Reported freezing rain and/or wet snow falling as the helicopter flew past their ranches at low alt heading nw. It was completely dark at the time of the acdt and the area where the acdt occurred is sparsley populated providing few ground lights for visual ref. The helicopter crashed in hilly, snow covered terrain in a near vertical, nose low attitude and was destroyed.
