[Answered] Tanzan Mountain Strength Puzzle

[TKGriffiths]

I've heard about it but....where is it?!

I found a steel beam that leads to a Rock Climb wall in the area next to the meteor base where Giant Steelix came from, that seems to be a dead end. Is it down there somewhere? It is possible I missed an area down there it all looks very similar.

The area on the right with all the ledges just before route 1 is inaccessible, it looks like I can make my way east there but there's an unmovable rock in the way.

Maybe I need to progress further in the story? I've just been told to go to 7th street if that helps.

There is a green rock blocking the path. It is located in the cave where you met up with Saphira before you went into Route 1. You need to do the 7th Street events and I think defeat the Dark Gym Leader. You will get a "Crystal Plug".

I did suspect it was progress related, I just like to complete all areas as much as I can before I progress the story. Was afraid I missed this area so I wanted to check. Thanks!
