The Carcadia Burn zone is one of the largest areas in the game, and it is packed with dozens of ECHO Logs scattered across multiple sub-regions. Some can be grabbed right away when you first arrive, while others are tied to specific side missions like Her Own Funeral or The Power Ballad of Rodd Vomit.
