On Wednesday we completed excavation for the 2012 season. The AlDf-30 site proved to be far more complex than we had anticipated. In addition to two superimposed dwellings floors, we encountered an enigmatic depression in the subsoil which incorporated a robust boulder and cobble feature. To our knowledge, there are few analogous structures in the known archaeological literature from the Maritime Peninsula – a fascinating puzzle to end our fieldwork at Port Joli!
We have formulated several hypotheses about what it could be, but it would be premature to make any firm determination before further analysis. We will analyze all of the data we’ve collected in the lab, including a careful study of the artifact patterning within the feature, before making an interpretation about its function. In the meantime, we have found it very useful to visualize the structure in 3D to understand its overall shape and the internal arrangement and orientation of the rock feature. Below, I’ve uploaded a video of the 3D model we have created. Similar to previous posts, this 3D model was compiled using 123D Catch, and was created from over 60 high resolution digital photographs of the feature.
