High-water marks

More than three months of overflowing rivers around the Twin Cities finally ended this month, leaving debris, tree trunks stained by muddy water up to above my height, and a sprout and seedling explosion around the Minnesota Valley National Wildlife Refuge in Bloomington. I took a walk there yesterday to see if the mushrooms and slime molds were more active yet. The answer was yes. This system of wetlands goes hand in hand with flooding, even months of it, so life carries on.

I’m not kidding about the seedlings. Maples a few inches tall and other young plants were as thick as turf grass on much of the Minnesota River floodplain after millions or billions of seeds carried by the flooding settled down and germinated. They’re a record of the flood as much as the lines on the trees: Thicker bands and patches of sprouts echoed the water’s direction and speed. Down in the marshier area, creeping plants regrew to their former size.

To cap off the hike, one last peek in a little ravine near the trail revealed the biggest crown-tipped coral fungus I’ve yet seen. Almost always, somehow, there’s some kind of prize at the end.

Happy summer, and thanks for looking.
