UFO Sighting in Snohomish, Washington on September 10th 1977 – I observed a sparkling light bouncing in a downward path disappearing behind a hill.

While out deer hunting and alone I observed this light bouncing in a downward path before it disappeared behind a hill. This incident occurred near Camel Mountain in Snohomish County. I've yet to undrestand what it was. I noticed this light--it looked like a sparkler(the firewoks type)--as I looked in the direction it appeared. Not knowing who or where to report this incident I just forgot about it.I thought it was a strange object and a UFO.
