Solved! It's the inherited memory of a nuclear explosion. From Kim Shumway:

"The drawing on his wall was a nuclear mushroom cloud. The idea was that even though he hadn’t seen the bombs that destroyed the world himself, the fear of them was kept alive among grounders and passed down through the generations. Thus their reaction to the bomb in “I Am Become Death.”"
