I love the patterns of the water that you captured from your vantage point. Love the dark waters where the force of the Skagit meets the depth of the Ross reservoir.
The other intriguing element is the exposed land. I know that there are hundreds of thousands of tree stumps on the dry lake bed, yet from this elevation they are invisible.
Also surprising is the persistence of the roads that were cut into the lake bed, to aid with the log transport. Several decades later, these are still visible - and at elevation as well!
Finally, it would be interesting to include your altitude in the EXIF notes. Not sure how you could do this automatically, but it would offer one more wanted data point with the generous info that you already provide.
