The Keweenaw Rocket Range was an isolated launch pad located in U.S. state of Michigan’s Keweenaw Peninsula. It was used between 1964 and 1971 for launching rockets for meteorological data collection. NASA, along with the University of Michigan, conducted the project under the lead of Dr. Harold Allen. The site was one of six similar sites scattered about North America used to collect measurements of electron density, positive ion composition and distribution, energetic electron precipitation, solar X-rays, and Lyman alpha flux.
Might have to check this out this summer.
