Geology MOOCs?

Are there geology MOOCs anywhere? Every time I go looking I find at most like three but one's in Chinese (which I don't know nearly well enough to take a course in), one's some advanced thing, and the other... I don't even remember.

Anyway, is there anywhere I could possibly peek into a course like... Rocks an' Whatnot 101 maybe? Dirt Stuff for People with Clean Hands, maybe? :'D I can't promise I won't end up disinterested or get bored or distracted and quit, but I want such courses to be a thing anyway.
