At the very tip of Michigan's remote Keweenaw Peninsula, is a site that was once instrumental in space exploration, the Keweenaw Rocket Range.

Today east of Copper Harbor about 5 miles past the end of US 41 down rutty seasonal roads, the site is not much more than a large concrete slab.  According to, who has visited the site,

The rocket range operated for just under a decade, between 1962 and 1971. Dozens of rockets were fired from the site during its lifetime, including two of the large Nike-Apache rockets noted earlier.  After those launches, however,  the site would never be used again. The structures were removed from and the land abandoned shortly after. In the forty years since, the site still remains just as remote and inhospitable as it did when the rockets were firing. Visiting the old rocket range requires a long and slow drive along a rather worn and washed out dirt road from the end of US41 for nearly a dozen miles to the peninsula’s tip.

There is a small monument erected by NASA to mark the site's historic importance. The plaque reads,

The state of Michigan established a rocket range on this site which was used from 1964-1971. Michigan's first rocket to enter space was launched from this site on Jan 29, 1971. In tribute to the historic work done in the field of rocketry, this memorial stone was placed in the summer of 2000 by GT FFRC NASA
