Narrative:
Written off (destroyed) September 12, 1975 when crashed into trees at Poudre Canyon, near Twin Lakes, Adams County, Colorado (at approximate Coordinates: 39°49′30″N 105°0′16″W): aircraft circled trying to out-climb rising terrain, and flew into a blind canyon. Both crew killed. According to the following excerpt from the official NTSB report into the accident:

"TYPE OF ACCIDENT: COLLIDED WITH TREES
PHASE OF OPERATION IN FLIGHT: OTHER
PROBABLE CAUSE(S)
PILOT IN COMMAND - IMPROPER IN-FLIGHT DECISIONS OR PLANNING
MISCELLANEOUS ACTS,CONDITIONS - FLEW INTO BLIND CANYON
FACTOR(S)

NOTE: Although the NTSB report gives departure airport (and arrival airport) as "UNKNOWN/NOT RECORDED", the location of the crash is about 25 miles north-north-west of Denver International Airport. It is therefore logical to presume that the aircraft was either travelling from (or to) this airport
