While departing from a dirt runway in mountainous terrain, the airplane hit trees at the departure end of the runway. The pilot stated that the airplane seemed to have good speed on the takeoff roll; however, by the time he was over the trees at the end of the runway, the stall warning buzzer was sounding.
