Large boulder the size of a small boulder resting nicely on glaciolacustrine silt.
Always good to keep in mind that it does not matter how the fire starts. Fires start all the time, but what really matters is the high heat and low humidity to dry out fuels causing the fire to spread rapidly. And these conditions are increasing every year with anthropogenic climate change.

Laurentide ice sheet dynamics across multiple glacial–interglacial cycles from Quaternary stratigraphic records in central Canada
Quaternary terrestrial stratigraphic records are key to understanding the long-term behaviour of past ice sheets beyond the most recent glaciation. Glacial sediments provide important information on i...

Scott Kehler 🇨🇦@scottdkehler.bsky.social · 2mo agoToday is the most dangerous severe weather setup I have seen in southern Manitoba in a long time. Storms could produce tornadoes, destructive winds, and very large hail. If thunderstorms approach, take shelter immediately. #mbstorm
A century of geological mapping, research, and discovery. We are seeking submissions for a collection celebrating 100 years of Manitoba geology and the legacy of the Manitoba Geological Survey 🏔️▶️ https://ow.ly/vtvE50Z5a2s #Geology #EarthScience
CANQUA in Montreal was a great meeting of Quaternary scientists working in Canada and abroad. It was great to be able to present results from my PhD and further discuss on-going studies in Manitoba, such as this poster based on work in southeastern Manitoba.
It’s always fascinating to find whole valves of marine specimens in till - a relatively common occurrence in the HBL. I’m sure this Macoma calcarea has had quite the ride. Glaciers are often perceived as these ‘grinding’ machines, but on a soft substrate this is less true.
The Manitoba Geological Survey turns 100 in 2028. To mark this milestone, we invite invites submissions for a collection celebrating a century of geological science in Manitoba ▶️ https://ow.ly/tSM550Z59Qc #Geology #EarthScience #GAC-MAC
An exciting time for the survey here!

Captured this at the Winnipeg zoo the other day. Everyone needs a good Polar Bear snuggle these days.
We talkin’ bout sand!!! Have to love the versatility of sand. Here is some interglacial sand overlain by till deposited during the Wisconsinan advance, Churchill River, HBL.
If we want to have civilized conversations, then we need portray facts accurately. There are a number of things wrong with the Wpg Sun article today re: the Pandemic. The worst one is using conclusions and stats from a clearly withdrawn article. Do better @winnipegsun.bsky.social.
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).

I made a grave error and bought a ‘3D puzzle’ rated 4+ for the kids. This horrific creation is impossible. Each piece changes. Whole thing makes me dizzy but we are committed at this point.
I enjoy finding these relatively old literature comments.
It definitely piqued my interest to see Clark et al's reconstruction of sea level for the past 4.5 million years, something I first heard about several years ago. However, upon reading it, I am very surprised that this was published. 🧵 1/11 doi.org/10.1126/scie...

Changes in global mean sea level (GMSL) during the late Cenozoic remain uncertain. We use a reconstruction of changes in δ18O of seawater to reconstruct GMSL since 4.5 million years ago (Ma) that acco...

Yes, we get a lot of “is this a meteorite?” inquiries at the survey. Most often, the rocks are obviously not meteorites. However today someone strolled in with this material. This is by far the densest material that I have ever held. It puts a typical VMS Ni-Cu ore to shame. Anyone?
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. *Quaternary stratigraphy of the Gods and Yakaw river areas, northeastern Manitoba*
This also surprised me quite a bit. Was observed all over the area to some degree. May need a ‘wildfire’ parameter on your Boreal cosmo ages! Hah
Michelle Gauthier@mtrommelen.bsky.social · 11mo agoFire-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!
Sometimes you see the full scope of the chaos, then wonder what type of stories geologist made up when they could only see parts of said story.

July was the smokiest month on record in Winnipeg with 189 hours of smoke at the Airport. Temperatures were average, but it was much drier than normal. It was also the driest January to July on record at the Airport with 126mm of precip. Normal is close to 300mm
