What did Beringia look like in the last “ice-age?” Alistair Monteath et al.¹ have just published an impressive review article!
I will need some time to read through it.
The more detailed fossil-based understanding of vegetation and soil is really important for a clearer picture of the plant–herbivore interactions. In the end, it’s so much more complex than the naïve concept of a homogenous mammoth steppe grassland…

“A storm as ferocious as the one of 12,350 BC would likely cause complete mayhem if it were to strike Earth and its surrounding space today..."

Great field trip stop with a view of the 21,000-year old left lateral moraine from the Little Cottonwood Canyon glacier cut by multiple strands of the Wasatch Fault. #geology #utah #Quaternary

Final lab of the semester for my Quaternary Geology class was a sporting one: fording the river and digging out a nice exposure of 14,000-year-old varves from proglacial Lake Vermont. #geology #Quaternary #Vermont #spring #outside

Students in my Quaternary Geology course came at this exposure from the bottom up, and the top down -- a curious sequence of basal till overlain by silty lake sediments deformed by a later glacial readvance. #geology #earthscience #vermont #Quaternary #outside

After gaining experience at a fairly straightforward site, students in my Quaternary Geology course have moved on to more complicated exposures. This one here reveals basal till beneath proximal subaqueous outwash that was deformed by a readvance. Great stuff! #vermont #geology #EarthScience #glacial #Quaternary #outside

Students in my #quaternary #geology course retrieved a sediment core from a local lake and analyzed it in the lab. They've produced an impressive dataset to support an environmental reconstruction spanning the past few centuries. Nice to have such solid #ice this #winter! #vermont #fieldwork #EnvironmentalScience #EarthSciences

@DrEvanGowan I had a similar thought when looking at the ages and the materials that were dated. Nonetheless, it's fun that there can still be such debate over a thousand-km difference in the position of the ice margin! I'll be interested to see the new data from Manitoba. #glaciers #geology #quaternary

I have been involved in a very exciting project over the last 3 years working with archaeologists from the universities of Stavanger and Bergen examining the likely consequences of the #Storegga #Tsunami on coastal communities in Norway over 8000 years ago. We model the Storegga #landslide and generated tsunami and the inundation at high-resolution at multiple sites along the coast of Norway.

I'm a #Quaternary geologist with a PhD from the #uwmadison studying #dust, #glaciers, #caves, #soil, #permafrost and other topics related to climate and landscape evolution in the mountains.

Hello everyone!
New here; escaping the hellscape of Twitter.

Here is a short intro. I'm Kaja a #Quaternary Scientist based at University of Liverpool.
I work on:
• developing #chronology using #luminescence dating (#OSL)
• understanding sediment #provenance using #geochemistry
• #dust records of environmental change (#loess)

I also bake, climb, hike, row, and absolutely love rocks

Hello, I'm Joe Mason, new here this week. I'm in Geography at UW Madison, studying and teaching about #geomorphology, #soils, and #Quaternary paleoenvironments in the Midwest, Great Plains, and northern China. I post about those topics, related science, geography of #Wisconsin, and all kinds of other things that catch my interest. Grassland and forest photos, #IceAgeTrail stories, complaints about academia.

One downside of migrating servers is that your posts disappear (at least mine did). So here's my #introduction! I am a #geomorphologist at #UCalgary, focusing on rapid geological changes in high altitude & high latitude environments. In other words, I study #geohazards and #Quaternary environmental change in #glacial and alpine environments. I use variety of tools incl #satellite remote sensing & field mapping to understand how Earth changes shape on timescales of a few seconds to millennia.
