Adhesion of particles of loess allow an almost vertical angle of repose.

The reason for this adhesion is a matter of some discussion.

If saturated with water -- loess will slump.

The white objects are carbonate concretions.
Called 'Loess Kindchen' (loess children)
they were used as toys by Native Americans.

Some are hollow and rattle when shaken.
