The salt flats were used for the exterior of the Lars homestead on Tatooine. The interior was filmed in Hôtel Sidi Driss, which is located in Matmata, 300 kilometers away.
Lucasfilm and crew returned here to shoot the Tatooine sequences for Attack of the Clones and Revenge of the Sith. The sets from the original movie—which had been taken down—were rebuilt in 2000 to the exact specifications from the original plans, on the exact same spot and with attention to detail to recreate the very same building as from twenty-five years earlier.
The site was renovated by fans between 2010 and 2012. The man-made craters are still there.
