I’m not your thread’s OP but I want to know the same question (what were the seasons) because no, I don’t know how fast glaciers reach that height either. Nothing about that implies denial of the validity, it’s a question to help quantify the change. Varying 10ft between seasons means this is a massive change regardless of season. Varying 100ft, not so much. No, I don’t beleive it’d actually be 100fr of change in 6 months, but I could see it being more than 10ft.
