This is a base map showing the layout of a federal facility or military installation. The map identifies key locations including Route 12 along the northern boundary, I-95 access to the northeast, Main Gate #1 at the southern entrance, and a Security Building (Bldg 500) near the main gate. The facility includes numerous numbered buildings and structures (ranging from the 300s to 500s) distributed across the property, bleachers, parking areas, and internal roadways. The Nautilus Memorial is noted at the southern waterfront boundary, and a primary parade ground is labeled in the central area. The map provides directional orientation with compass indicators and shows the general spatial relationship between facility structures and external transportation access points.
