Waco Mammoth National Monument

The Waco Mammoth National Monument is a paleontological site and museum in Waco, Texas, United States where fossils of 24 Columbian mammoths (Mammuthus columbi) and other mammals from the Pleistocene Epoch have been uncovered. The site is the largest known concentration of mammoths dying from a (possibly) reoccurring event, which is believed to have been a flash flood. The mammoths on site did not all die at the same time but rather during three separate events in the same area. A local partnership developed around the site after the initial bone was discovered. The Waco Mammoth Foundation worked in partnership with the city of Waco and Baylor University to develop the site. Baylor's involvement mainly included the research, preservation, and storage of materials from the site, while the city of Waco contributed to the protection of the land.[3] In 2015, they successfully sought the National Monument designation to bring the expertise of the National Park Service into the partnership.[1]

History

Depiction of a Columbian mammoth

Columbian mammoths lived 10,000 to 1 million years ago. They migrated to North America and as far south as Nicaragua. The Columbian mammoth was a herbivore, with a diet consisting of varied plant life ranging from grasses to conifers.[4] At this time, the Central Texas landscape consisted of temperate grasslands and savannahs surrounded by river floodplains.[5]

How the animals at the site died is unknown, but there is no evidence that humans were involved. The current theory is that approximately 68,000 years ago, at least 19 mammoths from a nursery herd were trapped in a steep-sided channel during a flash flood and drowned and/or were buried by mud. A camel was also trapped and killed during this event. Later floods buried the remains. A second event took place sometime later. During this event, an unidentified animal associated with a juvenile saber-toothed cat (genus Smilodon) died and was buried. The third event claimed the lives of a bull mammoth, two juvenile mammoths, and an adult female. Approximately 15,000 years after the nursery herd was trapped, these animals also appear to have been victims of rising water, unable to escape due to the slippery slopes of the surrounding channel.[6]

The age of the fossils was determined using Luminescence dating, specifically optically stimulated luminescence (OSL), of the sediment. OSL uses light to excite electrons and cause the emission of photons. The photons can be sensed and measured to calculate when the sediment was last exposed to the sun. The soil near the mammoths' remains was examined using OSL to determine how long the minerals were buried. As the soil was buried at the same time as the mammoths, determining when the soil was last exposed to the sun would correlate to the time when the mammoths perished.[7]

Discovery

The site was discovered in 1978 by Paul Barron and Eddie Bufkin, who were searching for arrowheads and fossils near the Bosque River. The men found a large bone and took it to the Strecker Museum at Baylor University for analysis. Once the bone was identified as Columbian mammoth, the museum staff organized a formal dig at the site. Between 1978 and 1990. In 1979 Sr. George F. Naryshkin (then an undergraduate at Baylor) began work on his 2 1/2 year excavation and study of the site. George went on to become a dentist( graduating from Temple Dental School in 1986)and is a veteran Air Force Pilot who now practices dentistry in Florida.

He asked for and received permission from the owners of the property to excavate the area. George named the site "The Waco Mammoth Site" and uncovered 5 mammoths at the time and in 1980 completed his senior thesis on the site titled "The Significance of the Waco Mammoth site to Central Texas Pleistocene History". He aged the site to about 40,000 before present based on terrace dating. Following his graduation, 16 mammoths were discovered. These first remains were protected with plaster jackets and stored at the Strecker Museum (now the Mayborn Museum Complex). The other remains were excavated between 1990 and 1997. These remains include a large male (bull), a female, two juveniles and a camel (Camelops hesternus) and are in situ at the site.[6]

Though the first bones at the site were discovered in 1978, the site remained closed to the public until the end of 2009. That year, a shelter was completed to protect the bones and allow the site to be viewed by the general public. The site, now run by the City of Waco, Baylor University, and the National Park Service, sits in a 100-plus acre stretch of wooded parkland along the Bosque River.[6]

National Monument

United States Representative Chet Edwards filed legislation in 2010 to make the site a National Monument and include it as a unit of the National Park Service.[8] The bill passed the House of Representatives but died in the Senate. Representative Bill Flores filed a similar bill in 2012. Again, the bill passed the House of Representatives but died in the Senate.[9][1]

On July 10, 2015, President Barack Obama used his authority under the Antiquities Act to designate the site as Waco Mammoth National Monument, to be managed by the National Park Service in collaboration with the City of Waco and Baylor University.[10] Members of the National Park Service and United States Forest Service and Secretary of the Interior Sally Jewell surrounded President Obama as he signed the executive orders in the Oval Office. The city has deeded the 5-acre dig site to the federal government but retains 100 acres around it for future park-related development.[11]

Features

Geography

The Waco Mammoth National Monument is found in Waco, Texas. The location of the monument lies on along the Bosque River, within 100 acres of wooded parkland.[12] It is theorized that due to the proximity to the river, the deaths of the uncovered prehistoric animals were a result of flash flooding, drowning the creatures about 67,000 years ago. Land erosion further cemented the mammoths along with several other mammals of the time, into the depths of the earth.[13]

Attractions

The Waco Mammoth National Monument is the site of the only known remains of a herd of "Columbian Mammoths"[14] The site also includes "in situ" fossils of a camel, a bull mammoth, and female mammoths. The fossils are "in situ", meaning that they are still in the original place of initial discovery. The monument stands as one of the largest single herd non-death sites in the world.[15]

Youth involvement

The National Monument provides opportunities for the youth to participate. The Waco Mammoth National Monument allows field trips, group tours, and the opportunity to become a "Junior Ranger". Through completing activities throughout the park, the visitor can be sworn in as a Waco Mammoth National Monument Junior Ranger.[16]

gollark: Just enumerate all possible strings in order, silly.
gollark: Or "possibly TC but you can't know unless you throw ridiculously insane amounts of computing power at it".
gollark: Hmm, perhaps if you make it use the most recent likely-true-but-hard-to-prove maths problem somehow...
gollark: The twin prime conjecture, say?
gollark: For "probably TC but very hard to prove", maybe tie it to unsolved maths problems?
