Julie Brigham-Grette presents Lake El’ gygytgyn Research – YouTube
Elgygytgyn Lake is in Siberia near the Arctic Ocean and Alaska. It is an impact crater that has never frozen during Ice Ages because the Ice Age glacier cover is VERY uneven just as super cold wave vortex events are very uneven though these follow a rigid, set pattern covering the same areas with glaciers every Ice Age. We see clearly from the above charts showing pollen levels that not only are the Ice Age/Interglaical events more violently opposite of each other, that this has been a gradual cooling off process with the highs getting slightly lower each cycle but the lows getting much, much colder each cycle.
