Abstract
This paper proposes a practical first-pass method for identifying high-probability locations of undiscovered settlements, ceremonial centers, or gathering places from a given archaeological horizon: treat known sites as elevation anchors, then map the corresponding contour band across the surrounding landscape.
The Taş Tepeler region of southeastern Türkiye provides an ideal test case. Göbekli Tepe and Karahan Tepe, two of the most important early Pre-Pottery Neolithic monumental sites, are separated by roughly 46 kilometers yet share a similar cultural horizon and a comparable landscape logic. Both were placed on elevated limestone ridges above surrounding lowlands, close enough to productive plains, seasonal water sources, game corridors, and raw materials, but high enough to avoid the instability of wetter, lower terrain.
This pattern expresses the Living Edge principle: high enough to survive, low enough to thrive.
The method is simple, repeatable, and accessible. It requires only topographic maps, basic elevation data, or digital elevation model visualization. Where multiple known sites from the same horizon cluster along comparable elevation thresholds, other ridges, plateaus, saddles, and high-ground margins within the same contour band become prioritized targets for future survey.
This paper does not claim that every site at a given elevation will contain archaeology. It proposes a narrowing tool: a visual and testable way to convert known site placement into predictive survey logic.
The Taş Tepeler Example
Göbekli Tepe and Karahan Tepe are among the most significant known monumental sites of the early Pre-Pottery Neolithic. Although they are distinct sites with their own local settings, they share several important placement characteristics.
Both occupy elevated limestone landscapes. Both overlook lower terrain. Both sit within a regional environment where seasonal water, game movement, plant resources, raw materials, and visibility would have mattered deeply to early communities. Their placement does not appear arbitrary. It reflects repeated selection of the productive threshold: the boundary zone where environmental safety and environmental opportunity meet.
In Living Edge terms, this is the phase boundary between exposure and abundance. Too low, and the settlement or gathering place risks marsh, flood, seasonal instability, or disease pressure. Too high, and it loses efficient access to water, animals, plants, and daily movement corridors. The optimal zone is the edge: elevated enough for permanence, close enough for life.
Göbekli Tepe and Karahan Tepe therefore function as elevation anchors. Their present-day elevations, surrounding topography, and landscape positions can be used to ask a simple question:
Where else in the same region do similar elevation thresholds occur?
That question does not prove the presence of undiscovered sites. But it does produce a rational search field.
The Predictive Method
The proposed method is intentionally simple.
Identify known sites from a specific archaeological horizon.
Record their present-day elevations and immediate topographic settings.
Establish a working contour band around those elevations, allowing for local terrain variation.
On a regional topographic map or digital elevation model, shade the corresponding elevation band.
Identify ridges, plateaus, saddles, high-ground margins, and threshold zones that fall within or near that band.
Cross-reference those targets with known archaeological gaps, areas lacking systematic survey, local reports, oral traditions, older site inventories, and satellite-visible anomalies.
When possible, overlay hydrological data, paleoenvironmental reconstructions, soil transitions, slope analysis, and modern color-gradient imagery from tools such as Google Earth.
Where these different visualization styles converge, confidence increases. A ridge at the target elevation band is interesting. A ridge at the target elevation band overlooking a former wetland, watercourse, game corridor, or resource zone is more interesting. A ridge with surface anomalies, local tradition, or survey gaps becomes more important still.
Where the data diverge, the discrepancy is also useful. It may indicate later erosion, sedimentation, tectonic movement, human modification, or incomplete paleoenvironmental reconstruction. In that sense, the method is not only a site-prediction tool. It is also a landscape-questioning tool.
Elevation Is Not the Claim
A central limitation must be stated clearly: elevation alone is not the explanation.
Human communities do not build solely because a hill has the correct altitude. They build because a location solves many problems at once. Elevation is only one visible proxy for a deeper settlement logic involving water, safety, food access, visibility, movement, stone, ritual meaning, and social organization.
The value of elevation is that it is measurable. It gives researchers a starting grid. It allows known sites to be converted into regional search parameters.
The method therefore should not be read as:
“Same elevation means same archaeology.”
The stronger and more careful claim is:
“Known sites from the same horizon may reveal preferred elevation thresholds, and those thresholds can help prioritize future survey.”
This distinction matters. The method is not deterministic. It is probabilistic. It reduces the search area without pretending to replace fieldwork.
Why This Matters for the Living Edge Framework
The Living Edge framework proposes that human organization repeatedly emerges along phase boundaries: coastlines, river margins, upland-lowland transitions, forest-grassland edges, oasis margins, marsh borders, ridge systems, and other zones where risk and abundance meet.
Civilization does not arise from abundance alone. It arises where abundance becomes organized.
The Taş Tepeler sites offer one of the clearest early expressions of this principle. These early builders selected elevated but connected terrain. They were not isolated on mountaintops, nor were they buried in unstable lowlands. They occupied the threshold.
By treating known sites as elevation anchors, researchers can convert visible landscape patterns into predictive tools. The method is especially useful in regions where waterlines, wetlands, river systems, or productive lowlands shifted dramatically over time.
This contour-shading technique could be applied beyond Taş Tepeler, including regions such as:
the Great Lakes basin;
ancient river-margin settlement zones;
upland margins around former wetlands;
desert-edge oasis systems;
the Grand Canyon region;
Amazonian disturbance zones;
post-glacial shorelines and lake margins;
other landscapes where hydrology and habitation shifted together.
In each case, the question is not merely “Where was the water?” The better question is:
Where was the Living Edge?
A Practical Survey Protocol
The Taş Tepeler test case suggests a simple field protocol.
First, establish the anchor sites and their elevation range. For Göbekli Tepe and Karahan Tepe, a preliminary working band should begin broadly around the regional high-ground threshold represented by both sites, rather than treating the elevations as exact matches.
Second, map every comparable ridge, plateau, saddle, and high-ground margin within the selected study radius. The goal is not to produce a final answer but to produce a ranked target list.
Third, classify each target by strength of convergence.
Tier 1 targets would include sites in the elevation band with strong ridge placement, overlooking productive terrain, near plausible water access, and containing visible surface anomalies or prior local reports.
Tier 2 targets would include sites in the elevation band with good landscape position but weaker visible evidence.
Tier 3 targets would include elevation matches without strong supporting landscape features.
This creates a disciplined way to move from broad observation to testable survey design.
Future Work Required
Several next steps are required before the method can be evaluated rigorously in the Taş Tepeler region.
High-resolution digital elevation models should be built for the Şanlıurfa and Tektek Mountains region. Known sites should be plotted against slope, aspect, hydrology, visibility, and distance-to-resource layers. The working elevation band should be refined rather than assumed. Paleoenvironmental data should be used to estimate wetter lowlands, former drainage patterns, and seasonal resource zones.
The method should also be tested against known site inventories. If known sites repeatedly cluster within certain threshold zones, the method gains strength. If they do not, the hypothesis must be revised.
Finally, predicted targets should be cross-checked through satellite imagery, LiDAR where available, ground survey, surface collection, geophysics, and excavation only where appropriate and legally authorized.
Conclusion
The Taş Tepeler sites suggest that early monumental builders were not choosing locations randomly. They appear to have understood the value of the productive threshold: high enough to remain secure, low enough to remain connected to abundance.
This paper proposes a simple way to read that threshold on the modern landscape. Known sites become anchors. Elevation bands become search fields. Ridges, plateaus, saddles, and high-ground margins become ranked survey targets. The method is not proof. It is a disciplined first filter.
The Living Edge principle does not replace archaeology. It helps point archaeology toward the places where life, safety, movement, and meaning were most likely to converge.
If Göbekli Tepe and Karahan Tepe mark one portion of that ancient threshold, then other portions of the same landscape may still be waiting to be recognized. By reading elevation contours as predictive Living-Edge maps, researchers may better understand where the first monumental communities gathered, built, and survived.
