Analysis

While en route, the acft collided with moutainous terrain (trrn) at an aprx elev of 13,500 ft. previously, the plt had requested & was rcvg traffic advisories fm ARTCC. Bfr the acdnt, the acft's psn & alt (mode c reply) were noted by the controller (ctlr). No trrn/obstn alert was issued; however, at that time, the flt was operating under visual flight rules. Also, it was near a route often used by VFR acft to cross over the mtns, so no safety alert was required (altho after the acdnt, oakland ARTCC began providing trrn/obstn alerts to VFR acft as an adnl service). The acft crashed into 32 deg upsloping trrn below mt keith (elev 13,976 ft), aprx 8 mi nnw of mt whitney. On the latest sectional chart, there was a note (aprx 1/2 inch fm the crash location) which stated 'caution - rapidly rising terrain.' Also, the chart had 2 max elev figures which showed that nearby trrn rose above 14,000 ft.
