The Secret Government Installation in South Mountain Maryland

If you’ve never heard of the secret government installation in South Mountain, Maryland, then today I would like to introduce you to the legend and the conspiracy. Most people have heard of the amazing Civil War battles that took place in and around South Mountain. The state was a major flash point between the Union and Confederacy.

General Robert E. Lee invaded Maryland in September 1862 in his bid for Harper’s Ferry. Union Major General George McClellan countered in Federick, Maryland before heading to South Mountain. The historic mountain itself became an epicenter of fierce battles, particularly in Crampton’s, Turner’s and Fox’s Gaps mountain passes. During these battles, countless soldiers on both sides died upon the mountain. Considering the historic and military importance of the site, it is no surprise that there are rumors of a secret government installation in South Mountain, Maryland.

Where is the Secret Government Installation in South Mountain, Maryland?

Why would anyone make the claim that there’s some sort of secret facility within this mountain? That’s easy – northern Maryland, and specifically two or three of the large tracts of land are suspected by most locals of being secret government installations. There are several reasons for this – but most importantly due to the numerous “black” helicopters (actually dark army-green) traveling throughout the area.

There are also dead giveaways, like heavily secured areas with guards and monitored gates the likes of which you would never expect around a normal “communications” tower. Camp Ritchie was built by the Maryland National Guard in 1926. It included 638 acres and named after the governor of Maryland at the time. Throughout 1942, South Mountain was used by the War Department as the American training ground to prepare U.S. troops for fighting conditions in Germany.

South Mountain Maryland Installation

Almost 20,000 World War II troops were trained there, including a significant number of intelligence personnel. In 1944, the Army invested over five million to expand the complex to house thousands of personnel (including even captured war criminals from Germany and Japan.) It was also a major counter intelligence training facility for the OSS (Office of Strategic Services).

The fort was an impressive, sprawling military complex, with homes, training facilities and many other buildings spread out over many acres. The vast tract of land west of the fort served as an ideal, secluded training area for military exercises.

During the cold war, the facility became “Fort Ritchie.” However, post Cold-War cutbacks led to the facility shutting down in 1998. Today, the entire area of Northern Maryland is rife with alleged secret government facilities, mostly underground locations bristling with dishes, antenna and communication towers. What’s interesting about these claims is that when you examine the massive communication tower (named WAYZ) at the top of South Mountain, it’s very apparent how isolated the facility is.

There are three access roads, one dirt road from Fort Ritchie, one dirt road from the southern part of Range Rd, and one paved from the North. As you zoom in closer to the facility, you can see the amazing size of the tower (check out the length of that shadow) and the various transmission dishes and second communication towers around the facility.

As you can see there’s the massive tower (red/white) in the center, a dish array on the southern side, and other smaller towers throughout, such as the one on the northern side of the site. The largest building and tower is surrounded with fencing around the perimeter.

This is the closest overhead view of the massive tower and the facility. The half-full parking lot indicates that this is a fairly busy facility with a decent staff. It definitely lends some credit to the stories that the facility was a cold war microwave transmission facility.

The “AT&T” Facility at Hearthstone Mountain

Another interesting facility a bit west and a little north of Fort Ritchie is the well-protected underground facility over at Hearthstone Mountain. This facility is revealed best by a local hiker writing about the Bear Pond mountain range. The hiker reported that Cross Mountain has a communication antenna that was allegedly used to send microwave signals during cold war. However, the fascinating facility is the one set up on Hearthstone. The entrance gate attempts to convince visitors that it’s just an AT&T research facility.

And his snapshot from the air is just as interesting (click on either photo to visit the hiker’s website.)

A closeup of the facility using Google maps satellite imagery is even more revealing.

Notice the AT&T logo painted on the helipad? It’s like a signal straight up to the sky for foreign spy satellites to see – like a message that screams, “Look, see – we’re just an innocent research facility owned and operated by AT&T….no secret U.S. government research going on in any underground bunkers here!” I wonder what genius thought up that one.

Zooming in as close as possible, you can see the thick concrete entrance (there’s one on each side of the massive underground bunker) where there are doors big enough for large vehicles to drive into (like the bulldozer sitting outside this one). If this is truly an “AT&T Project Center” – they better produce a much better model of my Windows Mobile phone if they’ve got this much money to throw at a research facility!

Observing these areas from the ground is virtually impossible. The second facility is surrounded (according to the hiker) by remote cameras all around the gate, and very likely throughout the land that surrounds it. Local members of the community report black helicopters all throughout these region of Maryland, so it isn’t at all surprising to find facilities like this nestled in the middle of remote tracts of land.

What do you think, a simple private research facility or one of the governments secret underground installations? Share your opinion in the comments section below!

    not much here to get excited about…..AT&T has facilities like this all across the USA, not just near DC. Hardened microwave dishes that are on the ground are made of concrete, built to survive a nuke blast…..just silly, C.O.G. stuff paid for by our tax dollars….like we’ll all want to get on the phones after the start of WWlll

    South of Boonsboro ,Md. there is another area! It’s at the end of Lambs Knoll Rd., that starts just feet from the monument to fallen Civil war Gen. Reno. You can drive right up to the top of the mountain till you get to a fence with signs that read “U.S Goverment -No Tresspassing”. You can check it out on google maps. A very large water storage tank, a microwave tower and what looks like a uhf/vhf antena. Also a medium sized office building and very large parking lot.

    I’m Curious!

  • Thanks for your comment Monet! That does look like another interesting facility. You can often determine the importance of the facility by the size of the parking lot. 🙂

    A lot of the sites in Maryland with the huge Antenna equipment are old WWII era microwave facilities that (allegedly) have been converted or modified to other uses.

    We’re hoping to cover some of the declassified documents from that era that maybe will shed some light on some of the older activities around this area.

  • Monet

    The Lambs Knoll Rd. location went up last winter. It was lit up at night, like there was a car lot up there. Everything there appears new. The road leading up to the location seems oddly perfect.

    Also, there appears to be a trail running northwest on the the Google map satellite image. It leads to a house on a road below the site. Drove too the location where the house should be. It doesn’t seem to match the satellite image at all. I think the trail in the satellite image is a trench dug for some kind of utility.

    None of this places are secret. Anything that is secret regular citizens don’t know where it is…period.

  • Dellsom

    I know I would want to get on the phone. It’s more than making phone calls.

  • Obviously, an secret underground bunker would need a secret retaining wall to hold back the secret soil.  Perhaps it is simply the excretions from secret underground Meerkats?  They live underground in sparsely populated areas, so they must be government agents.

    THis is very interesting…

  • sstyx

    Interesting! There is more to this area but you already know this. A simple google of the base will give you answers to many of your questions……

    there are three of these places within 75 miles of each other in the md, pa, wv area. i live in halfway and frequent the areas they are in. i have seen at two seperate times with my own eyes convoys of federal cars and state troopers escorting planes much like the stealth unmanned aircraft leaving the location in clear spring. i also have driven past the warning at high rock park in cascade and greeted by armed guards telling me to turn around or else. the south mountain one is virtually unaccesible. i have a brother in the intelligence post at aberdeen proving grounds. i am also ex-military

  • J

    I have been in this facility. Nothing too spectacular. They did cover all computer screens and dry erase boards prior to letting me in certain rooms however. The majority of the rooms seem to be for storage of food and for bunks.

  • Cool – thanks for sharing. That’s interesting!

    I live in nearby Myersville and grew up in the area. I have traveled the access road from Reno Monument Rd. and taken it up to the gate with cameras. I pressed the button and was greeted “can I help you?” I said, “I’m here for the tour of the missile silo” lol. He said he didn’t know what I was talking about. I laughed and put my car in reverse and went on my way. In high school we threw bonfire parties a quarter mile away from the facility in the woods. Good times. We would see random government-plated vehicles traveling along the road all the time. As far as the dark colored army helicopters are concerned, they fly rampant around here. Some days it’s louder in the sky than others. They are bearing North from the south mountain facility which may suggest they are heading towards to at&t facility and others nearby. Also, they fly extremely low altitude which may also suggest a quick flight. There is definitely classified activity going on here. It’s blatant. I find it interesting!

  • I was up on top of Hearthstone Mountain in 1964 when my father was working for the contractor (Consolidated Engineering, Inc. of Baltimore, MD – now defunct) as a construction engineer building the facility for AT&T.
    He told me some intriguing stories back then (I was 9 years old) about those massive entrance doors (3 ft. thick solid concrete between steel plates) and other oddities that were part of the project: like jet engine turbine generators for electricity.
    The official design drawings had a few “intentional errors” he discovered (he was anal about dimensions and details!) – like exactly where do the microwave antennae in those concrete “bunkers”, on top and visible, actually point? (Microwaves travel by line-of-sight, and do not “spread out” light normal radio waves.)
    He’s long gone now (d. 1988) and No Such Agency knows who I am – they told me to, “Never come back here.” when I stumbled onto their turf last year and ended up detained briefly. (I had made a right turn across the street from a new Booz, Allen and Hamilton building in a very high-tech business park while looking for an expressway entrance – really!).

    @Bis: You can drive up to the gates on Hearthstone Mtn. quite easily – it’s hard to miss!

  • Interesting! Thanks for sharing.

    I live right here in Frederick, MD, just east of South Mountain, and have lived here all my life. Some things you got spot on, and others, you have a bit off or missed a key factor. The main thing you missed is that the big deal behind South Mtn is not the communication towers, but the ballistic missile silo on Lambs Knoll. My dad delivered newspapers there when he has a young teenager, and it was undergoing heavy construction during the cold war (circa mid-1970s). After and during the construction, he was stopped at the gate, but prior to that, they’d let him come onto the property/base. During construction, the top of the mountain was blown off and replaced with concrete, and there’s thought to be a large underground base beneath. After all, check on Google Earth, doesn’t it seem that the parking lot is way too large for the few buildings nearby?

    Despite what some folks will tell you, the missile silo is not a lookout tower. From looking at it, this seems obvious, but some disagree for some reason.

    The South Mtn/Lambs Knoll Complex was one of several missile sites (I’ve been told there were 50, but have only managed to find a dozen or so today) that were designed to surround Washington D.C. in case of an attack, and shoot down any incoming missiles from other places before they hit D.C. There’s hardly any traffic in or out today, and as far as helicopters are concerned, I doubt there’s been any landing on the mountain in 10 years.

    You are correct about the many military bases in the area, even a few lesser known ones. They’re in about a 35-mile radius around Frederick. It’s a key location due to its proximity to D.C. and previous military bases. Basically, After Fort Richie and Fort Detrick were here, it just made sense that more bases should be nearby as well. It’s almost like they were an unofficial joint base between several of the armed forces and some other US security forces.
    >Fort Detrick was started sometime around WWI as a small military base and an airfield for observation biplanes, but has become a huge medical facility research center. The previous airfield on base is long gone, as are all the aircraft, except the occasional helicopter.
    >Also in the area, just a 20 minute drive north, is Thurmont, and just west of that, is Camp David, the presidential retreat. Basically it’s where Mr. Pres gets to invite all the dignitaries and his friends to have meetings whenever the White House is inconvenient or he can’t handle the beltway traffic.
    >Lastly, there’s Raven Rock Mountain Complex, or “Site R”, located about 6 miles north of Camp David. It’s also known as the “Underground Pentagon”. More information can be found on it’s Wikipedia page, and at least the first snippet about it in the intro is true. Site R can be noted as one of the first (if not the first) underground nuclear bunkers built to house personnel from Washington, along with high ranking brass from every american force but the Coast Guard (sorry guys). The Cheyenne Mountain Complex in Colorado was designed after Site R in part, with necessary modifications being made. During the Obama Administration, Site R has been opened up and tours are allowed in the underground part, even though it is still highly active and kept secret (kinda ironic that they allow tours in a top secret base). This is according to the official White House website. They also have some neat information of the base. The link is provided here:
    >And then of course we had the South Mtn/Lambs Knoll Complex, which we already discussed.
    So you can see there were a lot of installations around here, and there still is to this day. All but Fort Richie are active, although there is limited use at the Lambs Knoll Complex. I suspect that’s because they stay underground most of the time and come up only to resupply and switch out people.
    Most of the “dark green helicopters” are either coming from or going to either Camp David, or Fort Indiantown Gap, up near Harrisburg, PA, where there’s a large helicopter base. They also fly over while doing exercises from Aberdeen Proving Grounds on the east side of Baltimore or occasionally from Davidson Army Air Field, Mananas Regional Airport, both in VA, or every now and then from Joint Base Andrews. Chinooks are enroute to Martinsburg Air National Guard Base in WV, or to Dover AFB, DE.

    *In response to annon’s statement, I honestly don’t think he lives in the area. I know where Clear Spring is, out past Hagerstown, and as far as I know, there’s nothing out that way. “Convoys of federal cars” are never around here in my experience, other than military convoys passing thru on the highways, as far as “state troopers escorting planes much like the stealth unmanned aircraft”, that’s complete BS. While the Maryland State Police do own several aviation units, they do NOT escort any military aircraft, EVER. I’d imagine the helicopters probably fly too slow to maintain speed with jets anyways, much less alleged unmanned stealth aircraft. Those types of aircraft are only flown over Southern Cali as far as I know, the closest you could get to that statement being true is if you went down to the Chesapeake Bay on a day when they’re testing a F-35 (they fly out of Patuxent River NAS). The only creditable thing I can see here besides his first sentence is where he says “i also have driven past the warning at high rock park in cascade and greeted by armed guards telling me to turn around or else”. Right there is where Fort Richie is, but it closed in 1998 as a military installation. Currently I believe it’s still government-owned and they’re storing mass computer data on-site there, and underground, much like the cloud, but for more secure government purposes. So, that much might be true.

    Anyways, I know that was a heck of a lot, but it’s all good stuff, hope it was helpful!

  • Very helpful feedback from a local — really appreciate that. Thank you!

  • Todd Smith

    Years ago, I was a delivery driver throughout the western Maryland area. There is another AT&T “communication
    station” on top of the mountain outside Clearspring. The access road was called Hanging Rock rd. That place had armed military guards at the top of the mountain as well. Look it up on google earth and you’ll see the same AT&T logo on the parking lot. There are several odd looking buildings around the grounds and a huge underground gate that I could see from the main gate.
