[I still remember a talk that @RelaenaSindelar gave about pharmaceuticals in the waste stream; one of her examples was Sequim, WA - in the banana belt - with retirement communities' flushed medications’ and the downstream/coastal effects - NOT the Grand Canyon! :( ]

The image displays a stunning view of the Grand Canyon's South Rim, characterized by layered rock formations in various shades of red and brown. A solitary pine tree stands out prominently on the left side of the frame, its branches extending upwards with green needles against the clear blue sky. The terrain is rugged and barren, with sparse vegetation consisting mostly of desert shrubs typical to this arid region. The photograph captures a vast expanse of geological formations that illustrate millions of years' worth of sedimentary processes at work. There's an absence of human presence or artificial structures in sight, emphasizing the natural grandeur and untouched beauty of this national park landmark.
