New discovery of impact crater in Alberta, Canada.

An 8 km wide crater has been found near Bow City in southern Alberta.

Ancient impact crater in Alberta

Sometime in the last 70 million years, it is very likely that a large meteorite caused a big crater, around 2 km deep.

Most of the rock has been eroded since then, leaving only the deepest part of the crater.

The discovery is reported in the journal ....'Meteorites and Planetary Science'.

This is interesting, because it makes it possible to see rocks right at the bottom of an impact structure.

These rocks have been affected by the forces of the event, and show how the shock changed the rocks and created complicated faults.
