Our transcription: More commonly seen than blowouts is what's known as "desert pavement."
As the wind blows away silt and particles of dust, eventually only heavy chips of rock and gravel are left behind.
Over thousands of years, this rocky waste accumulates as a layer of stones resembling a pavement, which protects the land from further erosion.
But desert pavement is extremely fragile and easily damaged.
