  1. Boone L-1 Underground (Beeline distance: 48982 m) Boone L-1 Underground Boone is an underground power feed station for the L-1 cable leg from Lamar, CO to the Cheyenne Mountain Complex. It seems to have been built purely for this purpose, as the cable leg connecting CMC to the L-3I transcontinental is too long to be powered just from the ends. The station is still in use for the fiber route overlaid on the L-1 cable ROW.
  2. Transcontinental L-3I System (Beeline distance: 55659 m) Transcontinental L-3I System During the early 1960s, AT&T built a high-capacity transcontinental cable hardened against nuclear attack. The L-3I transcontinental cable served both to add reliable capacity to AT&T's commercial network, and to provide a hardened backbone for the rapidly growing AUTOVON military telephone system.
  3. Bonneville Power Administration Microwave Network (Beeline distance: 55659 m) Bonneville Power Administration Microwave Network The BPA's historic microwave communications network is well documented in a historical inventory, and was covered in Computers Are Bad. The first form of the network, built in the very late 1940s and early 1950s, used 23/24 channel ~2 GHz equipment from Federal Telecommunication Laboratories/ITT. During the 1960s many links were upgraded to 600-channel equipment (in 72-channel banks) over 8
  4. Colorado Overton Mystery Repeater (Beeline distance: 73297 m) Colorado Overton Mystery Repeater In Colorado, along the I-25 corridor south of Denver, there are several buildings that appear (based on various evidence, sometimes only circumstantial) to be telephone cable repeaters. It's hard to sort out their history, as several different long-distance lines have passed through this area over the years, including a transcontinental cable route that I know little about but might be related to this station. This is very much unfinished research and it's a di…
