While out doing telemetry, one of the squirrelologists decided to dig around at the entrance hole to a tree cavity. This tree is in the central, perhaps busiest parts of campus. He found half of a blue mussel shell. Although this picture is not the best, close inspection shows no real evidence of having been cooked. Perhaps a squirrel foraging on the beach carried it over? A gull certainly could have carrier it over too. The closest sandy beach is 0.31 miles away. Hmmmm delicous.
