The Undersea Ledge

Objectives
Find Marshal Valentine's shipwreck on the undersea ledge nearby.
 * Find the shipwreck on the ledge

Description
So, now that we can hear each other again, lemme tell you what's been goin' on up here.

Apparently we were off by like, a league. Somethin' about undersea currents, somethin' about the tides of time, yadda yadda. I think Zelling is getting rusty.

Point is, you're not far off now. We're SURE that Marshal Valentine is right to the east of ya, in a shipwreck up on a ledge. Zelling says there's something else big up there too, but he can't tell what it is.
