The main expedition’s results.

1. 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.
2. S.A. Nikitin, a forensic expert, has reconstructed the real lifetime portraits of Vasily and Tatyana Pronchishchevs.
3. 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 Semyen Dezhnev.
4. 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.
