File talk:Frost hexagons.jpg

Hi, I'm just doubting that this picture is from a blockfield. It looks like dried ground. Blockfields are made up of exposed bedrock that has succombed to frost shattering. This picture doesn't seem to do justice to that...

The picture at this address is in my opinion more appropriate: http://www.fettes.com/Caithness/images/scarabenviewa.jpg

Just a thought.
