MARTIN, COUNTY, Fla. – Impacts from Hurricane Nicole along Florida’s Treasure Coast are being credited for unearthing what are thought to be human remains from a historical Native American burial mound that could date back to 500 B.C.

The Martin County Sheriff’s Office announced Thursday that it dispatched a team of criminal investigators to Hutchinson Island after a resident reported the finding to authorities.

Hurricane Nicole made landfall on the island as a Category 1 storm with sustained winds of 75 mph. It is only the third in recorded history to make landfall during the month of November in the Sunshine State, joining the “Yankee Hurricane” of 1935 and Hurricane Kate in 1985.

Deputies said the strong winds from the hurricane likely helped unearth at least six sets of bones from the ancient cemetery.

“Detectives are working diligently to preserve and carefully remove the remains that are exposed with the utmost care and respect. Those remains will be transferred to the Medical Examiner’s Office and then to the Bureau of Archeological Research,” the agency said.

NICOLE’S DANGEROUS STORM SURGE WASHES AWAY ROADS, BOARDWALKS ALONG FLORIDA COAST

The barrier island has been a hotbed of discoveries for decades, and archeologists believe that previous discoveries dated back to the Glades time period between 500 B.C. and 1750 A.D.

The Florida Public Archeology Network is aware of the sighting and said significant storms such as Hurricane Dorian in 2019 and other significant systems have helped unearth historical discoveries in the past.

“Florida has over 14,000 years of history,” said Emma Dietrich, an archeologist at the Florida Public Archeology Network. “It was a great place to live back then and is a great place to live today. So, it is not a surprise that people are making discoveries.”

The Native American Graves Protection and Repatriation Act dictates what will happen with the remains and requires witnesses and authorities to treat sacred objects and bones with dignity and respect.

Beachgoers who come across artifacts and other historical findings from the storm are encouraged to report them to the State of Florida at 850-245-6444 or their regional office of the Florida Public Archeology Network.

Years Before Present (BP)

Years Before Present (BP) refers to a time scale used by geologists and archaeologists among other scientists in different fields of studies to denote an event that took place in the past. January 1, 1950, is typically taken as the starting date of the time scale, indicating the 1950s as the time when scientists began using the technology of radiocarbon dating.

Radiocarbon Dating

Radiocarbon dating is a technique used to determine the age of different objects that have organic materials by the use of radiocarbon, which is a carbon isotope that is radioactive. This technique was discovered in the 1940s. Radiocarbon dating utilizes the idea that 14C (radiocarbon) is seamlessly being generated in our atmosphere through the interactions between atmospheric nitrogen and the cosmic rays. The oxygen in the atmosphere combines with the 14C resulting in radioactive atmospheric carbon dioxide that is used by plants during the photosynthesis process. The animals would acquire 14C when they consume plants. Eventually, when the plants and animals die, they stop carbon exchange with the environment. From that instant onwards, 14C continue to decrease because of radioactive decay. A sample of a dead organism like an animal or a plant can be analyzed for the remaining 14C and thereby determining when the plant or animal died. The half-life of radiocarbon 14C is 5,700 years. This is the time it takes for the quantity of 14C to reduce to half the initial value. source

“One advantage to using BP is it avoids the occasionally irate philosophical debate about whether, in this multicultural world of ours, it is more appropriate to use AD and BC, with their explicit references to Christianity, or to use the same calendar but without the explicit references: CE (Common Era) and BCE (Before the Common Era). The problem is, of course, that CE and BCE still use the estimated date of the birth of Christ as the reference points for its numbering system: the two years 1 BCE and 1 CE are numerically equivalent to 1 BC and 1 AD.

However, a major disadvantage of using BP is that the present year, of course, changes every twelve months. If it was a simple matter of counting backward, what was accurately measured and published as 500 BP today in fifty years would be 550 BP. We need a fixed point in time as a starting point so that all the BP dates are equivalent no matter when they are published. Since the BP designation was originally associated with radiocarbon dating, archaeologists chose the year 1950 as a reference point for ‘the present.’ That date was chosen because radiocarbon dating was invented in the late 1940s. At the same time, atmospheric nuclear testing, which throws huge amounts of carbon into our atmosphere, was begun in the 1940’s. Radiocarbon dates after 1950 are virtually useless unless and until we can figure out a way to calibrate for the excessive amount of carbon still being deposited in our atmosphere.” source

Weather extremes unearth human remains across US

If it isn’t a deluge of precipitation making human remains easier to spot, drought conditions in the Desert Southwest have also led to grisly discoveries.

Authorities along dwindling Lake Mead, which is located along the border region of Arizona and Nevada, have reported finding at least six sets of human remains during the past six months.

A megadrought and an increase in consumption of the country’s largest reservoir caused water levels to drop to an 80-year low during the summer.

All the remains have been transferred to the Clark County Coroner’s Office, which will be tasked with determining the deceased’s identity.
