 SCP-648 is a hidden entrance of the Red Hedge Maze, near Data Expunged. When subjects enter the maze via SCP-648, they are displaced to what appears to be an extra-dimensional space. So far, several anomalous properties have been observed. The maze behind SCP-648 blocks all radio transmissions, preventing communication or remote recordings of the inside of the maze. The maze behind SCP-648 has a size inconsistent with the Red Hedge Maze. Manned exploration attempts have explored over 14 square kilometers of maze, without reaching any exit or edge to the maze.
