I am in the Lava Canyon, I make it to the far
side of the canyon, nut I can't make it to the top. I move the blocks but I am unable to climb to the top of the middle ramp. HELP

If you are where I think you are (based on your description), there are three blocks that can be moved--two of the blocks are on the bottom level, and the third block is located up one level beside a ladder. You must move the first two blocks back far enough that you can walk UNDER the what you referred to as the "middle block." Then you must climb up to the third block (beside the ladder) and then climb over it so that you can push it to the end of the ledge. Climb up onto the block and jump onto the "middle block." Let me know if this makes sense or if it helped--it was hard to describe. Good luck!
