Excavation techniques

Excavating techniquesAt our site, Kao To Chong, we are excavating two trenches, A and B. Today my group and I excavated trench B. An exciting discovery was made by one of my team mates while excavating which was important not only as a find, but as an example of proper excavation techniques. As I had the pleasure to observe, my team member while using his trowel, a tool used to remove soil from subsequent layers, discovered four to five long bones in a relatively good condition throughout his excavation unit. First, this was an important find because the good condition of the long bones may help provide very useful information about this site. Second, this find allowed my colleague to excavate in a special manner in order to leave the bones in situ until the surrounding dirt has been removed. The reason this is important is because by simply pulling out the bones once they are first discovered, relevant contextual information may be lost. They may be part of a larger bone assemblage which the excavator simply can not see yet as an example. By using his trowel, he was able to excavate down around each bone until he reached the bottom of his excavation unit. Providing the ability to see how the bones are assembled in situ and allowing for proper recording and handing to take place. His style of excavating was very important, and one which I also plan to use if I were to run into any sort of significant find at our site. This is just one of the many examples of the excellent work being done by the team here at Kao To Chong.
