It’s Halloween, so what better time to look at some of the creepier names in the world of volcanoes? Ever since people stared up at erupting volcanoes and thought “Huh, I guess that thing might kill me,” volcanoes have engendered a lot of fear and apprehension. So it’s no wonder that a pile of them have horrific-sounding names. Now, this list is by no means complete–I created it by looking at the Global Volcanism Program’s Holocene and Pleistocene volcano lists, so I likely missed a bunch of scary names in tongues I don’t understand. But it’s a good start, and if you have any suggestions, feel free to leave them in the comments.

Here they are: my ten best Halloween-themed volcanoes.

Jornada del Muerto, New Mexico: We’ll start off with a volcano named “Route of the Dead Men” (mostly thanks to its remote, inhospitable location). Jornada del Muerto is a small shield volcano almost in the middle of New Mexico. The whole desert Southwest is pockmarked with these small, basaltic volcanoes, likely related to Basin and Range extension across that part of the continent. Although it likely hasn’t erupted since 760,000 years ago, Jornada del Muerto is near a potential magma body located under Sorocco, so it could be a place of renewed activity sometime in the future.

Alligator Lake, Canada: Now, I suppose Alligator Lake isn’t a particularly frightening name, unless you are afraid of alligators. However, did you notice that this Alligator Lake is in Canada? You know, that country that is more-or-less bereft of the large reptiles? Something must be especially frightening about this lake to get this name. Alligator Lake is a collection of cinder cones, shield volcanoes, and lava flows in the Yukon(!) that likely hasn’t erupted since the last Ice Age. Canada is actually full of spooky volcano names, including Crow Lagoon, Dark Mountain, and Hoodoo Mountain.

Devil’s Garden, Oregon: Look at enough volcanic terranes and you’ll find a bevy of names related to ol’ Scratch himself. Devil’s Garden is another lava flow field that stretches to the east 0f Newberry Caldera in central Oregon. This area is also full of lava tube caves from these voluminous basalts that might be as young as 10,000 to 20,000 years old. Oregon also features another Devilish volcano in the Devils Hills chain on the southern slopes of South Sister, a linear array of rhyolite domes that erupted in the last few thousand years, along with the nearby and disturbing Three Fingered Jack.

Monte Vulture, Italy: Monte Vulture is a bit of an oddball. It is located to the east of the Appenines and has quite a violent history, although it might be nearing the end of its volcanic lifespan. The volcano features a caldera at its summit but no one can agree on exactly when and how the caldera was formed. Over 150 square kilometers around the volcano are blanketed by the volcanic ash and debris from its eruptions, the most recent of which occurred ~420,000 years ago.
