best guess is frost heave caused a liner leak (or the other way around). Where on the support ie where the panels come together which sits next to the deep end has pushed in. Panels look straight, it's more like what I would guess to be braces? Slipped down the cove over the deepend. I think it's 52" pool deepend is about 7' deep. it's 28' round and sits about 2' out of the ground. Tempted to self excave and see if it's salvageable. Anyone have any advice? Think I may get lucky? It's still in amazing condtion for being 20+ years old. I do think If I go this route I will back fill with slurry mix .
