AH! So same kids from the garden gnome project I posted earlier. For some reason everything I’ve been doing this year takes place outside? Figured it would be good to get back into drawing interior spaces!
Inside an underground nuclear explosion created cavity, 1961.
Lawrence Livermore National Laboratory’s Project Gnome, the first nuclear Plowshare experiment, was designed to explore the feasibility of using a deeply buried explosion in a dry salt bed for energy recovery and scientific nuclear experiments. The 3.1-kiloton device was detonated at a depth of 360 meters near Carlsbad, New Mexico. A researcher explores the created cavity, 23 meters high with a diameter of 49 meters.
