The Explorations. Continued.
Entered the tunnels via the grate near the Boiler House, and continued to the point where the tunnels branch off to the left toward Floyd and Dalton. Went straight and ended up in the boiler room of Heth. Took a tunnel on the opposite side of the boiler room and passed under a circular grate, shortly ending up in the boiler room of Pocahontas. Another tunnel led from the opposite side of the room, turned left under a grate, and came to an intersection where the tunnel continued straight and to the left. Went straight and ended up in the boiler room of Bolling. A tunnel continued from the other end of the room, but it required crawling. Backtracked to the most recent intersection.
Took the new direction underneath Moffett Quad, and had to choose left or right under a grate. Turned left and then right and got to Draper. Flashlight was dying, so exited at Draper.
Entered the tunnels via the grate near the Boiler House, and continued past Heth and Pocahontas to the intersection under the grate at Moffett Quad. Turned right and found a tunnel leading off to the left that ended in the boiler room of Ingles. Turned around and went left and confirmed that the tunnel connected to the one leading to Washington, after passing under a rectangular grate and climbing over a concrete obstruction.
Turned around and headed straight back to the tunnel where it turns right to go to Draper. Headed straight and ended up in the boiler room under the West Wing of Moffett. Went through a door to the left and down a corridor to another boiler room, under the East Wing of Moffett. Exited through Moffett.
