The Devil's Den in Hemlock Gorge

There are lots of places in New England named after the Devil. A few years ago, I published some lists on this blog. I'm not going to repost the full list today, but I have included a list of the Bay State's devilish places at the end of this post. 

I've been to several of these places, like the Devil's Footprint in Ipswich, the Devil's Den in Ashland, and another Devil's Den in Newbury. Amazingly, though, I've never been to the Devil's Den in Hemlock Gorge, which is in Needham right on the Newton border. I've lived in the Greater Boston area for more than 30 years, but somehow never visited the devilish place closest to me.


Last weekend we set out to rectify that. Hemlock Gorge is easily accessible by the MBTA Green Line, so Tony and I filled our water bottles, hopped on the T, and were soon at the Hemlock Gorge Reservation. I have to say that this park is worth visiting even if you aren't interested in vaguely Satanic caves. It's situated right on the Charles River and has some nice walking trails, but it also has the enormous Echo Bridge, which was built in 1877 to contain an aqueduct. The bridge is only open to pedestrians and has amazing views from its top. 


We entered the reservation from the northern side. The first thing we passed was this very dramatic spillway, where water from the Charles River flows under Route 9. I'm glad I'm not a fish or a small duck because I would definitely go over those falls to my doom.


Near the spillway was this old stone barn. Since I'm a horror-nerd, at first it reminded me of the Whateley house in H.P. Lovecraft's "The Dunwich Horror," whose windows and doors have been sealed up to contain an amorphous, ever-growing, ravenous monstrosity. A closer look revealed there was indeed an unsealed door and also some open windows, and a sign indicated that the building is used for some type of scientific purpose. 



Sadly, this probably means there isn't a monster inside. I guess that's good news for the neighbors, but the barn has always been a source speculation. For example, when the barn was built in 1839 some locals thought it was going to be used to raise silkworms. That never worked out, even though silkworms are preferable to monsters.

The Devil's Den was just a short walk from the barn. I knew it was a cave of some kind, but I had modest expectations because most caves in Massachusetts are pretty small. That was not the case! It's actually large enough to stand up in, and is located on a steep embankment overlooking a pond. There's also a small, little cave right next to it which is too small to hold a human.



A lot of Massachusetts caves are formed by boulders that were piled on top of each other by the glaciers. That type of cave is called a tallus cave, but the Devil's Den is quite different. It's carved out of solid puddingstone, not formed by assorted boulders. I don't know what geological forces did this, and I'm assuming it was a combination of water and wind. 


Like a lot of weird places we've visited, there was some graffiti in the Devil's Den. Although I'm not a fan of graffiti, I can understand why teenagers would want to leave their mark in someplace named after the Devil. Many of the places we visit are just slightly off the beaten path and are good locations for teens who want to hide their illicit behavior from their parents. At least there wasn't a lot of trash or broken glass in the cave, which was nice. 

This excellent page about Hemlock Gorge says that that local Native Americans may have used the cave to dry fish, but I couldn't find any information about why it's called the Devil's Den. King's Handbook of Newton (1879) only says the following: 
Just across, on the Needham Shore, is the old rocky grotto known as the Devil's Den. This is, of course, to be expected; for poor must be the New-England town that has not its bit of a cavern, consecrated to his Plutonian Majesty. 
As that quote sarcastically notes, you really can find caves or rock formations named after the Devil in many places. But why? I've seen a few theories trying to explain this. One claims that many of these places were associated with Native Americans, and that racist settlers gave them them devilish names because they thought the Native Americans were evil. That could explain the Devil's Den in Hemlock Gorge.


Sometimes there are also legends about particular devilish places that explain how they got their name. The legends might claim a particular cave earned its sinister name because it was used by smugglers or bandits, or that a particular rock formation was literally formed by the action of the Devil (like the Devil's footprints in Ipswich and Norton). Underlying all these legends and place names are old Puritan ideas about good and evil, where things outside the norm (like strange rock formations) were considered suspicious and assigned to the Devil. 


Interestingly, Needham has two Devil's Dens - the one we visited in Hemlock Gorge, and another one in the Town Forest. I think the one in Hemlock Gorge is larger and easier to access, but I'm jealous that Needham has two Devil's Dens. I can imagine it might cause confusion, though, if you're invited to the Devil's Den for nefarious deeds (or just a hike) but the location is not specified.
