you can also see a small muddy stream to the left(on the left of what was the main spillway towards the bottom) in the second shot .
it was raining and cloudy all day
Exactly... why would the small muddy stream be clear in the one pic? That makes no sense.. it is eating through a saturated hillside, why is it not muddy in both images? That was what initially pointed me in the direction of exposure (blown highlights). While cloudy, lots of light still gets through, and in variable amounts with cloud cover... our eyes are not that sensitive to changes in light, believe it or not, but digital I,aging devices with more limited dynamic range can be quite finicky in shadows and highlights, leading to some pretty nasty artifacts. I’m hoping that is all these images show, but only about 70% confident.
