Narrative:
On climbout at 3500 ft MSL we were issued a turn to besas intersection; the SID (PESKAL1) explicitly states no turn prior to 4200 ft MSL. Knowing that I did not turn and about 10 seconds later the controller from mdst control asked what our altitude was and we stated 3800 ft MSL and he told us not to turn toward besas until were we above 7000 ft. We complied. I feel that this was an oversight on the controllers part not knowing what altitude we were at when issuing a turn in mountainous terrain. Having good situational awareness was critical in avoiding a CFIT event. In summary maybe a call to mdst departure control to let them know that this should be avoided in the future; especially if IMC exists.
