I'm Still Wondering,
Last summer a poster on here mentioned he was at the south end of Last Mountain Lake , which dropped four feet, then rose eight, and he could measure this by his dock. Entirely credible, I think this happened and I'm still wondering what caused this. I went out to the U of R and spent an afternoon wandering the hallways of the geology/geography departments, they found the story interesting, but mostly they were as puzzled as me. I'm not a geologist or a geographer, but it is a hobby of mine, particularly when it concerns Saskatchewan. The concept of an eight foot wave roaring down LML is mind-boggling to me. Do you know how large that lake is? You can see it in satellite photos, its the appendix scar on Saskatchewan, its a big lake. Its a mile wide and 70 miles long, its over 100 feet deep in places, its the scar left by an ancient glacier. For something to buckle a wave eight foot wave to roll down the lake, that's a significant earth event.
So what was it? I'm thinking uplift across the middle of the lake, although I cannot think of a mechanism to do this, or a general uplift of the entire northern end of the lake. That would be obvious, there would me miles of dead mud at the north end. I wish I had driven the lake soon after to look for evidence. But that's a pretty big bathtub sloshing around on the prairies. Yet another mystery.
