oil leak appeared overnight?

Thanks for the images, it helps. To tell what is leaking check the engine oil, power steering fluid, it does look like coolant, so I think you are safe there. We need to know which fluid it is; I would guess the oil pressure sender is leaking for the engine oil which is common here is the location of the sender so you can check it out. Also, I have included a guide that can help as well.

It could be the front engine oil seal as well; you might need to wash the engine off with degreaser and then start the engine for a short time and then recheck it. Check out the images (below). Please let us know what you find. We are interested to see what it is.

Thanks Ken. I will check the oil pressure sender, but I don't think that's it as the top and sides of the motor are clean and dry. It appears to be something on the bottom side of the engine, but it's so tight in there I can't see very well. All fluid levels are up right now. As a note, we do have an oil leak, had it for years, but never this bad (if that's what it is), and the power steering reservoir has run dry twice in the last couple of months.

Okay, it sounds like it will be the power steering pump or hoses. Here is how to do the pump replacement in the diagrams below. Here is a generic guide on how to change the hoses out so you can see what you are in for when doing the job:
