30 June

On 30 June 1908, the energy created by the impact of a meteor which later became known as the Tunguska Event caused the Great Divide to open in Russia, allowing some of the Charrl to enter that time period from 22,000. (PROSE: Birthright) The Third Doctor attempted to take Liz Shaw and Jo Grant to witness the meteor impact, but the TARDIS instead materialised in St. Petersburg in December 1916.
