Monday and it is back to work for the field school students. One major item on the agenda was to map in the grid points, excavation units and features with a total station. A total station is an optical instrument used to survey sites. Picture one is of a student with the total station, and one sitting on the ground recording the data. The second picture is of a student holding the reflector prism to which the person operating the total station aims at in order to record distances and angles of specific points on the site. This endeavour took the skills of three of the students most of the afternoon to complete. The end product will be a detailed map of the project area which can be used as a point of reference for future research at the Pickawillany.
