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

Last week we held a fantastic meeting of the science team for the Canadian Lunar Rover mission at at the Canadian Space Agency - Canada's first ever rover mission to the Moon! We made important progress on mission operations development, including a nigh time simulation #ToTheMoon #CdnSpace

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

Wrapping up a great few days of #fieldwork in eastern #Quebec at a potential new meteorite impact crater. Stay tuned for details of what we found - hint: the brutal field conditions were worth it 😉 #geology #impactcraters #fieldwork #science

For the geologists: introducing the finalists for today’s best outcrop! #fieldwork #geology

The less glamorous side of #fieldwork - after a promising start, we lost a drone & then the rain started. And the outcrops were, well, less than impressive! We returned soaked to the skin back to camp. But a dry sleeping bag feels like the best thing in the world 😊 #fieldwork #outdoors #camping

Enjoyed two days of adventures so far checking out a potential new meteorite impact crater 😀 Some of the most challenging terrain I’ve ever worked in, but stunning scenery. And cool rocks 😉 #fieldwork #geology #outdoors

Yesterday was an adventure, even by my standards! With no suitable beaches, the float plane dropped us off 50 m from the shore 🤪 #fieldwork #geology

Well, after 3 flights & a 3 hr drive I’ve made it to as far east in Quebec I’ve ever been: Havre-Saint-Pierre. Our stop off point where we’ll take a float plane north tomorrow #fieldwork #geology #adventure

It was great to wrap up #Kamestastin2025 with a visit to the Innu Nation’s Sheshatshui Youth Centre to talk about the #Moon #Artemis & our training at Kamestastin Lake 😀

Today was capstone day: an EVA traverse on the central uplift of the Kamestastin impact structure. Time to put all the training together! #Kamestastin2025 #geology #artemis #impactcraters #geology #fieldwork

Another great day at Kamestastin. A beach of impact breccias & melt rocks makes for an excellent analogue for the lunar regolith! #Kamestastin2025 #Artemis #geology #fieldwork

A fantastic day of #geology at Kamestastin Lake - investigating impactites (rocks produced by meteorite impact) from anorthosite target rocks = amazing analogue for the #Moon #Kamestastin2025

Our first full day of #geology training at Kamestastin Lake. A vista to behold: hiking up the eroded remnant of an impact melt pond with the central uplift in the middle of the lake behind us #Kamestastin2025 #Artemis #ToTheMoon

We made it! Our advance team from @westernu.ca and #NASA has arrived in Goose Bay #Labrador. We’ll spend a day here doing logistics and then it’s off to the Kamestastin Lake impact structure for field geology astronaut training #Kamestastin2025 #geology #Artemis
