"In the beginning of the century, simultaneously with a spring fair for the Reindeer Koryak, was established another one for the southwestern Chukchee on the Parapolsky Dol, not far from the upper part of the river Opuka" (1-080). The same page later prices "the Chukchee fair on the Opuka River" at no more than a few thousand rubles a year — read here as this fair, the only one the book puts on the Opuka, though the two sentences do not name each other.

Filed under Chukotka and not Parapolsky Dol, though 1-080 says "on the Parapolsky Dol". The point is some 2.6° east of the Dol and about the same distance west of the head of the Opuka: the fair sits between the two and inside neither, so it hangs from the region that does contain it.

What is uncertain is the identity, not the position. The coordinate above is the editor's reading of Bogoras's own map, between Parapolsky Dol and the head of the Opuka and near enough to both for the sentence above to describe it. What the map's label names is the open question — this entry reads it as the Opuka fair, and no page says so in those words.

"Chukchee fair" is not always this. 1-078 uses the phrase of the Anui fair — "The Chukchee fair was held at Fort Anuisk" — which is Ostrovnoye, not this.
