I hope you don’t mind that I went ahead and looked at the other photos in that album. You’ve got quite a sausagefest going on. 
And that’s why that turtle ought to have thought about just what yard she was invading. I’ve heard turtle soup is delicious, and I’d be willing to give turtle sausages a try
I have a creek on my property, and female snappers will hike pretty far from a flood zone in order to lay eggs. They can be foul-tempered and extremely fast. See this YouTube video of a quick snapper: SUPER FAST TURTLE - YouTube
They prodded it! They’re not dangerous if you just leave them alone. They are notoriously cranky but honestly don’t care two whits about you if you just don’t bother them.
If you read all the responses, there’s several ideas…agitate with a stick, when it clamps on, pull it out of harm’s way. Or let it grab a stick, pull it onto a towel or something, then drag it on the towel (which is what I did a few weeks ago with a very large snapper in myn yard.) Smaller snappers can be picked up by the rear part of the shell and simply carried.
They are really quite non-confrontational and only get aggressive - understandably so - when threatened by a creature 10 times their size.
You reach down and you flip the turtle over on its back, Athena. The turtle lays on its back, its belly baking in the hot sun, beating its legs trying to turn itself over, but it can’t. Not without your help. But you’re not helping. Why is that, Athena?
What’s a turtle?
You’re late to the party.
Curses. Thought I’d read all the way through. I am ashamed.
That’s hilarious, it’s like, "Well. I. was. just . going. to. sit. here. a. while. but. I. see. you’re. getting. closer. so. I. guess. I. should. leavrerightnowgottagobye!
Ha ha ha you’re my new best friend, because I gave that turtle dialog, too.

My parents’ home is set next to a small park that has deer and other wildlife.
I wandered outside their house one summer because cops kept going up and down the driveway. When I stepped outside to ask, they casually informed me someone had reported the mama bear in our yard. Who’d managed to either 1) go up a quarter mile paved road and into the front of the driveway or 2) get around the 6’ tall fence.
I’m still pissed they didn’t scream at me when I waltzed out of the house nonchalantly to see what was up.
Well it WAS in the road and they’d nearly hit it. Obviously you leave it alone if it’s…elsewhere.
I was bitten by a snapping turtle when I was younger. It was a small one though. I despise turtles, so naturally my school’s mascot is a terrapin.
You’ve seen a tortoise, right? Same thing.
No worries 
Oh dear lord that was amazing, it’s the random linked stories that people pull out that make this the best message board in the known universe.
Found this link http://boards.straightdope.com/sdmb/showthread.php?s=&threadid=151130&highlight=fart reading that one, and nearly howled out in laughter from my desk.
Amazing stuff.
Oh, awesome turtle too.
Shut the fuck up! Now… Leonardo, he’s a spiritual brother, y’know, down with the shell and all that good shit. Then this cracker, Shredder, gets his hands on some metal claws and the boy decides he’s gonna run fuckin’ New York; gets a whole Foot Clan together. And they go and bust up Leonardo’s hood, the Sewer. Now what the fuck do you call that?
Don’t bother him, he’s in the middle of a big race!
Be glad they aren’t in your backyard. 
I don’t think anyone has posted soft-core Turtle porn. The ol boy is giving it to her good. Similar to the link above.
