Travois:
A travois, from the French word travail, “to work,” was a device used for transportation by the Plains Indigenous peoples. Drawn by horses or dogs, the travois carried people’s goods to and from hunting sites and temporary settlements. [The Canadian Encyclopedia]
Noted in “Researchers find evidence of ancient ‘transport technology’ in New Mexico,” Erin Blakemore, WaPo:
Researchers think the grooves are the remnants of tracks left behind by “travois,” an ancient transport vehicle used before the invention of the wheel. The travois appear to have been made of poles that were either joined together at one end or crossed in the middle. Their users would have loaded them up with bulky objects, then grabbed the poles and dragged them behind them — similar to using a wheelbarrow or rickshaw with no wheels.
