This Sky Caught Everyone’s Attention!

Now we have a third view. Kim is certainly closer to the dramatic cloud gyrations than either Larry or Shane. She was atop Bluff Mountain leading another group of visitors. But the perspective is about the same. Assuming the clocks on all three cameras were set correctly, these rolling (or roiling?) formations lasted for at least 1-1/2 hours.
Any more ACC members out there with a 4th look?
PS: To assume all three photographers had their camera clocks synchronized is a big leap of faith.
