ahhh, where do I start. Being an archaeologist I have a very close affinity with all things dirt/mud, especially this time of year with all the rain. Everyday, I find myself in some strange place trying to tease out our past from our friend 'the mud'. At present I am working up on the Royal Mile in Edinburgh excavating the remains of the old Toll Booth or prision. There is not much to see really except the robbed out remains of a wall that has been destroyed by past/modern services. I sit there examining the mud, rolling it, smoothing it, squishing it in order to decide if that bit of mud is the same as the other bit of mud I have uncovered i.e different contexts or layers of time. Archaeologists usually define the different types of soil using a book called a munsel chart. This is filled with little glossy pictures of colour (rather like a paint sampling book) that can identify each type of soil. This is then used along with texture etc to decide which type it is i.e Oxford clay. The soil is both my friend, enemy and livelihood, without it we would all be in trouble. I find the stuff fascinating and every field I pass I cannot help but poke around at the ground and wonder if there is anything down there. I have always said there is archaeology in every field, it just depends on what you are looking for??
