These are relief maps for the state of New Mexico. If you attended one of my workshops, you probably received a laminated version of one of these. Each file is the same thing – just at different resolutions.
I showed excerpts from this video in my workshops. This one video has two different things in it.
Spatter cones and fissure eruption up to the first 1:30 of the movie.
After about 1:30, the rest of the movie is of an AA flow. I showed this portion in the workshop. Although there is wind noise, you can hear the sound of the glassy boulders as roll down the front of the advancing lava front.
