The glacier carved ponds of North Dakota are referred to as ‚"potholes‚". The potholes
and surrounding mixed-grass prairie held multitudes of ducks, shore birds, courting birds, migrating birds, nesting birds, birds, birds, birds. Sadly, less than one tenth of one percent of the original tall-grass prairie remains. No other ecosystem on the continent has been more compromised. And yet, you got a sense of it touring round the potholes... of how it might once have been.
