Aircraft on training mission transiting from fortuna and arcata area to redding and red bluff area. Flew north of direct route to view crater lake. Descended over crater lake under VFR. Inadvertently descended lower than planned. Flew 1 slow pass over lake and departed to redding. Received call from park ranger, and major from military. Another pilot onboard resolved issue with military and the park ranger via phone conversation, jan 1997. Issue has gained the attention of squadron commanding and executive officers.
