White Sands National Park- mammal and human tracks

White Sands National Park: mammal and human tracks in Alamogordo, New Mexico

Leave a comment

White Sands National Park is a premier fossil viewing location in Otero County, New Mexico. The site exposes Pleistocene fossils where visitors can view for mammal and human tracks.

Collecting is strictly prohibited in national park – viewing only. Some tracksite locations are accessible to public with ranger guidance, but most tracksites are protected active research areas not open to visitors. Excellent visitor center and museum with exhibits. Ranger programs discuss the fossil discoveries. Park entrance fee charged. The primary attraction is the spectacular gypsum dunes; fossil tracks are secondary and mostly for scientific research. The human footprints represent groundbreaking evidence in the study of early human migration to the Americas.

White Sands National Park protects the world’s largest gypsum dune field (275 square miles). Recent discoveries of Pleistocene human and Ice Age mammal tracks in ancient lake bed deposits have made international headlines and pushed back evidence of human presence in North America. The tracks date to approximately 21-23 thousand years ago during the Last Glacial Maximum, making them among the oldest evidence of humans in the Americas.

This complete guide covers everything you need to know about fossil viewing at White Sands, including directions to the site, collecting rules and regulations, the types of fossils you can find, and what to expect during your visit. Alamogordo provides the nearest services and amenities for visiting collectors.

Location and Directions

You can find White Sands in Otero County, New Mexico.

Directions to White Sands

To reach White Sands: Park at the entrance off Highway 70 west of Alamogordo; visitor center provides information on current tracksite locations. When you arrive, the fossil collecting area is located at various Pleistocene tracksite locations within the park (locations vary and many are protected research areas).

What Fossils You’ll Find

Fossil collectors visiting White Sands can discover mammal and human tracks. The site contains Pleistocene fossils preserved in ancient lake deposits now covered by gypsum sand dunes. Visitors can find both Ice Age mammal tracks and Human footprints from the ice Age at this New Mexico location.

Geologic History

The fossils at White Sands formed during the Pleistocene.

Millions of years ago, the area that is now Alamogordo, New Mexico was cooler and wetter than today’s Chihuahuan Desert, with a large pluvial lake (Lake Otero). Modern climate is arid desert.

As these ancient organisms died, sediments buried and preserved their remains. Over millions of years, geological processes transformed these sediments into the fossil-bearing rocks visible at White Sands today.

How White Sands Became a Fossil Collecting Site

White Sands was established as a protected area to preserve fossil resources while providing public access for education and collecting. Recognition of the site’s paleontological importance led to its designation as a managed collecting location.

Park or preserve status protects White Sands from commercial exploitation while maintaining access for hobbyists and researchers. This management approach ensures fossil resources remain available for future generations while allowing current visitors to experience the thrill of discovery.

Collecting Rules & Regulations

Is Fossil Collecting Allowed?

White Sands does not allow fossil collecting for visitors.

Tule Springs Fossil Beds National Monument-

Tule Springs Fossil Beds National Monument: megafauna such as mammoths, ground sloths, camels, and horses in Las Vegas, Nevada

Leave a comment

Tule Springs Fossil Beds National Monument is a premier fossil collecting location in Clark County, Nevada. The site exposes Pleistocene fossils where visitors can hunt for megafauna such as mammoths, ground sloths, camels, and horses.

Collecting is strictly prohibited in national monument – viewing only. Visitor trails and interpretive areas explain the fossils and Ice Age environment. Focus is on education, interpretation, and ongoing scientific research. The monument protects crucial evidence of Ice Age ecology in the Mojave Desert region.

Tule Springs became a National Monument in 2014 to protect important Pleistocene mammal fossil sites in the Las Vegas Valley. The area has produced numerous Ice Age mammal fossils including Columbian mammoths, Shasta ground sloths, extinct camels, and ancient horses. Archaeological evidence also shows human presence near the end of the Ice Age.

This complete guide covers everything you need to know about fossil collecting at Tule Springs Fossil Beds, including directions to the site, collecting rules and regulations, the types of fossils you can find, and what to expect during your visit. Las Vegas provides the nearest services and amenities for visiting collectors.

Location and Directions

You can find Tule Springs Fossil Beds in Clark County, Nevada, at the North side of Las Vegas.

Directions to Tule Springs Fossil Beds

To reach Tule Springs Fossil Beds: Find monument access from northwest Las Vegas area; check NPS website for current visitor information and access.

When you arrive, the fossil collecting area is located at various Pleistocene fossil localities within the monument (mostly protected).

What Fossils You’ll Find

Fossils at Tule Springs Fossil Beds date to the Pleistocene. Mammals and petrified woord are the most commonly found fossils at this Las Vegas, Nevada site.

Geologic History

The fossils at Tule Springs Fossil Beds formed during the Pleistocene.

Millions of years ago, the area that is now Las Vegas, Nevada was an ancient wetland and spring complex. The climate during the Pleistocene was significantly cooler and wetter than the modern Mojave Desert, with extensive wetlands and perennial water sources supporting diverse megafauna and vegetation.

As these ancient organisms died, sediments buried and preserved their remains. Over millions of years, geological processes transformed these sediments into the fossil-bearing rocks visible at Tule Springs Fossil Beds today.

Observing Fossils Found at the La Brea Tar Pits

Leave a comment

Background:

The pits are composed of heavy oil fractions called gilsonite, which emerged from the Earth as oil. These deposits had become topped with water, dust, and leaves. Animals would venture in and become trapped, luring predators who come to eat the animals and become trapped themselves. The thick tar then encases the bones, preserving them remarkably well.

Paleontology:

The preserved organisms in it are mainly from the Pleistocene epoch, although a great deal of finds date from prehistory (10 kya — 4 kya). Saber-toothed cats, mastodons, ground sloths, bison, western horse, and camelids are . Dire wolves are the most common large land mammal found there.

The La Brea Tar Pits Museum has made a beautiful timeline of the creatures found in the tar pits here.
