IN WINSLOW, A BUILDING BOOM WITH NO CLEAR EXPLANATION.

---

The facility, which sits on approximately forty acres of land purchased by the federal government through a series of transactions that were not publicly disclosed until local reporters obtained the records through a Freedom of Information Act request, consists of at least six large buildings, several of which have no windows.

---

A seventh structure, partially underground, is visible only from the air.

---

The General Services Administration described the project in procurement documents as a "research and logistics facility" and listed the client agency only as "DOD-Other."

---

Route 137, which passes the facility's main entrance, has been subject to intermittent closures that the sheriff's office has attributed to "utility work," though residents say the closures often coincide with the arrival of flatbed trucks carrying equipment under tarps and unmarked white vans arriving in convoys of three or four.
