Near sundown last Thursday, it turned cloudy. I’d parked on a two-track, in an area of marshy ponds, amid acres of reeds, to watch the arrival of loud vees of Canada geese — and a smattering of sandhills and great blue herons — landing, honking and creaking, jostling, and claiming their campsites for the night. Suddenly the sun dropped into a thin zone of clear sky at the edge of the horizon, and everything around me blazed up in a marsh fire of illumination! Here are a few views of that sunset in the slough. Note: the delicate grass in the foreground (taller than my head) is a prairie native known as Big Blue-Stem.
