Since the introduction of Google Earth, I have been fascinated by the study of prehistoric landscapes from an aerial perspective. What began as curiosity gradually developed into a systematic way of observing sites and their surroundings. Over time, I expanded this approach beyond satellite imagery alone and began working with elevation data such as the AHN (Actueel Hoogtebestand Nederland). By switching between different layers, subtle patterns and deviations become visible that are difficult or impossible to recognize at ground level.<\/p>\n
This way of looking led me progressively further back in time. While studying early prehistoric sites, I encountered publications about Tjerk Vermaning. Rather than focusing on the debate surrounding his finds, I wanted to understand the locations themselves. By examining these known sites in detail, recurring irregularities emerged\u2014patterns that did not easily fit purely natural explanations.<\/p>\n
<\/p>\n
<\/p>\n
It became clear to me that Paleo-period traces cannot be understood by studying a single site in isolation. Pattern recognition requires comparison. To learn how such traces manifest in the landscape, many sites must be examined side by side. Over the past years, I have done this intensively, first in the Netherlands and later in other regions.<\/p>\n
When I shared these observations with professionals, I was often told that people from such early periods did not leave recognizable traces in the landscape, or that any traces would have been erased by meltwater, erosion, or later geological processes. What I observed was generally attributed to natural Ice Age formations.<\/p>\n
During these exchanges, someone working at the Netherlands Cultural Heritage Agency told me that identifying discolorations or irregularities at already known sites amounted to \u201cwishful thinking.\u201d Yet it is precisely the repeated study of well-documented sites that allows patterns to be learned and recognized. Known locations provide essential reference points. Without them, there is no baseline against which new observations can be meaningfully assessed.<\/p>\n
<\/p>\n
<\/p>\n
A key issue is scale. Paleo sites are often treated as small, localized find spots. However, when examined at landscape scale, many appear to consist of clusters of activity areas rather than a single location. This may explain why some areas are interpreted as workshops with dense flake scatters, while nearby zones are described as butchery sites. These are likely different functional components of one larger activity landscape.<\/p>\n
In this context, what is identified as a \u201ccamp\u201d is rarely an isolated unit. It is more often a fragment of a much wider terrain used repeatedly or over extended periods.<\/p>\n
<\/p>\n
<\/p>\n
In the Netherlands, Paleo sites are almost never open-air sites. One can stand on a known location and see *******\u2014no structures, no surface finds. This absence is often taken as proof that ******* remains. Yet many traces only become visible through elevation models and relief analysis.<\/p>\n
Absence of evidence is not evidence of absence.<\/p>\n
Some archaeological reports implicitly acknowledge this broader scale by referring to large areas with dense artifact concentrations, suggesting long-term or repeated use rather than brief, localized activity.<\/p>\n
<\/p>\n
<\/p>\n
Preservation is strongly influenced by the nature of the substrate. Boulder clay is dense, cohesive, and resistant to reworking. Unlike sandy soils, it does not easily erase disturbances. Once modified, it tends to retain edges, boundaries, and structural irregularities for very long periods of time.<\/p>\n
Meltwater and erosion may affect surface layers, but they do not automatically remove deeper or well-defined features. In some cases, disturbances even become more pronounced as surrounding material erodes more evenly.<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
To test whether these observations were region-specific, I expanded my research beyond the Netherlands. In South Africa, where many Paleo sites are open-air sites, similar patterns are visible in calcrete and limestone layers. Large artifact scatters often extend across extensive areas, clearly demonstrating the true spatial scale of Paleo activity.<\/p>\n
Closer to home, comparable conditions occur in Limburg, where limestone and loam form stable, workable substrates. Here too, I have observed irregular patterns that differ from surrounding natural formations. These materials, like boulder clay and calcrete, appear particularly suitable for preserving long-term traces of human activity.<\/p>\n
<\/p>\n
<\/p>\n
Across regions and substrates, the same principle emerges. Stable geological layers\u2014boulder clay, calcrete, limestone, loam\u2014can function as long-term archives. When Paleo sites are examined comparatively and at landscape scale, recurring patterns appear that are easily dismissed when viewed in isolation, but difficult to ignore when they repeat across multiple locations.<\/p>\n
<\/p>\n
<\/p>\n
What continues to motivate me is that at every site I study, traces become visible once I know how to look. I remain deeply fascinated by the clarity and coherence of the patterns that emerge\u2014patterns that reflect deliberate use of the landscape by people whose knowledge and capabilities should not be underestimated.<\/p>\n
For this reason, I repeatedly return to the same sites. As new satellite imagery becomes available, I re-examine known locations to see whether additional traces reveal themselves under different conditions. Over the years, I have built up a large archive of images, allowing comparison through time. This ongoing process is not about forcing interpretations, but about learning\u2014slowly and carefully\u2014how prehistoric landscapes can be read.<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
