Gow crater

Gow crater is an impact structure in northern Saskatchewan formed by a meteorite strike, measuring approximately 5 kilometers across. A lake fills the crater's interior, with Calder Island rising from its center.

The crater formed less than 250 million years ago when a meteorite struck the area during the Triassic period or later. This impact created the distinctive geological formation visible today.

The site received its name in memory of James Richard Gow, a Canadian soldier who lost his life during World War II in 1945.

The lake supports fishing with populations of pike, trout, and whitefish available to anglers throughout the year. Visitors should prepare for the remote location and bring appropriate gear for exploring the crater landscape.

This is the smallest known impact structure in Canada featuring an uplift formation in its center. The rock formations here occur nowhere else on Earth.
