-After a light snowfall, that occurred in Devon, England, during the night of February 8th, 1855, a series of hoof-like marks appeared in the snow. These 'footprints' continued throughout the countryside for a total of over 100 miles, and, although veering at various points, for the greater part of their course followed straight lines. 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.
This "phenomenon" became known as The Devil's Footprints and is still present around the world today, however it is now attributed to Hopping mice. The print left behind after a mouse leaps resembles that of a cloven animal, due to it the motions of its limbs when it jumps.
Some contend it remains a mystery to this day, although it has been suggested that some bizarre meteorological phenomenon was at work. 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. Others have connected the footprints with the contemporaneous sightings of Spring Heeled Jack, a mysterious figure known for his extraordinary jumps.
Spring Heeled Jack is a character said to have existed in England during the Victorian era. The first recorded claimed sighting of Spring Heeled Jack occurred in 1837. Later sightings were reported from all over England, from London up to Sheffield and Liverpool, but they were especially prevalent in suburban London and later in the Midlands, where they peaked between the 1850s and 1880s. Although some unconfirmed reports claim that he could still be active, he is generally believed to have disappeared after 1904, the year of the last recorded incident. Many theories have been proposed to ascertain his nature and identity, none of which have been capable of clarifying the subject completely, and the phenomenon still remains unexplained.
