Pile of stones
Fig. 17: A little above the second group of trees, at a depth of about 25 metres, you come across a pile of stones with tree trunks sticking out of it. What was sunk here once? Intentionally or by accident? Two Sea&Sea YS-110 strobes with glowdive diffuser domes. Dive 661: Dive site Pumpwerk Rüschlikon, Lake Zurich.
