In situ cosmogenic 10Be and 26Al reveal the complex exposure and erosion history of the landscape once covered by the Quebec-Labrador Ice Dome Abstract. The rate at which ice sheets erode rock and produce sediment is poorly known. Here, we use paired cosmogenic nuclides in both deglacial and modern sediment to understand better the efficacy ...

Guess what. Glaciers aren't as good at eroding the landscape as we might have thought. New paper with collaborators from Quebec, France, and across the US. Internationalism lives on at least in science!

After about 5 years (!) of keeping secrets, I am so excited that Disney Pixar's Hoppers is finally coming out on March 6th!

Back in 2021, Pixar emailed me asking if I could give a talk about my research to their employees. Then another talk. And another.

Extending the western Hudson Bay Lowland Quaternary stratigraphy, in Manitoba Canada, to at least Marine Isotope Stage 10 Quaternary stratigraphy can improve our understanding of glacial dynamics prior to the Last Glacial Maximum. This study uses a hybrid lithostratigraphy–allostratigraphy approach to decipher the strati...

Our new paper is out, in proper format, in CJES today. It's a continuation of our stratigraphic framework development in the southwest HBL, together with Paleo environment data (UofT) and optical dating (UFV).

Absolutely true - I am more and more aware every day of the need to question established 'common knowledge'.

Clever Cuttlefish Have Passed the Marshmallow Test | Hakai Magazine Cuttlefish show they can be patient and ignore a snack that’s right in front of them to hold out for a more tantalizing treat.

I also told students to me more like the cuttlefish - again, don't take the marshmallow because it is quick and easy and right in front of them

Interested in how accurate your surficial geology map is? I'm available for virtual University classroom lectures.

Parallel to ice flow? Could be push moraines or deGeer moraines if perpendicular, parallel.....very odd!

I've got one with very minor revisions sitting for 30 days without acceptance. Super annoying

I’m gonna miss the Permafrost Terminology Action Group of the Canadian Permafrost Association. Most of us made it to GeoManitoba 2025 for the Glossary launch and photo op πŸ™Œ #scicomm

Stopped the bike ride for a little geology. Fascinating mud cracks that peel off in layers, and sticky clay underneath. Little minds shocked and amazed when they learned that mud cracks are found as 'fossils' too. #geology

Congratulations to Mr. Mesich who successfully defended his MSc today at UWaterloo. It's been a pleasure serving as your co-supervisor with Dr. Ross.

Fire-induced rock spalling! This area burnt about 1-2 months ago. All of the little rock shards on the ground are spalled pieces of the granite boulder, overlying burnt soil and moss.

Before seeing this in person, I didn't really consider the mechanical weathering effects of fire!

Hazelnuts in their very hard shells - will be toasted, cracked and shelled, toasted again and turned into hazelnut butter.

Campground foraging near the Manitoba Escarpment. A lot of work for a little bit butter. Makes me grateful for farms and grocery stores.

Fair enough. The politics are complicated. I went in 2006 as an unaware MSc student.

It's a very eerie place. We disembarked and I remember the playground swings moving in the wind.

Prairie skies just after the storm. Also have the requisite train and crops.
