From the publishers blurb: From the author of Bone Hoard of the Dancing Horror, The Imperishable Sorceress, and The Revelation of Mulmo! Welcome to the Dungeon of Crows, a megadungeon for Labyrinth Lord and other Old School Role-Playing Games! I have included ascending as well as descending AC to make conversion easier. I have also includes saves in the same Fort, Reflex, Will format that 3.x used for easier conversion. Within you will find what remains of the Skullheap Goblins, a few vermin known and surprising, a mysterious rhizomatic growth, and the blue and red goop PCs will surely interact with. This product contains the first 28 encounter areas, as well as a map for the western half of Level 1. (The eastern half requires navigating the underground lake, or coming up from below.)
