Jeff MunroeGreat 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. <a href="https://fediscience.org/tags/geology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#geology</a> <a href="https://fediscience.org/tags/utah" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#utah</a> <a href="https://fediscience.org/tags/Quaternary" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Quaternary</a>

Jeff MunroeFinal 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. <a href="https://fediscience.org/tags/geology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#geology</a> <a href="https://fediscience.org/tags/Quaternary" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Quaternary</a> <a href="https://fediscience.org/tags/Vermont" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Vermont</a> <a href="https://fediscience.org/tags/spring" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#spring</a> <a href="https://fediscience.org/tags/outside" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#outside</a>

Jeff MunroeStudents 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. <a href="https://fediscience.org/tags/geology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#geology</a> <a href="https://fediscience.org/tags/earthscience" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#earthscience</a> <a href="https://fediscience.org/tags/vermont" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#vermont</a> <a href="https://fediscience.org/tags/Quaternary" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Quaternary</a> <a href="https://fediscience.org/tags/outside" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#outside</a>

Jeff MunroeAfter 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.

Jeff Munroe<a href="https://fediscience.org/@DrEvanGowan" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@DrEvanGowan</a> 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. <a href="https://fediscience.org/tags/glaciers" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#glaciers</a> <a href="https://fediscience.org/tags/geology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#geology</a> <a href="https://fediscience.org/tags/quaternary" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#quaternary</a>

Joe MasonHello, I'm Joe Mason, new here this week. I'm in Geography at UW Madison, studying and teaching about <a href="https://mstdn.social/tags/geomorphology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#geomorphology</a>, <a href="https://mstdn.social/tags/soils" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#soils</a>, and <a href="https://mstdn.social/tags/Quaternary" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Quaternary</a> paleoenvironments in the Midwest, Great Plains, and northern China. I post about those topics, related science, geography of <a href="https://mstdn.social/tags/Wisconsin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Wisconsin</a>, and all kinds of other things that catch my interest. Grassland and forest photos, <a href="https://mstdn.social/tags/IceAgeTrail" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IceAgeTrail</a> stories, complaints about academia.

Dr Dan ShugarOne downside of migrating servers is that your posts disappear (at least mine did). So here's my <a href="https://fediscience.org/tags/introduction" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#introduction</a>! I am a <a href="https://fediscience.org/tags/geomorphologist" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#geomorphologist</a> at <a href="https://fediscience.org/tags/UCalgary" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#UCalgary</a>, focusing on rapid geological changes in high altitude & high latitude environments. In other words, I study <a href="https://fediscience.org/tags/geohazards" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#geohazards</a> and <a href="https://fediscience.org/tags/Quaternary" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Quaternary</a> environmental change in <a href="https://fediscience.org/tags/glacial" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#glacial</a> and alpine environments. I use variety of tools incl <a href="https://fediscience.org/tags/satellite" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#satellite</a> remote sensing & field mapping to understand how Earth changes shape on timescales of a few seconds to millennia.
