Geology

Our friend Richard the geologist has not been able to visit yet. But the new British Geological Survey website is full of information. Go to http://www.bgs.ac.uk/opengeoscience/digMap50viewer/ and then navigate eastwards from Loch Hourn for the Wood. If you use sufficient magnification Loch Quoich and Loch Poulary are labelled. The bedrock is Upper Garry Psammite Formation and the superficial layer is mostly hummocky (moundy) glacial deposits - diamicton, sand and gravel. Our own superficial peat bogs are also marked.

Psammite is sandstone. (The psammead is a sand fairy.) Who told us we were on granite?

Perhaps we should be excavating our horticultural grit onsite, just as we got our road-making material there.

photographs of assorted glass and chinawear now available on Picasa; they are currently stored on top shelves in Droitwich pending relocation to Birmingham, Oxford, Nottingham or points North

also the best of the 3 washed out pictures I took last weekend, will be sent to Canada next weekend unless a better option appears (I've not been taking many photos recently)

This is a funny place to be doing this; but, oh, granny's milk jug with the wide lip. And are any of the stem glasses the pretty, old ones? (Probably not.)

I MUST down and then up load my pictures of Diana in Canada.

I found the geological maps a but hard to decipher on Safari. But also how do they KNOW?! Has someone other than your good selves been marching round the wood drilling out samples? Or can you tell from the vegetation?

Cecilia said...

When Richard comes we will ask. The whole map is full of interest, don't you think?

Janet said...

You don't know what's there unless you drill everywhere. They just interpolate between boreholes.

We used this website to get information for Rebekah's GCSE Geography coursework, but the site has been modified since then.
