Edwards filed legislation in 2010 to make the site a National Monument and include it as a unit of the National Park Service. 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. 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. 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. 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. 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. Attractions The Waco Mammoth National Monument is the site of the only known remains of a herd of "Columbian Mammoths." The site also includes "in situ" fossils of a camel, a bull mammoth, and female mammoths. The fossils are "in situ", meaning they are in the original place of initial discovery. The monument stands as one of the largest single herd non-death sites in the world. 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.
