A bright and very early Sunrise in Spokane Valley in Washington, State.

May I pleasel request, Earthsky to help me understand a bit easy as to how the on Western coast sun was up about an hour earlier than it must have been up on Eastern coast, taken into account the 3 hrs daylight time difference here, and also understanding the elevation is different.
But am having a blank moment in making a clear picture of the reasoning learned in younger life 🤔
