Brad Rosenheim<p>Imbrication: overlapping of sediment layers, fish scales, roof tiles, etc.</p><p>After our intense afternoon thunderstorms here in Florida, the streets abound with evidence of the deluge. Even in a land as flat as a pancake, leaves serve as the sediment imbricated by the intense rain. They have a surface area to mass ratio that is likely higher than even most clay particles, and thus they can behave this way even with relatively low slope and flow velocity. Imbrication happens in unidirectional currents and the grains organize with their upstream end higher than their downstream edge. So, in the geologic record they show us direction of ancient flows. Although formed by different processes, ripples in actual sediment can also show us direction and magnitude of ancient unidirectional flows. </p><p>All pictures taken from an alley in my neighborhood after a dousing thunderstorm.</p><p><a href="https://en.m.wikipedia.org/wiki/Imbrication_(sedimentology)" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">en.m.wikipedia.org/wiki/Imbric</span><span class="invisible">ation_(sedimentology)</span></a></p><p><a href="https://climatejustice.social/tags/geology" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>geology</span></a><br><a href="https://climatejustice.social/tags/sediment" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>sediment</span></a><br><a href="https://climatejustice.social/tags/sedimentology" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>sedimentology</span></a><br><a href="https://climatejustice.social/tags/paleoclimatology" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>paleoclimatology</span></a></p>

It is officially called the <a href="https://kolektiva.social/tags/Batagay" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Batagay</span></a> (also spelled <a href="https://kolektiva.social/tags/Batagaika" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Batagaika</span></a>) crater or megaslump and formed when a portion of hillside in the <a href="https://kolektiva.social/tags/YanaUplands" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>YanaUplands</span></a> collapsed in the 1970s. </p><p>"However, the crater wasn't discovered until 1991, when satellite images revealed a rounded cliff face towering over a huge depression in the frigid landscape.</p><p>"The Batagay crater is the largest megaslump in the world, measuring 3,250 feet (990 meters) wide as of 2023. The cliff face at the top of the formation, or headwall, stands 180 feet (55 m) high.</p><p>"When it opened, the gateway exposed layers of permafrost that had been frozen for up to 650,000 years — the oldest permafrost in Siberia and the second-oldest in the world, after relict ground ice in <a href="https://kolektiva.social/tags/Canada" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Canada</span></a>'s <a href="https://kolektiva.social/tags/YukonTerritory" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>YukonTerritory</span></a> that is about 740,000 years old. Recently, researchers found that the gateway is expanding annually by about 35 million cubic feet (1 million cubic meters), with the depression sinking further into the ground and exposing new layers of ancient permafrost.</p><p>"The headwall of the gateway is also retreating at a rate of 40 feet (12 m) per year due to permafrost thaw, discharging massive amounts of ice and sediment into the crater, according to a 2024 study. Some of this melt material may remain in the crater, but <a href="https://kolektiva.social/tags/sediment" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>sediment</span></a> and ice also washes into the <a href="https://kolektiva.social/tags/BatagayRiver" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>BatagayRiver</span></a> valley at the far end of the gateway, researchers noted in the study.</p><p>"The permafrost in this region is 80% ice, which is likely why the hillside slumped in the first place, Thomas Opel, a paleoclimatologist at the Alfred Wegener Institute in Germany who has studied the gateway to the underworld, previously told Live Science.</p><p>"The gateway sits in a landscape of larch and birch <a href="https://kolektiva.social/tags/woodlands" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>woodlands</span></a> that became the target of <a href="https://kolektiva.social/tags/deforestation" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>deforestation</span></a> from the 1940s onward. Deforestation caused the <a href="https://kolektiva.social/tags/topsoil" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>topsoil</span></a> to rapidly erode and expose the underlying permafrost, which — due to its icy composition — melted more quickly than if it had been richer in sediments. Significant melting during the following decades caused the hillside to disintegrate and collapse, Opel said."</p><p>Read more:<br><a href="https://www.livescience.com/planet-earth/arctic/gateway-to-the-underworld-the-enormous-permafrost-megaslump-in-siberia-that-keeps-getting-bigger" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">livescience.com/planet-earth/a</span><span class="invisible">rctic/gateway-to-the-underworld-the-enormous-permafrost-megaslump-in-siberia-that-keeps-getting-bigger</span></a> </p><p><a href="https://kolektiva.social/tags/ClimateChange" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ClimateChange</span></a> <a href="https://kolektiva.social/tags/Underworld" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Underworld</span></a> <a href="https://kolektiva.social/tags/Methane" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Methane</span></a> <a href="https://kolektiva.social/tags/Melting" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Melting</span></a> <a href="https://kolektiva.social/tags/GlobalWarming" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>GlobalWarming</span></a> <a href="https://kolektiva.social/tags/ClimateCatastrophe" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ClimateCatastrophe</span></a></p>
