We got onto the water early each day, pushing off from the pier in Bridge Bay at 6 am. The pain of waking up early, however, was mediated by the incredible views of the sun rising over the mountains as we motored out onto the lake. The visual tableau was different every day, reflecting the different moods of the lake through the interplay of light dancing on water. Behold our office! Photos by Rob Sohn, WHOI.
