Ice Age Fossils

About Ice Age Fossils

Officially announced in January of 2017 as part of Governor Brian Sandoval’s “Explore Your Nevada Initiative”, this 315 acre park features a portion of the upper Las Vegas wash that is rich in both paleontological and historical resources. During the Pleistocene, also known as the Ice Age, the wash provided verdant habitat for several species of now extinct mammals, including Columbian mammoths, American lions, camels, dire wolves, and ground sloths. The discovery of abundant fossils onsite triggered a long history of scientific research, which includes the famous “Big Dig” of 1962-3, the largest inter-disciplinary scientific expedition of its kind up to that point.

Megafauna Trail: This 0.3-mile trail has life-sized sculptures that reveal the lives and behaviors of the massive animals that once roamed Tule Springs. The trail begins near the back patio of the visitor center and ends between the visitor center and restroom building.

Las Vegas Wash Trail: This 1.5-mile trail begins and ends at the Monumental Mammoth. Hikers will experience the natural forces that created and reshaped this landscape over the course of millennia as they hike through the Upper Las Vegas Wash. The park is dry most of the year but always check with park staff for current wash conditions.

Big Dig Trail: This 1.2-mile trail begins and ends at the Trench K Trailhead. This trailhead is accessible by a 0.5-mile connector trail from the Megafauna Trail. Relive the discoveries of past scientists while hiking through trenches bulldozed by the Tule Springs Expedition. The park is dry most of the year but always check with park staff for current conditions in the wash and the trenches.

History of Ice Age Fossils State Park

At the peak of the last Ice Age, roughly 25,000 years ago, the Las Vegas area was wet and green. Marshlands extended across the valley floor. Looking out over the vegetated landscape, herds of Megafauna, like ancient bison, camels, and Columbian mammoths, would have been a common sight.

Over time, the land began to change. The wetlands were drying up, leaving behind spring-fed streams as the area transitioned to today’s arid landscape. By the end of the last Ice Age, the large animals that once called this place home were disappearing. It was around this time, roughly 12,000 years ago, that humans began leaving their mark in the valley. The earliest known human inhabitants of the valley would have walked alongside the remaining megafauna. Read More
