Racetrack Lignende is an experimental phenomenon observed on a granite dry lake in the Racetrack Playa, located in Death Valley National Park, California. This geological event involves the movement of large rocks, some weighing up to 110 pounds, across the dry lake surface, creating unusual linear marks or "trackway" patterns, often extending for hundreds of feet.

The rocks involved are typically oval-shaped or keystone-shaped granite boulders. Scientists have conducted research on this phenomenon to determine the possible causes behind it. A 2013 study found that an interaction between strong winds and non-uniform substrate would result in these characteristic trackways. The combination of the substrate's surface irregularities and the shear force exerted by the wind causes the boulders to move erratically, producing the trackway patterns.

Another study published in the American Geophysical Union's Journal of Geophysical Research: Earth Surface in 2017 used data from GPS stations and weather stations to further understand the wind conditions and substrate dynamics at play. Researchers found that during periods of high wind speeds, the trackways formed due to a combination of linear and non-linear movements of the stones.

The Racetrack Lignende phenomenon serves as an intriguing example of how the forces of wind and substrate interactions can create an unusual landscape feature. Further research on this event can lead to a deeper understanding of the complex relationships between wind, geology, and topography, ultimately shedding light on the intricacies of these atmospheric and geological processes. The dense, obsidian sand in the area also presents a visually striking backdrop for these tracks, capturing the attention of researchers and visitors alike.
