The sand forms stripes in the hills. This happens because the colors settle into layers on their own. This is a strange way for sand to act. You can see this at home too. If you mix colored sands, they will eventually separate.

How did these colors start? They came from volcanic rock called basalt. Over time, the rock broke down into clay. Then, a way called total hydrolysis changed it into soil.

Two main parts in the soil make the colors. Iron makes red or dark colors. Aluminium makes blue or purple colors. The colors may come from how the hot rock cooled down. Rain has carved patterns into the hills. These patterns look like earthen meringue. People visit to see the view. You can look from a wooden fence. You must not climb on the dunes.
