

The river, taking its rise in the Stanovoi mountains as the Ivashki or Ivachno, about 67°N latitude and 173°E longitude, flows through the Chukchi country, at first southwest and then east, and enters the Gulf of Anadyr after a course of about 500 miles. The country through which it passes is thinly populated, barren and desolate. For nine months of the year the ground is covered with snow. Reindeer, upon which the inhabitants subsist, are found in considerable numbers.

The town, formerly called Novo-Mariinsk, is the capital of Chukotka region.
