Excellent explanation and use of visuals, especially the Google Air shot of the caldera that you color-coded for the various pyroclastic flows. Thank you so much for making this caldera “real”. Amazing geology.
Yeah i’m Going with that the second eruption that blew out the lake, happened generally around the same time. And was more of a lower pressure steady acid flow, after the erupting pressure broke down the SW wall. Then carved a canyon from the SW wall down to the Valley stemming from it. The blobs in the middle look to be the main thrust points of break through pressure. Then the semi circle of smaller pop up Volcanos, look to be lower pressured pop ups that pointed combined pressure points with the main center break throughs, & found a way out threw the breaking SW wall. The directional flow is materialized & solidified with the larger center blobs that popped up.
As someone born and raised in Los Alamos, I really love the detailed explanations here. I did have a question: is there an estimate of how high the volcanoes were prior to the caldera collapse? I had a science teacher there tell me that some thought the peak might have been higher than present-day Everest, but he couldn't really cite anyone's research into that.

Very thorough series on this topic, very well done! Great information! Thank you!
Thank you. . I've hiked that area and you have answered many of my questions 👍

Never mind...made it to the "myths" section of the last video, where this is dispelled. Thanks again!
Lol. "Not weapons grade material.".... Very appropriate given the proximity to the Los Alamos National Lab.
Is it known why the ring fracture volcanoes traveled in a counter-clockwise direction chronologically?
Righty tighty, lefty loosey
Ironic the obsidian is "not weapons grade", as 'ogive' is also a feature of military shells.
