Through rain & sun the #SudburyImpact field school continues with the students working in groups to map & document shatter cones around the Sudbury impact structure #geology #fieldwork @westernu.ca

The afternoon continued by looking at the Onaping Formation breccias that overlie the melt sheet and then the post-impact sedimentary fill. Lots of cool rocks! #SudburyImpact #ImpactEarth

Enjoying a beautiful morning looking at the #geology of the Sudbury impact structure: beginning in the crater floor with pseudotachylite & working our way upwards through the 3 km think impact melt sheet! #SudburyImpact @westernu.ca

After a morning of lectures and hand sample exercises, we headed out in to field for an introduction to Sudbury #geology

Good to be back in Sudbury to teach my impact cratering short course and field school. What better place to teach than a 200 km diameter meteorite impact structure! #impactcraters #SudburyImpact #Apollo #Artemis @westernu.ca
