Devil's Den, Boulder-strewn hill in Gettysburg, United States.
Devil's Den is a rocky hill in Gettysburg covered with large diabase boulders and blocks scattered across Houcks Ridge, creating natural trenches and raised positions. The rock formations create a maze-like terrain with narrow passages and open spaces between the stones.
During the Battle of Gettysburg in July 1863, Confederate forces captured this rocky position from Union troops in fierce combat. The struggle for control of the rocks resulted in over 2,600 combined casualties across both armies.
The name comes from local folklore about a large snake called "The Devil" that supposedly lived among the rocks before the Civil War. This story shaped how people thought about the place long before it became a battle site.
The site is reachable from Crawford Avenue and Sickles Avenue with many interpretive markers to guide you through the terrain. The paths between the rocks can be uneven and slippery, especially after rain.
The rock layers formed during the Triassic Period roughly 180 million years ago through ancient volcanic and sedimentary processes. This geological history predates the battle by countless ages and shaped the terrain that soldiers would later fight over.
