I can’t say this it’s universally true for all swamps/marshes, but I have found that springtime at the Horicon Marsh is especially welcoming and photogenic. Not only are bug levels low, but the vegetation is cropped closer than in mid-summer and the new-growth reeds create interesting lines and patterns.
The patterns and reflections from these silhouettes look like a cross between some sound oscillation scope and Asian character sets. More open water reflects evening colors for more drama.
