Yeah - those are the chalky ridges (or rather remnants of bedrock formerly enclosed by limestone weathered away) of Helamakt's Shield and Sestarto's Leap.

Geology is more of a problem - limestone is a bad basis for lakes.

A very good rule. Still, you somehow seem to have a misconception of "bog iron" coming as iron, or even as useful ore. The stuff is a brownish crust just below water level on the flank of lakes and doesn't really require bogs, just some sort of loose soil above a layer of loam or rock which the runoff water doesn't penetrate, and sediments where chemistry changes once more under the ground water level. The "ore" comes out muddy, contains lots of unwanted impurities transported down by the rain as well.
The stuff is fairly ubiquitious, which rules it out as a source of iron for humans in Glorantha...
