Warspite-Invincible-Indefatigable-Gypsum traverse
21.5km with 2,125m gain in 11:15hrs car-to-car

Time splits as follows:
~3 hour ascent to Warspite
3:30hrs - traverse to Indefatigable (technical part; total time, with stops)
3:30hrs - bushwacking from Indefatigable East to Gypsum and parking after (even don't get me started which part was it; total time, with stops)
the rest - breaks at Warspite and both Indefatigable summits, plus moving from Indefatigable main to east peak.

I guess it easily can be the most technically difficult traverse I've done to the date. After it, Northover is just a cakewalk. Consider traverse to and from Invincible as Smuts to the 5th (or 10th) degree. I.e. it has multiple exposed climbs, and even more down climbs. On top of that, it's all loose. It might be a bit easier doing it in another direction, but I'm not sure about it.

Gypsum was a mistake. Simply not worth it. But, to bring the second car to the Lower Kananaskis Lake means waste at least 1-1.5 hour. A more optimal way is two groups moving toward each other (a radio communication is a huge benefit).
