Here's another female I found elsewhere (near where I had earlier seen a spottie slide into the water and slip out of reach beneath a submerged lip of tree roots. I groped after it for a few dozen seconds of 38-degree pain but came up empty handed), smoother shell indicating her seniority, and bearing the scars of a long-past encounter of something with teeth on her carapace...
Spotted turtles aren't the only thing swimming around the marsh wookin pa nub. I saw a couple red-spotted newts (Nopthalmus viridiscens) perusing the weedy shallows, walking/swimming forward a few body lengths and then weaving down among the matted dead grasses and leaves at the bottom before popping up again.
Here's a male, in the newt-equivalent of breeding plumage (really hard to portray this in the air - I need to bring along a transparent container to get a good shot). Check out the strongly keeled tail and, in the second photo the swollen vent (you can just see it behind the rear leg on the left).
I think I heard one or two wood frogs (Rana sylvatica) chuckling away, shouted down by the peepers. The woodies' work was apparent in deeper marsh pools - blobby egg masses soon to hatch out into tadpoles.
As tired as I get of the painted turtles (Chrysemys picta) it would be unrepresentative to leave them out of the trip account. I walked around a pond set in the marsh and heard dozens go skitter-splash as they got back to the safety of the water, though some stopped and tried to hide in the shallows where I could still get to them.
