The archaeological works, which were carried out at the
grave of Tatyana and Vasily Pronchishchevs in the Ust-Olenek
settlement and at the site of the ancient Russian trade
settlement of the XVII century (discovered in 1999), were
completed. There was prepared a detailed report about the
research and field works carried out in 1999 and 2001.
S.A. Nikitin, a forensic expert, has reconstructed the
real lifetime portraits of Vasily and Tatyana Pronchishchevs.
The excavations of the remains of the ancient Russian
trade settlement indisputably indicated that it had appeared
in the XVII century. The settlement still existed at the
beginning of the XVIII century. A find of seal-rings confirms
the original hypothesis that official representatives of
the Yakut Administration lived here and consequently – ataman
The expedition carried out the explorations of the mouth
of the Khara-Ulakh River. There were not discovered any
traces of the expedition of Peter Lassenius. The cross,
indicated on the maps as “the grave of Peter Lassenius”
does not actually exist. The place, where it was standing
does not look like a grave. The modern depths of the Khara-Ulakh
River indicate that it was hardly probable that a ship with
a 1.5-meter draft could have come here. Evidently this region
has quite different hydrology. The question of the position
of the coastal line in 1735 requires additional investigations.
