Depending on the impurities embedded within it, the salt from WIPP can be anything from a reddish, relatively opaque rock to a clear crystal like the one shown here.

The salt, ordinary sodium chloride, makes for an effective repository because it creeps over time to entomb the waste and protect against radiation exposure.
