Narrative:

On approach runway 20R to sna on a visual from the west runway 20R. The captain was flying and was cleared visual approach. As we descended over the mountains; I asked him to stop his descent because I felt we were getting to close to the terrain. Just then; ATC also asked if we had the terrain in sight because we were well below the minimum vectoring altitude. The captain had lost situational awareness and responded to me reporting that we were well above the pdi (pilot direction indicator). I realized at that moment that he was not aware of our proximity to the ground. He felt bad; but I felt worse because I had let it get to a point that I was not comfortable. I was well aware of his experience and did not want to offend him. I could hear in the voice of the ATC person that she too was not comfortable to have to question a professional.
