sandy

Residents of Datu Blah Sinsuat, a coastal town known for its white, sandy beaches and clear waters, frequently get their food from the sea.

Less than 1 meter away on the same sandy surface, three isolated prints head north.

The adjacent, more jagged lakeshore cliffs generate weaker and less distinct echoes, while the more or less contemporary dwelling sites on the sandy shores of the same water bodies have no audible echoes at all.

The result, if we want to get really geeky, is a mix of clay, pure sand and sandy loam.

Not everything, though -- studies of the sandy soil have turned up diverse microbial communities.
