This camo green "ammo case" style cache can be found in the Churchill Rocket Research Range, located 23kms outside of town. The Churchill Rocket Research Range was used by Canada and the US in 1954 for research of the upper atmosphere using sub-orbital sounding rockets which gathered data. It was used heavily during 1957 and 1958 during the "International Geophysical Year", where countries shared scientific information between the east and west after the sharing of this information was disrupted during the Cold War. The Rocket Range closed briefly after 1958 before being reopened less than a year later by the US army in collarboration with the Canadian Government, where the US army stayed until 1970. After 1970, the Canadian National Research Council used the range until 1985 where it was largely deserted afterwards.
Currently the area and surrounding area is used by the Churchill Northern Studies Centre, a non profit research station that supports arctic and subartic research and education with the goal of sustaining the north. The Churchill Northern Studies Centre started in 1976, they provide accomodations, meals, equipment, lab space, rentals and logistic support for researchers who are looking to study the surrounding area. The Centre also supports education for the public by hosting learning programs for guests, where guests can learn about the northern lights, belugas or polar bears while getting the chance to learn about Churchill as a town and its history.
