This large island was named by him after Stepan Innokentyevich Rastorguyev, an Imperial Russian Cossack officer accompanying him.

Toll sent Rastorguyev along with the former captain of ship Zarya, N. N. Kolomeitsev, on a long sledge trip with the mission of organizing coal depots for the Zarya on Kotelny Island and at Dikson, as well as to bring the mail of the expedition to Dudinka.

This mission helped to bring relief to Baron Toll in a difficult situation concerning his relationship with Captain Kolomeitsev.
