25th February

Solo. At the cave about 1½ hours

Weather forecast (Met. Office) is for heavy rain spreading in this afternoon, dry in the morning. So decided to head over to HR and level yesterday’s spoil dump before the rain came and turned it to slop. While I was there added just a few rocks to the extension wall because I couldn’t resist doing so.

 As I headed back over Mendip (south>north) the sky had darkened and it was just beginning to rain!

Ferromanganese spherules in small fragments of crust (sample 006/COW). Now need to consider which formed first; the spherules or the crust?
