Wow, sun in January from 11:30 until 4:00 clipped at 3:00. Magical!
Out to mile 20 which I have posted;;; precisely corrected to GMT and repositioned to Rivermaps; I'm feeling with all humility aside: pretty precise.
I have Google Earth Street-View/ground truthed EVERY camp out to mile 20. By this I mean Google Earth has the entire Grand Canyon street viewed from a mid river perspective. CHECK IT OUT if you have not already.
With minor mental adjustment to Rivermap coordinate perspective, horizons are spot on.
I have total faith now in solar paths validated by SunPath.
This is something you can plan by if it matters I think. I look forward to further ground truthing.
