After acknowledging instructions to maintain VFR, the pilot informed the controller that he was descending to his destination. The helicopter impacted mountainous terrain at the 4,600 foot (msl) elevation level. Weather at the nearest reporting point, 8 miles south of the accident site, included a 2,900 foot msl broken cloud layer and a 4,900 foot msl overcast cloud layer.
