From around May or June last year I believe. You can zoom in or out on sections of this photo by clicking on it or using the smaller photo on the left. There are a couple more photos of the Canchete area at the top right you can click on as well or use the arrows.
The roads appear to be well traveled by big equipment that I have looked at in some other photos. There appears to be a picture of what may be a Dynacor truck crossing the Acari River on its way to Dynacor,loaded?
IMO
