What time for shade in the black corridor this time of year?

Hitting the black corridor in red rocks tomorrow.I know it gets a bit of sun mid day this time of year. What time in the afternoon  does it get shade this time of year?

There will always be routes in the shade throughout the day in the black corridor. You simply swap sides or go to the upper level from what I can remember.

This was 12:48pm last Sunday. Lots of sun but it didn’t last long.
