Calibration Mark AG49 with Satellites
2016
archival pigment print
55 x 44 inches
A few of the calibration markers like this one are made primarily of rock rather than concrete. The artists hypothesize that it is because they were constructed at higher elevations and the weight of the materials, including water at 8 pounds per gallon, would be too labor intensive to transport. Only markers at higher elevations were built from rock. The artists like the way the rock references earlier civilizations' rock formations which were also meant to be seen from the sky. |
