Skeletons: sea-sorted

Gently, the waves carry and deposit their offerings, seeking suitable places to pile them: fine black grains of coal in the hollows between ripples; grey-white tangles of hornwrack, heaped beside a log, the minute animals dead within their skeletal cells; … Continue reading

“Look!”

“Look what I’ve found!”“Look at that!”“What’s this?” We do it automatically, hold out the treasure on our hand. For about 10 years I’ve been taking pictures of what people have found when they joined me for low-tide guided walks on … Continue reading

The balance sheet between blue and green

‘A thin blue line’. Of policemen edging a protest march? The blue halo of Earth’s fragile atmosphere as seen from space? No – in this case, a blue line that Robert Alcock painted along a sea-wall in Bilbao in 2011, … Continue reading

Dune walk (with one diversion)

Boring molluscs and bevelled edges

What’s an AONB?
