In the period 24th – 27th March 2021, team of two, explored Kolkina beyond its 2nd camp. As a result we have:
- new 200m surveyed parts
- rigged new 15m shaft
- re-rigged 65m climb
Overall, there is a new region with lots of potential for further progress. The new region starts at the top of a 65m climb, which was last climbed by a group of 3 speleologists.
