Cannot take iron anvil in dwarf-fortress?

I'm quite new to dwarf fortress and trying to make my way thru it. I read most of the utterly newby guide and want to go. Now, I'm trying to make the preparations. In the item menu, it seems that i cannot take an Iron anvil with me. I know I have enough points but the anvil just won't appear in the menu. If i free 300 points, I can get a Steel Anvil tho. What's happening?

Finally, I surrendered. I just changed the embark location and it did the trick. I would think that because it was near a volcano and it had high cliffs, maybe my dwarves could not carry stuff as heavy as iron. (I could not bring iron bars either).

I wonder if it's because your parent civilization didn't have an iron resource next to it. I wonder if an item won't be provided to your wagon from your parent civ if they themselves don't have access to the resource. Where you able to select ANY iron items?
