What I did Sun 1 May

Basically, went diving at Haigh quarry; logged 83 mins solo. First dive 53 mins to 25.5 metres, 5 C water (but with a drysuit heater, yay for Santi). Second dive 30 mins, 15metres 8C water (ditto!);

 

What you see at the bottom of a quarry is, basically, wet rocks (but usually in better focus)
But they're eerie - this is a view looking up a 10metre cliff, from about 20metres which is halfway up the cliff
there's an old cabin cruiser (with wall to wall carpeting, which is really useful at 15metres)
with a forlorn tricycle on deck
a very eerie interior
and the way out is a welcome sight
