Silent Sentinels
2021 - 2025
Along the invisible line that divides North and South Dakota lies a string of quartzite monuments, obelisks engraved with symbols and glyphs seemingly indecipherable except to those who placed them in this vast landscape. These markers serve to separate land that was, not long ago, united under a singular name that is now divided in two. A former wilderness that still bears the name of indigenous inhabitants from whom the land was stripped, bifurcated, and sold off parcel by parcel.
This line of stone monuments to politics, separation, and territoriality is documented and explored in the body of work titled Silent Sentinels, a series of photogrammetric models and 3-D printed sculptures. Removed from the context of the landscape that they divide, these reproduced markers become impotent reminders of the power that these borderlines have socially, politically, and economically not only between the two states named “Dakota,” but all the borderlines within and outside of the United States.
Each sculpture in the Silent Sentinels began as a three-dimensional photogrammetric scan of the original obelisk. The scanned data was then processed to create a 3D digital object that could be rendered for printing using fused deposition modeling methods - the most common method for 3D printing. This method allows for the extrusion of molten plastic in .04mm layers to build up the final model.
The example to the right consists of the 3D model created from photogrammetric scan data and the resultant 3D FDM print. Specifically, this monument is the initial mile marker placed on the eastern-most point of the North Dakota and South Dakota border where it intersects the western edge of the state of Minnesota on the western shore of the Bois de Sioux River near White Rock, South Dakota.

Special thanks to the South Dakota Arts Council and the Puffin Foundation for their support of Silent Sentinels through grant awards and financial backing. Without their help, this project would not have been possible!
