The Devil's Footprints were a phenomenon that occurred during February 1855 around the Exe Estuary in East and South Devon , England. After a heavy snowfall, trails of hoof -like marks appeared overnight in the snow covering a total distance of some 40 to 100 miles (60 to 160 km). The footprints were so called because some people believed that they were the tracks of Satan , as they were allegedly made by a cloven hoof . Many theories have been made to explain the incident, and some aspects of its veracity have also been questioned.
On the night of 8–9 February 1855 and one or two later nights, after a heavy snowfall, a series of hoof -like marks appeared in the snow. These footprints , most of which measured about four inches long, three inches across, between eight and sixteen inches apart and mostly in a single file, were reported from more than thirty locations across Devon and a couple in Dorset. It was estimated that the total distance of the tracks amounted to between 40 and 100 miles (60 and 160 km). Houses, rivers, haystacks and other obstacles were travelled straight over, and footprints appeared on the tops of snow-covered roofs and high walls which lay in the footprints' path, as well as leading up to and exiting various drain pipes as small as four inches in diameter. From a news report:
"It appears on Thursday night last, there was a very heavy snowfall in the neighbourhood of Exeter and the South of Devon. On the following morning the inhabitants of the above towns were surprised at discovering the footmarks of some strange and mysterious animal endowed with the power of ubiquity, as the footprints were to be seen in all kinds of unaccountable places – on the tops of houses and narrow walls, in gardens and court-yards, enclosed by high walls and pailings, as well in open fields." 
The area in which the prints appeared extended from Exmouth , up to Topsham , and across the Exe Estuary to Dawlish and Teignmouth . R.H. Busk, in an article published in Notes and Queries during 1890, stated that footprints also appeared further afield, as far south as Totnes and Torquay , and that there were other reports of the prints as far away as Weymouth ( Dorset ) and even Lincolnshire .
There is little direct evidence of the phenomenon. The only known documents were found after the publication during 1950 of an article in the Transactions of the Devonshire Association asking for further information about the event. This resulted in the discovery of a collection of papers belonging to Reverend H. T. Ellacombe , the vicar of Clyst St George during the 1850s. These papers included letters addressed to the vicar from his friends, among them the Reverend G. M. Musgrove, the vicar of Withycombe Raleigh; the draft of a letter to The Illustrated London News marked 'not for publication'; and several apparent tracings of the footprints.
During many years the noted researcher Mike Dash collated all the available primary and secondary source material into a paper entitled The Devil's Hoofmarks: Source Material on the Great Devon Mystery of 1855 which was published in Fortean Studies during 1994.
Many explanations have been made for the incident. Some investigators are sceptical that the tracks really extended for more than a hundred miles, arguing that no-one would have been able to follow their entire course in a single day. Another reason for scepticism, as Joe Nickell indicates, is that the eye-witness descriptions of the footprints varied from person to person.
In his Fortean Studies article, Mike Dash concluded that there was no one source for the "hoofmarks": some of the tracks were probably hoaxes , some were made by "common quadrupeds" such as donkeys and ponies, and some by wood mice (see below). He admitted, though, that these cannot explain all the reported marks and "the mystery remains".
Author Geoffrey Household suggested that "an experimental balloon" released by mistake from Devonport Dockyard had left the mysterious tracks by trailing two shackles on the end of its mooring ropes. His source was a local man, Major Carter, whose grandfather had worked at Devonport at the time. Carter claimed that the incident had been quieted because the balloon also wrecked a number of conservatories , greenhouses, and windows before finally descending to earth in Honiton .
While this could explain the shape of the prints, sceptics have disagreed about whether the balloon could have travelled such a random zigzag course without its trailing ropes and shackles becoming caught in a tree or similar obstruction.
Mike Dash suggested that at least some of the prints, including some of those found on rooftops, could have been made by hopping rodents such as wood mice . The print left behind after a mouse leaps resembles that of a cloven animal, due to the motions of its limbs when it jumps. Dash stated that the theory that the Devon prints were made by rodents was originally proposed as long ago as March 1855, in The Illustrated London News .
It is also often suggested that the footprints were merely a case of mass hysteria , caused by the sighting of various animal tracks and assuming them to be the same.
In a letter to the Illustrated London News during 1855, Rev. G. M. Musgrave wrote: "In the course of a few days a report was circulated that a couple of kangaroos escaped from a private menagerie (Mr Fische's, I believe) at Sidmouth." It seems, though, that nobody ascertained whether the kangaroos had escaped, nor how they could have crossed the Exe estuary, and Musgrave himself said that he invented with the story to distract his parishioners' concerns about a visit from the devil:
I found a very apt opportunity to mention the name of kangaroo, in allusion to the report then current. I certainly did not pin my faith to that version of the mystery ... but the state of the public mind of the villagers ... dreading to go out after sunset ... under the conviction that this was the Devil's work ... rendered it very desirable that a turn should be given to such a degraded and vitiated notion ... and I was thankful that a kangaroo ... [served] to disperse ideas so derogatory...— Rev G. M. Musgrove: letter to The Illustrated London News , 3 March 1855.
During July 1855, a ' Professor Owen ' stated the theory that the footprints were from a badger , arguing the animal was 'the only plantigrade quadruped we have in this island' and it 'leaves a footprint larger than would be supposed from its size'. The number of footprints, he suggested, were indicative of the activity of several animals because 'it is improbable that one badger only should have been awake and hungry' and added that the animal was 'a stealthy prowler and most active and enduring in search of food'. 
Reports of similar anomalous, obstacle-unheeded footprints exist from other parts of the world, although none is of such a scale as that of the case of the Devil's Footprints. This example was reported 15 years earlier in The Times :
Among the high mountains of that elevated district where Glenorchy, Glenlyon and Glenochay are contiguous, there have been met with several times, during this and also the former winter, upon the snow, the tracks of an animal seemingly unknown at present in Scotland. The print of the foot in every respect is an exact resemblance of that of a foal of considerable size, with this small difference perhaps, that the sole seems a little longer or not so round; but, as no one has had the good fortune as yet to have obtained a glimpse of this creature, nothing more can be said of its shape or dimensions; only it has been remarked, from the depth to which the feet sunk in the snow, that it must be a beast of considerable size; it has been observed also, that its walk is not like that of the generality of quadrupeds, but that it is more like the bounding or limping of a hare when not scared or pursued. It is not in one locality only that its tracks have been met with, but through a range of at least twelve miles...— The Times , 14 March 1840, p. 1.
In the Illustrated London News of 17 March 1855, a correspondent from Heidelberg wrote, "upon the authority of a Polish Doctor in Medicine", that on the Piaskowa-góra (Sand Hill), a small elevation on the border of Galicia , but in Congress Poland , such marks are to be seen in the snow every year, and sometimes in the sand of this hill, and "are attributed by the inhabitants to supernatural influences".
On the night of 12 March 2009, marks claimed to be similar to those left during 1855 were found in Devon.  During 2013 trails were reported in Girvan, Scotland possibly as part of an April Fool's hoax. 
In popular culture
The Devil's Footprints was used as the inspiration for the events depicted in the motion picture Dark Was the Night . The movie speculates how a modern American town would react to discovering biped hoof prints in freshly fallen snow.
