Forsythia_2024-04-01 SW Michigan USA

From a very large patch, near the North Country Trail in the Barry Game Area in SW Michigan. Walking these trails in state land we often see evidence of the hardscrabble existence of the farmers who tried to make a go of it in this hilly, sandy, rocky soil before they gave it up round the time of the dust bowl - the 1930s- and the state took the land. (large rock piles near the top of hills near a small, vaguely level area that was probably a farm field). Yet someone back then planted a few of these to brighten their day... and they spread.

Not sure of the species.
