After a flight of several hours from Krasnoyarsk, we arrived in Yakutsk to start a three weeks long expedition. However, the trip started on the wrong foot since our team was reduced due to a positive COVID test a few hours before the flight. Moreover, once in Yakutsk, plans were changing day by day due to the complicated situation of the wildfires in the region. The city was covered by a deep layer of smog, leading to delays and cancellations of flights for several days. However, despite the inconvenience, we manage to collect important wood material with the help of colleagues from the North-Eastern Federal University (Yakutsk).
