I lived in Phoenix AZ for about 3.5 years, took lots of family to visit the Grand Canyon many, many times. So I have a good feel for how it looks in different weather and different times of the year.
Here is a live webcam from Kolb Studio at 8.12am local:
And here is my best effort with Free Cam, about 20 minutes later:
Well done Asobo it’s a great start. Good detail, sun shadow is accurate in the foreground and it feels like being there.
Colours are not quite perfect. However they change a lot in real life so its tough to get correct.
Notice in the far distance shadows in real life, but slightly over bright in the sim. The North Rim is 10 miles away so its a tricky rendering task as my 1080TI might not be loading the best textures.
Apart from the technical nit-picking, I think it looks beautiful in the sim and the view brings back happy memories.
The Asobo artist that did the sun rendering deserves a big thank you.
