Ground tutorials?

Ground tutorials?

Greetings all!  I'm designing a side scrolling game and i will admit that this is my first game.  I'm using Game Maker studio and while I have the background designed, I'm at a loss on how to do the ground.  My idea is that my main character is going up a mountain so I won't have any platforms.  My question is this:  should I draw the ground in photoshop then tile the different pieces and build the rest in gamemaker?  Does anybody know where I can find good tutorials for this?  I've looked on Youtube and Google and found none befiting what I want to do.  Any help would be appreciated.  Thanks!
