Update from the Lake: Tracks and Things...

...on the beach at Butt Valley Reservoir, also seen here and here.
Probably dog.
Sasquatch — I mean, human.
Small crawdad pinchers. Finger is red from blackberries.
Corbicula fluminea or Asian clam, not zebra mussel.
Jelly blob, probably Pectinatella magnifica, a type of freshwater bryozoan.
Enlargement of the same photo. This is a colony, and each of the circular to star-shaped indentations or rosettes supposedly consist of several individual organisms.
Shaly beach sand. Hopefully we'll see the reason for the odd shape of this sand in a few days!
