Easymodo dungeon finding:
Spoiler!

Notes:
- You can skip Step 1 if you're already acquainted with navigating your world (which I'd assume you are)
- I'd recommend digging a 2-wide or 2-long shaft straight down, alternating dig order. Just so you don't accidentally fall into any hazards that might be between you and the dungeon
If you don't have Paint.NET any image editor that can handle layers will do.

This is easier than Tesi's method (searching just for the spawners) since on cartograph spawners are just single squares. Searching for the Mossy Cobblestone (block value 48) reveals the whole room as much more noticeable rectangles.
