Late-afternoon side light finally made the rock textures readable. A 1/3 stop of underexposure kept the sky from clipping; everything else came back in post.
Sampling every 30 seconds was overkill. Five-minute intervals gave the same discharge curve and stretched the logger runtime from nine days to almost six weeks.
