Could I get some more advice, please ?? smile

Before I go further into the Maxos Temple or venture into the poisonous first room of the Temple of Doom eek I'm trying to gain experience points by finishing up other quests - one being the finding of the four parchments.
I have three of them and I think the fourth is somewhere across the river from the Tribal Shrine, in a really high up spot ??
But I can't find a way to get there.
I've crossed the river via that log a dozen times at least now and searched every which way but never found a route that will take me up to the right place on the tops.

If finishing this quest is worth the hassle wink could anyone please point out a successful route ??

Thanks biggrin
