stuck in Rift

[Sheila]

I got to sunrise, out of the caves/tunnels, out into the open, and can't go any further. When I try to go back Bokden says "That's a bad idea. Let's cross the rift" (or to that effect). I've tried up and down, right and left, and am stuck. What happened?

I found secret rooms 6, 13, 11 and 14 in this part. Did I miss something I needed?

Never mind. I just tried back and forth, and found a tunnel!
