Blast Furnace Slag

blast furnace slagblast furnace slagI picked up what I think is a piece of blast furnace slag from the beach at Sandsend last week. It looks a bit like a motorway chipping with the contrast of limestone fragments and black coating but the top surface is hard and pockmarked with bubbly holes, so this fragment has been subjected to intense heat.

There were ironstone workings at Sandsend.

Low Tide

Sandsend Ness, 2 p.m.
Sandsend Ness, 3 p.m.

cormorantLow tide is around midday, so we’re enjoying the two mile walk along the sand from Sandsend to Whitby. It was high time that we came to see the sea again. The waves heave and sigh; the surf swishes and fizzes.

Whitby harbour, 12.25 p.m., 59ºF, 15ºC, cool breeze from sea, hazy: A cormorant flies low over the water and out to sea via the harbour mouth.

crowA crow probes around the barnacle encrusted rocks on the west side of the harbour. Three or four redshanks fly up from the water’s edge, piping as they go.

turnstoneNearer the bridge, the herring gulls have the mud bank staked out. A turnstone does just that – turns over a stone – as we pass. In fact in the minute or so that we’re walking by it turns over four stones. When we humans are rock-pooling the advice is to carefully replace every stone we turn so as not to disrupt the habitat. The turnstone doesn’t bother with that.
