Can this be mud?

Although visitors to the Bay of Fundy are quite intent upon seeing the tide in at its full vertical height of 40ish feet, I am constantly intrigued by our shoreline at low tide - when our 100 billion tonnes of seawater is out bulging in the Atlantic ocean somewhere. It's at low tide that Fundy turns awesome if only you have the time and inclination to discover it.

This morning I took an early morning walk along the centuries old Acadian dykes at low tide from Port Williams to Wolfville, Nova Scotia. On one side of me, salt marsh and mud; on the other side, lush farmland. Not ideal weather for photography - the light was diffused by random clouds and early morning shadows - but Fundy surprised me again and the pictures took themselves. My photos of mud are usually ooey, gooey chocolatey but not this morning - today they were soft planks of pewter.
