In the 1975 image, the initial clearing for the San Julian settlements is visible along the highway—the pink line heading north-south. Later images show a well-defined 3x3 box pattern with roads connecting them. The United States Agency for International Development (USAID) helped fund new roads along with wells and community center clearing.
In the middle of the two groupings of nucleos is a clearing of a different pattern. This is the Zapito private farm, which is not part of the San Julian colonies.
