The 4000ft site is typically about the inversion layer, which keeps it warmer than the valleys in the evenings through mornings. This is because the valleys will radiate, or lose heat at night, but the atmosphere, as a whole does not. That you mentioned through.

As for daytimes, I haven't observed it being warmer...but it is above treeline, so there is more solar gain, and less transpiration, so I guess it could be warmer?!?!

The reason why it's warmer than the summit is a bit more obvious.

Hope this helps,.
