What to do with Baby Turtle at the doorstep!?

Help!

I just went outside and there’s a teeny-tiny turtle right in front of my front door. dscn1335I’m about a five minute walk from a nice-sized pond that has ducks and other waterfowl and lots of GIGANTIC turtles. But what is this baby turtle doing all the way up on my front step?

What should I do?

I temporarily put him in a bucket to keep him safe. But should I walk him down to the water’s edge and set him down there?

Does anyone know what kind of turtle he is? I tried to research on the Internet but couldn’t be sure.

Help me help this little fella out!dscn1336
