Hollow Way ?

Looks like a track for feet only, doesn't it?

Downs- Dry Valley

An abrupt break of slope- shows how, even in the winter, the chalk is a really "dry" land- very porous rock, very thin soil above it. "Dry Valleys" are thought to have formed
in glacial and periglacial times when the rock would ahve been frozen, so water flowed on the surface. (NB, much of the Chalk lands in Britain are south of the last major ice sheet, so you cannot really see any particularly glacial features.) Anyway, the trees seem to like it in the bottom there, even if they don't grow on the top.

Soil Types Chilterns to Vale

Again, Spencer can explain...

Nothing New Under The Sun

I'll let Spencer explain this one! ;-)

Close-up pf the Ridge and Furrow


A close-up of that Ridge and Furrow

Downs- Ivinghoe Beacon

This pic shows a sharp change in land use with the break of slope.

Spencer's photo's #1

Spencer took this photo on Ivinghoe Beacon in Buckinghamshire. In the middleground is a field with what looks like the remains of an ancient Ridge&Furrow field pattern. The foreground field lines are modern, I am sure. Click on the photo for a bigger pic. That Windmill looks abit odd, stuck there in the middle of the field...

There's agood map of this picture at:http://www.multimap.com/map/browse.cgi?client=print&X=495000.044346869&Y=217000.116830443&gride=494853.044346869&gridn=216648.116830443&scale=25000&coordsys=gb&addr1=&addr2=&addr3=&pc=&place=&width=600&height=500&db=freegaz&keepicon=true
