Today was the second last day on site. Despite the start of the process of covering up the site in earnest, we nevertheless still carried out some exciting work.
In the broch, yesterday’s blogger; Jo, continued to take special micromorphology samples from the floors. Working in the ‘central passageway’, which is a kind of corridor space that permitted the occupants to access several rooms set against the southern side of the broch, Jo was able to take a sample and reveal a lovely floor deposit underlying the dark, organic occupation deposits. This is really good news because it means that almost all of the areas that we have investigated floors across the whole of the eastern and central areas of the broch we have this fairly standard process of floor-making in evidence. What happens is that nice clean clay floors are laid down, presumably as a kind of beaten earth floor and then these floors are lived and worked upon. This human activity then produces detritus and organics that come to look like thick black charcoal rich deposits. These contain wonderfully rich sources of info’ about how people used the broch.

Today when Jo was working in the floors she also found a piece of unburnt wood in one of the dark lenses of occupation. This is a very unusual find as, obviously, wood that hasn’t been charcoaled is prone to decay!

Elsewhere in the broch, in the western zone, work on the occupation deposits around the late hearth, produced lots of antler, including what appeared to be an antler tool, perhaps for tending the hearth, as well as lots of other animal bones, and what appears to be the edges of an earlier, probably more formal hearth underlying beginning to emerge.
We will be concentrating on the final cover up of the site tomorrow, so only a few things require to be completed and recorded now- but it has been a very good season, and I’ll be rounding that up in tomorrow’s blog. Tomorrow we’ll also tell you about all the fascinating geophysical survey that has been happening at the site while we’ve been digging.

But as a treat here’s an extra blog piece from Rik Hammond below. Rik’s an artist that has been working alongside us on site for several years.
