Larch ball
The larch ball is a structure created when Western Larch needles floating in a lake become entangled in a spherical shape due to the action of waves. They are most commonly known to form in Seeley Lake, Montana, however, they have also been known to form in similar regions such as Clark Fork. Typical specimines are 3 to 4 inches (8 to 10 cm) in diameter more rarely larger ones are found.[1]
