Pollen on Sebago Lake
October 19, 2007
This picture showing pollen on the waves of Sebago Lake in Maine was taken in the early afternoon of June 16, 2006. It's an example of how a periodic and nonlinear activity or motion can create odd but beautiful patterns. The pollen had been collected by the wind against a retaining wall. Dry, windy weather following a prodigious release of tree or grass pollen allow these minute particles to be readily seen, on cars, for example, but occasionally even on water surfaces.
