Clarence was a well known stream denizen, but one day he was n't there. The counselor staff at Creek Forest did n't fret at first. Clarence would sit in the stream on a log at his spot, taking in the sun's rays, but he would also disappear for hours at a time. Swimming around, hunting for worms and other morsels, meeting lady turtles, or whatever it was that turtles did. The staff all liked Clarence. He was a male slider, and his regularity made him a popular subject of stream lessons. Clarence would sit amused as kids on the stream bank would stare and go `` ooh'' in amazement at his size. 
 
 But when his disappearance continued into the second day, people started to worry. None more than Clarence's biggest fan. She studied herpetology in school, and knew that Clarence faced no natural predators here. Wolves had long been driven out. Foxes and coyotes maybe, if there were any, but they were too small to break Clarence's hard shell. Snakes would eat turtle eggs, but not Clarence. Other counselors thought he might be on an extended trip somewhere, but she suspected differently. Why would he leave his favorite spot, on the log above the stream pool, where food and sun were plentiful? 
 
 Plus, the other turtles seemed uneasy now. They would slide into the water with a splash before she could get close to them. Any noise, like the croak of a raven would be followed by a cascade of turtle splashes. 
 
 All through the day, she thought about Clarence when she could. What could cause him to leave, what could possibly attack him? She stared off into the distance, towards the setting sun. Birds were flying, sillouhetted against its falling fire. Flying into the sky, and then back down to the same spot. 
 
 Something was n't right. She got up and ran out to the distant field, hoping it was n't Clarence out there. But she stopped in shock. Sure enough, the ravens cawed and flew away upon her arrival, but the carcass they were picking at was unmistakable. Clarence lay on his back, carapace broken open, turtle no more. 
 
 Soon other counselors would arrive, and gaze horrified, or with cool acceptance of nature's brutality. Ravens never attack turtles, they said. Their shells are too thick. Especially when they're withdrawn into them. And what was he possibly doing in that field all alone? 
 
 People looked at the ravens in a new light after that. They were new arrivals to that park - the handful that lived here arrived only a few years back. How they had gotten Clarence was never fully appreciated. 
 
 Until the next time they found a dead turtle out there, same spot as Clarence, meeting the same grizzly end, did they realize how the ravens did it. Clarence was too tough for the ravens to peck at. But he was not too heavy for them to carry.
