Or around caliche/dry lake beds (especially when on that last stage of drying when everything starts to rot).

First, an impermeable caliche layer prevents water from draining properly, which can keep roots from getting enough oxygen.

The soil contains a lot of caliche, or clay, which gets very slick when mixed with water.

Many major urban areas in the western US have a layer of caliche under the surface.

There's a nasty layer of natural concrete called Caliche about a meter below the surface in much of the area.
