a) The first assumption – the Camp was located at the
b) The second assumption – the Camp was located at the

- With the help of the Administration of the Bulunsky
Ulus to question local citizens, firstly hunters and fishermen.
- To investigate the archives of the hydrographic service
and the State Committee of cartography.
- To consult with geologists, hydrologists and climatologists
about a possible change of sea level and a hydrological
regime in the Khara-Ulakh River.
- To study the sailing directions of the Laptev Sea in
order to define all high rocks, looking like the Cape.
- To establish contacts with the scientists of local
lore from the town of Tula, who in 1975 erected a monument
to Lassenius at the Cape Khara-Ulakh.
- To study a toponymy of the area of the Buor-Ulakh Bay.
