During a preflight wx briefing, the plt was advised that VFR flight was not recommended due to low ceilings and reduced visibility. Subsequently the acft collided with trees on a mtn ridge at an elevation of about 1800 ft. a park ranger stated that all ridges in the vicinity of the accident site were obscured at the approximate time of the accident. Wreckage examination failed to indicate a system malfunction or failure. Several propeller slash marks were found on tree branches along the wreckage path.
