Ramat Rahel Region Analysis

Decent Essays

Terraces have long been considered to be one of the agricultural marvels of the human past. Existing since the time of the Old World, terracing has increased the surface area of viable farmland while helping to reduce soil erosion and limit water loss (Davidovich et al. 2012:192). Recently, scientists have been aiming to discover more about past human settlements through the excavation and dating of terraces using complex soil dating techniques. One such excavation project is located in the Ramat Rahel region of Israel, where scientists have been attempting to set a time period for the terraces that define the agricultural landscape of the area. In order to accurately and efficiently put a date on these pastoral marvels, archaeologists use …show more content…

Location itself played a significant role. The Holocene stream terraces are located along the San Pedro River on a major floodplain. The flooding of the San Pedro and its two main tributaries combined with the local precipitation levels causes the terraces to inevitably experience “local erosion of bars and infilling of swales” (Onken et al. 2014:22). The dry climate of the Ramat Rahel region allows for the terraces to remain, for the most part, out of contact with water that might erode the rock and sediment and destroy possible archaeological finds. Differences in the main type of dating used also led to differences in degree of accuracy. In Ramat Rahel, the primary test used was OSL dating. The consistency of the results from all the land samples along with the formation of logical age clusters upon further comparison “testif[ies] to the direct relationship between the placement of the terrace fill, wherever it is sourced, and the bleaching of the quartz within the sediments” (Davidovich et al. 2012:203-204). The accuracy of the OSL results gave scientists fairly certain date approximations, especially when compared to the results of the Holocene terrace dating. In the Holocene, radiometric dating was used as the primary method; it provided broader dates and time ranges than did the OSL
