I spent the summer of 1980 at Indian Mountain AFS Top Camp working on a contract with Bureau of Land Management to provide radar weather observations of thunderstorms. At the time I was an enlisted weather observer in the ANG and did my weekend "training" at the bottom camp weather station giving relief to the personnel there on those days. I retired in 1996 after 23 years many as a weather officer at NORAD (including crew duty in the mountain) and US Space Force (AF Space Command then). That included several trips to Thule. Assessing Missile Warning and AC&W radar site performance degradations due to space and terrestrial weather phenomena was a primary responsibility and constantly briefed to the Command Post as well as mission centers (my office was collocated with the Missile Warning and Space Surveillance teams in the Mountain). After retirement I worked (and still do) for Raytheon. One my jobs was South Pole (yes Antarctica) communications engineer for 8 years which took me to the Pole. On looking through the library on day I came across the book 90 South by Paul Siple about the construction of South Pole station and the first winter over. Inside the cover was a stamp: Property 708th AC&W SQ Library, Indian Mountain AFS. How serendipitous. Somehow after the installation closed the book made it through a disposition system that took it from the AF to National Science Foundation to the South Pole. And I saw it. Amazing.
