Narrative:

On climb out I made a right turn to fly up the canyon southeast of ogden towards heber city. I normally contact hill tower for a transition through their delta surface area for this flight. I attempted to contact hill tower; but they were not open. As I was distracted figuring this out; I received a terrain alert from the aircraft as I was approaching rising terrain. I pulled up and made a sharp right turn to resolve this; in so doing I crossed into slc's bravo airspace briefly without clearance. The main cause was my erroneous assumption that hill tower is a 24/7 operation as many military towers I have previously dealt with in the area. A contributing factor is the tight arrangement of the airspace in and around ogden/hill area that does not allow VFR to pass between the mountains and the airspace without clearance.
