At the exit to Lake Uist where in the immediate photo above you can see the shallow overflow over the man-made crib work - which seems to be an old dam barrier probably from sometime in the late 1800s or the early 1900s - we were amazed at the strange life forms shown in the first three photos. Our guess was brown algae co-operating to form funnel-like filters to concentrate nutrients in the water rushing by. In all three photos I am standing 'up-stream' and focusing on the funnel opening into the water current. As we walked with the canoe farther down the rocky stream we spotted many more colonies of these intriguing fragile brown algae clusters. By my estimate the 'funnels' were from six to twelve inches (60 to 120cm) long and perhaps one and one half to two inches across at the funnel opening (15 to 20cm).
If you know what these colonies are please leave a comment
