The plaintext of K2 provides the coordinates
38 degrees, 57 minutes, 6.5 seconds North; 77 degrees, 8 minutes 44 seconds West.

Discussion as to where the coordinates point have provided a variety of possibilities.
One member, Xenon, has provided evidence that the coordinates point to a spot within the courtyard, specified, in the following image, by the red dot (surrounded by four smaller dots).

Xenon's explanation can be found here.

The linear aberations found in the face of the granite strata of the compass outcropping may provide further evidence that the coordinates provided by K2
may be pointing to the spot within the courtyard, specified earlier by Xenon.

Here's a reminder of the compass strata.

Here's a graphic of the compass rose, aberations in green; then rotated 180 degrees to match the aerial photos.

The compass graphic is now superimposed over the coordinate image, centered over the courtyard.

Here's another look.
