The prehistoric village acquired drinking water through a rainwater harvesting system, consisting of carved channels [22] that fed several cisterns carved into the bedrock under the site, [23] which could hold at least 150 cubic metres (5,300 cu ft) of water.
Rio Huitzilapan debris flows est. 600–870 Debris flows destroyed village of Barranca Grande, and were 40 to 65 m (131 to 213 ft) deep. Debris flows extended >40 km (25 mi). Triggered by M~6.5 earthquake. [69] 1921 Almaty, Kazakhstan: Alma-Ata Debris Flows ~500 A debris flow in the Valley of Alma-Atinka River destroyed the town of Alma-Ata. [69]
Blanks are the starting point of a lithic reduction process, and during prehistoric times were often transported or traded for later refinement at another location. Blanks might be stones or cobbles, just as natural processes have left them, or might be quarried pieces, or flakes that are debitage from making another piece. Whatever their ...
Most LS is generated on highlands by erosional processes related to mass-wasting, sheet flow, rills and gullies. The deposited colluvium has a low travel distance and accumulates in midslope drapes near the site of erosion, in aprons or sediment wedges at the base of the slope or in fans at the mouth of gullies, debris flows and tributaries.

Thousands of rocks that bear a strong resemblance to prehistoric tools have been found at the site, both on the surface, and up to 8 m (26 ft) below the surface. A stone from the Master Pit had been dated to over 200,000 BP. This date could have been the result of contamination from other elements in the soil, so currently there is an effort to ...
Tell Barri, northeastern Syria, from the west; this is 32 meters (105 feet) high, and its base covers 37 hectares (91 acres) Tel Be'er Sheva, Beersheva, Israel. In archaeology, a tell (from Arabic: تَلّ, tall, 'mound' or 'small hill') [1] is an artificial topographical feature, a mound [a] consisting of the accumulated and stratified debris of a succession of consecutive settlements at the ...
These "purple zones" show areas where landslides, known in geology as "debris flows," are likely to start. The zones make up 13.3% of the mountainous counties in western North Carolina, which adds ...
He then compared the counts and weights of experimental samples with debris from two prehistoric workshop sites in western North Dakota. The result shows the experimental data sets can explain the technological composition of archaeological samples. Samples from several other sites also are applied this method and derive clear discriminant results.
