I need some real help with Martin's Idol.. there are some spoilers in this..

I've been up the mine path and found both the T'rang warrior you can recruit and the Indiana Jones mine cart ride, but both mine rides lead nowhere. One path dumps me out by the T'rang warrior, and the other looked to be a new area, but ended up a little above the shack where I grabbed the cart in the first place. This freaken Idol is really starting to get on my nerves.

Can someone shed some light for me..

anyone?

Spoiler:

Take a look around the room with the mine carts. There are some
switches which determine route the mine cart takes.
