Kingman Serpent
While the giant serpent of Kingman County is often linked with Sinkhole Sam, there are enough differences to give it its own page. It's far from a well know cryptid, despite having quite the tale to go with it. The creature terrorised the area around Kingman Swamp throughout the late 1960s. Size estimates ranged from 10 feet long and as big around as an arm, all the way up to 20 feet long and as thick as a human torso. Raymond Dunbar, one of the farmers who sighted it, described the giant snake as being a dirty brown color with shiny skin.
Game of Snake and Mouse
In 1969, Kingman dentist, Dr. N. E. Allison organized a hunt for the giant snake on August 10th of that year. Dr. Allison kept hearing about reports of the creature year after year and decided to finally try and do something about it. Raymond Dunbar was one of the first to spot the serpent, sometime around 1963. He said he had spotted the creature in his pasture, and watched it slither back into the swamp. He described it as being 10 to 15 feet long, and implied that he had seen the snake multiple times. Another farmer, Bill Milford, was chasing cattle on horseback, when the snake tripped his horse. An unnamed truck driver said that he spotted the snake slithering across the road, and claimed that he stopped his truck because he though the creature may damage his truck. There is also a story often attributed to the Kingman Serpent, claiming that it had killed a calf and dragged it into the swamp, however I found no report of this in any of the newspapers. August 10th came around, and over 750 people showed up for Dr. Allison's little snake hunt. There were both professional and amateur snake hunters, people on horseback, and even two planes searching the area for the elusive snake. In the end, the hunt turned up nothing. Dr. Allison led a second invesigation in 1970, with similar results, ending the giant snake terror in Kansas once and for all.
What was the Creature of Kingman Swamp?
While it's fun to think that the Kingman Serpent may have been Sinkhole Sam himself or a beast of the same species, there's a far more likely answer here. It's very likely that the creature patrolling Kingman County was simply a know snake, though one not in its natural habitat. Likely a Burmese Python or Boa Constrictor. It could have also been an Anaconda, but the size and color fits a Burmese Python best. However there's still always the chance that it really was some giant creature unknown to science, but of course that's very unlikely.
