- The Bandelier Tuff - At this stop we are on top of the Pajarito Plateau near the Los Alamos airport. The canyons carved into the Pajarito Plateau are a good measure of how much erosion has occurred in the past 1.25 million years. The Lower Bandelier Tuff, erupted ~1.6 million years ago from the Toledo Caldera, makes up the valley floors and vegetated slopes. The Upper Bandelier Tuff, erupted from the Valles Caldera at ~1.25 million years ago, makes up the pinkish-orange and beige cliff exposures. There is a thin package of sediments and tephra deposits in between the two tuffs, termed the Cerro Toledo Formation.

I used to live in Los Alamos in 1990 and explored many paces there. And I have flown into and out of the airport in in a Mooney. It’s challenging at times. Thanks you for these videos, it’s hard to explain to my wife but your videos showed her what I’m talking about 👍
Amazing series
Fascinating, awesome…
Excellent series of volcanic presentations and most informative. I have subscribed to the channel. Looking forward to learning more about the area.
Great discussion of the temperature of the pyroclastic flow's affect on the deposit's solid/soil-like composition.
Woohoo, I'm your 1000th subscriber! Thank you for the video series, I just spent three days in the Jemez Mountains and wish had seen this beforehand.
Geology is the most entertaining of the sciences...use of google earth-flight helps a lot👏
Valles is one caldera I never really learned about in detail...great...
My buddy and I ducked into a cave on the southern side of Horse Mesa during a monsoonal thuderstorm and watched a huge waterfall blast off the side of the airport on the opposite side of the canyon. Erosive--you bet!
When I would dig in my yard in Los Alamos as a small child I would come across the reddish layer of tuff not far beneath the topsoil. My first first thoughts were that the layer was made up of the remains of dead devils that had been buried in Hell's ceiling,
