how do you get passed the waterfall in the earth level

This is a big problem and I've tried everything to get over the huge waterfall. Hiro just won't jump high enough to reach the boulder jutting out half way up the waterfall. I tried going back but it's blocked I can't believe no one has an answer on this problem all I see are the same cheats but no info on the way past earth level 1. you're not the only one with this problem no one seems to care about this. I wish there was some kind of solution- the only thing I can think of is to use the level cheat and skip that part of the game-but that just makes me feel like I didn't complete the game right so I'm really reluctant to do it that way I'm still waiting for a solution
-Thanks if you can help.

I hope this ends the frustration of the waterfall obsticle

You all probably found the way out of the waterfall dilemma
however, if you are still stuck and cant get over the waterfall on the earth level I will give you the solution. There is actually a path to the left of the large pond with the boulders in it. It's easy to miss because the camera want's to heard you in the direction of the waterfall but go against the camera and you can't miss it. I felt rather stupid trying many hours to jump over the waterfall just to find out that it's not possible and the path out is so close. There is one cool thing I discovered though. While exploring the lower left area of the map -there's a secret
passage that leads to an anvil. after picking up the anvil a life appears and you can grab that as well. good luck on the rest of the game.
