RE: PARACHUTE FOUND NEAR THE KALAMA RIVER ROAD
On September 7, 1972, SA [REDACTED] advised telephonically that he had discovered a parachute hanging from the top of a tall pine tree, approximately 15 miles from the end of the Kalama River Road. Thirty yards from the tree in which the parachute was found was a piece of white plastic on which was inscribed the following: "United States Depart- ment of Commerce, NOAA - National Weather Service, Radio Sonde."

[REDACTED] stated the parachute was a reddish color with white shroud lines. The parachute appeared to be slightly smaller than a normal-sized parachute and appeared to have something hanging from the end of it that looked like part of a box.

On September 7, 1972, [REDACTED], United States Department of Commerce, National Weather Service, 909 First Street, Seattle, Washington, advised his department uses parachutes to recover radio sonde equipment attached to weather balloons. [REDACTED] explained that a balloon is released with the radio equipment attached to it. The balloon rises to a preset height, at which time the balloon explodes. The radio equipment then falls a short distance and a small parachute opens and carries the radio equipment safely to the ground. This parachute is slightly smaller than a regular-sized parachute and it is pink in color with white shroud lines. [REDACTED] further stated that housing the radio sonde equipment is a white plastic box with the following inscription: "United States Department of Commerce, NOAA - National Weather Service, Radio Sonde."
