How does this visualization (including caption) advance ethnographic insight? What message | argument | sentiment | etc. does this visualization communicate or represent?

This visualization introduces me to the concept of shadow places—boundary zones whose histories of violence and extractive capitalism are obscured. The photo offers a striking juxtaposition to this concept. It is a visualization that is dependent on the larger photo essay for context and interrogates the interlaced meanings of masculinity, leisure and pollution in a post-industrial coastal site.
