 In 2013 Tepper and the Jezreel Valley Regional Project dug test trenches measuring approximately 295 feet by 16.5 feet that revealed clear evidence of the camp.Aerial photography, satellite images, and high-resolution lidar data hinted that the hill known as el-Manach contained traces of artificial, human produced objects and structures.After this, slight depressions in the earth revealed the borders of the military camp itself.
