Liv and I retrieved one dive flag, the rescue divers recovered the other, and we went home feeling good about a long and successful day of diving. ![]() By late afternoon we had guided all the students through their first low-visibility dives without incident. When divers’ fins fluttered too close to the soft bottom, we signaled for them to adjust their trim and buoyancy to avoid silt plumes. We took students underwater in groups of two, waiting for their anxious breathing to subside before swimming with them along the transect. We marked the corners of our site with dive flags, laid out transects for divers to follow and hoped that the threatened autumnal rains would hold off for one more day.
