How old is the Devil's Den?
How old is the Devil's Den? The warm spring water mixed with the winter air caused the steam to rise, thus the name “Devil's Den” was given and it has stuck ever since. With a maximum depth of 54 feet, Devil's Den Spring offers ancient rock formations that date back 33 million years.
What is an interesting fact about Devils Den?
Devil's Den was formed with Little Round Top (to the east) and Big Round Top (southeast) by periglacial frost wedging of the igneous landform formed 200 million years ago when a diabase sill intruded through the Triassic Gettysburg plain. The feature acquired its foreboding name prior to the 1863 battle.
