Alas, once again you’ve caught SA staring at the newsfeed (now in four languages). Those high-school French classes sure come in handy!
Every once in a while an archaeological project comes along that sets new standards for spatial and temporal integrity. This project is staggering in its scope.

In the extreme north of France work progresses on a portion of the canal Seine-Nord de l’Europe, an immense excavation project is enabling what must be the largest 3-dimensional archaeological survey in human history. The scale can only be fathomed pictorially, and INRAP (l’Institut National de Recherches Archéologiques Préventives) has kindly provided us with an up-to-the-minute birds-eye view of the undertaking, complete with rare glimpses of Late-Middle and Early Upper Palaeolithic archaeology that are truly boggling—extensive archaeological sites on the order of 1,000 to 4,000 sq. m. These are not encampments, but places where paleo-people left their mark, just the same. From yesterday to the Mousterian and everything in between. Flint artifacts and well-preserved animal bone are the predominant traces, and while numerous, the artifact scatters are by no means dense. Yet, they tell a story that would not otherwise have been told: what life was like for Neanderthals and modern humans in periglacial Europe.

Here, in Havrincourt (Les Bosquets, HAVRINCOURT, Pas-de-Calais, Nord-Pas-de-Calais, France), heavy machinery is exposing more than 7 m-deep löess deposits in vast, stepped, trenches, illuminating life in the millennia before the last glacial maximum. Löess is extremely fine, wind-blown dust that blankets many parts of Europe, Asia and North America in deep, mostly unstratified deposits. Even if this kind of sedimentation were not indicative of the climate during which it was laid down, evidence of large-scale permafrost features (visible in the photo below) would tell us the same story. These excavations of the Mammoth steppes of northern Europe are truly phenomenal in their scale.

Years ago, Leroi-Gourhan excavated at Pincevent, an open-air site in the Paris Basin, where overbank deposits had gently buried an immense Upper Palaeolithic camp site about 13 kyr ago. Not to denigrate the fabulous discoveries at Pincevent, but these present-day exposures in northern France beggar that evidence in the sheer enormity of the artifact scatters, and for the time-depth involved—30 to 50 kyr.

To watch a video recounting these excavations is to get an impression of what most cultural resources managers, and indeed, most palaeoanthropologists can only dream of—the ability not only to study the archaeological landscape in two dimensions in the present, but to have the ability to follow it back in time as well. While you’re watching the video, note the technical expertise of the shovel operator—deftly scraping away centimeters at a time to enable archaeologists easily to spot the artifacts.

I’d keep an eye on these investigations. We’re sure to learn a great deal about Neanderthal behaviour and how it compares to that of modern humans under more or less the same environmental conditions.
