Strange things always happened around the Clausland mountains, and my College lay on the ridge.

One of the strangest things on the mountain was the former Camp Bluefields. During World War 1 it was used as a rifle range and a POW camp. Miles of underground tunnels litter the top of Clausland Mountain, dark and mysterious. Many call it ‘Tweed’ because it lies off the winding Tweed Boulevard.
The tunnels would provide safe passage from one rifle range to another
with only small slits every few yard to provide illumination. The
fascility was abandoned after WW1 because many times stray bullets
would hit homes in the local towns and even started fires.

Some
of the tunnels are over a mile in length and even in the broad daylight
you cannot see the other end. Rooms that were used as barracks, prisons
and offices are located near almost every tunnel. In
some of the larger rooms there is evidence of Satanic activity as
pentagrams and odd hieroglyphs litter the aged cement walls. Fire pits
are often found with pieces of bone and clothing. It is whispered that
these are the remains of some of the ritualistic killings.

The
tunnels are frightening to enter in the daytime but go in them at night
is an intensely frightening experience. You can feel a disturbing
presence throughout the area. It is as if something is watching you.

There are 4 entries about these tunnels and the terror that they inspire the intrepid explorer in the book  "Weird New York" by Chris Gethard. The articles confirm
the evil presence that most feel when they enter the dank darkness of
the underground system. On page 20 of the book under the title “Not Just Evil, but also Dangerous” contributor Mark Miljko writes:

“The reason why the police don’t like to go in ‘there’ is because there was and still is a practicing satanic cult who use the Clausland Mountains
for their satanic rituals. There have been many bodies found up there,
most of whom have died in a sacrificial manner. The cult members are
referred to as the Omega Men. Their names are the only ones scribbled
down the farther tunnels and all around the opening of the first with
threats and the like.
