… or Unfurling Ferns.  Take your pick.  It drove me nuts trying to figure out what these were when I first saw them.  At this point I am guessing they might be Marsh Ferns (Thelypteris palustris) because… well because I found them near a marsh.

Location : Cowles Bog.  (Indiana Dunes National Park)

Date : April 25, 2021

Early spring ferns just beginning to unroll.

Looks like a nice fern family. Papa, Mama, and the kiddies.
