Notes:  About 50 miles south of Pittsburgh in the first range of the Allegheny mountains, George A. Lehew reportedly found a cavern which he penetrated for over a mile, the passages becoming increasingly wider. He descended at about a 45-degree angle until reaching a room in which he found a 6-ft.-wide thermal bore, a perfectly circular shaft with smooth glazed walls that had apparently been melted through the rock/earth in some ancient time. Old-timers in the area alleged that six “survivors” in 1915 took gear and equipment and spent a month exploring the cave, going 18 miles from the entrance and down almost 5 miles below sea level, where they distinctly heard the “rumble of machinery” off in the distance.

Location: Blue Ridge Summit Pennsylvania
Functions: Unknown

Tunnels to: Unknown
Notes:  The location of the so-called “underground Pentagon” maintained by nearby Ft. Ritchie, and used as a major electronic nerve center for the U.S. military. A massive installation that is also known as “Raven Rock” or “Site R” that was blasted out of greenstone granite 650 feet below.

A 260,000 sq. ft. facility sprawling beneath 716 acres composed of five different “buildings” in specially excavated separate caverns, literally forming an underground “pentagon“. Also contains fluorescent lights, convenience store, barbershop, medical and dining facilities, an underground reservoir containing millions of gallons of water, a chapel, 35 miles of telephone lines, and six 1,000-watt generators. It is a supercomputing and electronic command post linked with several military communications networks around the globe and is reportedly connected via tunnel to Camp David several miles to the north near the town of Thurmont.

Notes:  Mine inspector Glenn E. Berger reported in 1944 to his superiors that the Dixonville mine disaster which “killed” 15 men was not the result of a cave-in, but rather an attack by underground creatures capable of manipulating the earth [partial cave-ins], whose domain the miners had apparently penetrated.

Most of the dead miners were not injured by falling rocks but showed signs of large claw marks, others were missing, and one survivor spoke of seeing a vicious humanoid creature that was ‘not of this world‘ within an ancient passage that the miners had broken into. The creature somehow created a “cave-in“, blocking himself and another inspector [who closed his eyes when he felt the creatures ‘hot breath’ on his neck] from the main passage until another rescue party began to dig through the collapse, scaring the “creature” away.  Read Story here

Location: New Kensington Pennsylvania
Functions: Unknown
Levels: Unknown
Tunnels to: Unknown
Notes:  A creature, about 4 ft. tall, walking on two feet and “half humanoid – half dinosaur” was seen by grownups and children. One boy attempted to grab the creature from behind, which let out a squealing or screeching sound and escaped. Also, children attempted to pour gasoline on the creature and light it, unsuccessfully, before it escaped into a “sewer tunnel” nearby.

Location: Pittsburgh Pennsylvania
Functions: Unknown
Levels: Unknown
Tunnels to: Unknown
Notes:  Two boys enter a cave in a Pittsburgh suburb that was uncovered by road excavation work, only to find a partially buried thermal bore [a perfectly round fused polished shaft apparently melted through the rock], partially concealed by dirt, and which they uncover and explore. Their dog runs down the sloping shaft, which is about 4 ft. in diameter, ahead of them until a deep, vibrating sound is heard, following which the dog came running back out of the shaft, clawing its way over them and in total terror, running back home. The cave was then subsequently covered by further road excavation. Also rumors of old robber gangs in frontier times who would rob banks and escape to hide away in ancient caverns underground, via an “automatic door” they had discovered in the cliffs.
