Yes, also likely of the Genus Bidens. That small island, while very weedy, is a nice place for field botanist like me. I love sorting out the identification of plants which other people call 'weeds'. I do see halberd-leaved tearthumb there though, which can take over and act like the boss of a place.I took these on Lake Lenape on Sept 28, 2024. It’s one of the small islands that are found on the very northern part of the lake as you enter the creek. It looks like the same yellow flower I photographed at Menantico Sand Ponds this fall?
