		<description>David Gilbertson writes - When we carried out the original study of morphological variation in the common dogwhelk Nucella lapillus in the early 80s, we went to great lengths to establish that the changes that were being observed in the ancient Mesolithic coastal shell middens were NOT due to changes in coastal configuration compared to the preent day. The ancient (~5000) year old coastal geography of the inner Hebridean island of Oronsay (the west coast of Scotland - find Oban and go south west; and then immediately south of the island of Colonsay: there are a number of Scottish islands named Oronsay) was reconstructed from geomorphological evidence. This coastal reconstruction served to re-inforce the conclusion that the overall mesolithic shoreline was less stormy than today. (see also Paul Mellars (1987)Prehistoric Human Ecology on a Small Island. Edinburgh University Press). The initial investigation was fortunate in the shape and situation of the island of Oronsay; and in the other information available about it (search under Oronsay Fieller, Gilbertson, Olbricht, Jardine). As the commentator above suggests - in this type of study it is vital to establish the coastal geomorphology of the time from independent evidence other than that of the dogwhelk shape, and for this to be used as part of the evidence base used to reconstruct the palaeo-oceanography.  It could be that other molluscan taxa might also be sensitive to details of the wave climate - e.g. netted dogwhelks.  The subject of palaeostorminess at the coast might also be addressed more directly by investigating the remains of crabs if they occur in number in coastal middens.</description>

		<description>Brian - nothing wrong with fine grain resolution, but like you said you also need the big picture.  I like to open a big hole and then bulk sample everything from some units (i.e do the fine scale analysis in a few areas of the dig).  Its also good to have a reason for the fine scale analysis - and you have done some awesome stuff in this area (activity areas in houses).  Collecting everything and doing really fine scale analysis just because you are expected to do so, is a waste of time and resources.

I also like the typo in your comment -  for 'wet' you put 'wept'.  I often feel our community volunteers are weeping when we force them to dig in the rain.  I am not a big believer in covering digs with tarps - the light for digging is terrible, photographs are ugly, and the wind always blows the things apart anyway.  One year it rained so hard we had to bale the housepit every couple of hours.  We used the water to wet screen!

		<description>Hey Patrick - I also was breaking my students in for digging on Kodiak when we worked through the rains in early October. I've seen enough of your field photographs to know that a little bit of rain never kept your crews from their excavations. My students didn't really seem to mind getting wept. I kept telling them we're doing this for science. They can take an English literature class if they want to stay comfortable.

Great analogy about digging and pixels. As you know, I'm one of those "high resolution" archaeologists. I may not zoom down to the micromorphology level, but I do like analyzing the little stuff. You're absolutely right, though, that we need the big picture or the details have no meaning. 

We need a big dig at the church site just so we can deal with our unstable walls. I think we could relatively easily open up a large block - maybe even use a backhoe to remove the fill. I'd really like to have another chance to see what's left inside the church.</description>

		<description>Brian - it looks like you are breaking the students in for digging in the arctic.  Only in the arctic there is no warm lab.  Some snow and a little rain, fog and you'd be there.  Frozen ground that you have to wait on to thaw would be a nice touch.  Maybe you should open up a big hole in late March?

Must say I like big holes myself.  I always equate a dig to a digital picture.  You only have so many pixels - all you can do is change the resolution and size of the picture.  Fine scale, high resolution and you can only look at part of the picture (say the tip of a nose on a face).  Low res and you can examine the whole face, but it looks like an impressionist painting.  But at least with the low res you can see that you got a face.  Too often archaeologists  dig so fine they have 
no idea what they got.  Dig big and you see the houses!

Finally - it is pretty cool that the basement is still undisturbed.  I'd say that is a HUGE discovery.

		<description>Well I'm glad to hear you were saved by Caleb. He's been a hero to us all.</description>

		<description>Completely untrue.  Well, at least the part about going back to Hancock!  Luckily Caleb pointed out I was definitely not part of the sixth grade class before their teacher did anything drastic.  Close call, let me tell you...</description>

		<description>You definitely took some pictures that I would not have taken myself. I particularly like the shot of our first artifact bag - 001. I wondered if you took it intentionally to document the start of the dig - or was it just an interesting shot?</description>
