Very nice trip report and pictures Sonny. That's an impressive climb without ropes.
Funny that you mention the difficulty of Warspite, was up there yesterday with Vern and Scott Berry and in dry conditions, as it is right now, I wouldn't even rate it difficult at all. After the col there is one step with some exposure but that's it. We didn't do the traverse to Invincible because I wasn't feeling to good (nasty stomach pain) and still want to go out tomorrow.
But the lake (or what's left of it) certainly stinks and when we were having a break in the valley above the cascades there were multiple parties looking for a lake. So that must be the "third" lake on the map then?
