HM-69 Sentry Dog Kennels

Natural Attraction
A small white building with adjacent squared in fence. Flat landscape is covered with grasses.

At HM-69, you'll see the remains of a Cold War-era security structure—a small concrete building and enclosure that housed the Nike base's sentry dogs. Each base maintained about four specially trained dogs, each bonded to a single military police handler, tasked with patrolling the inner and outer fence lines every night without fail. The dogs were trained to attack anyone except their handler, and soldiers would take shelter if one escaped its leash. This small, preserved structure embodies the intense perimeter security of the nuclear age.
