It is known that this horse was registered twice with Aphc. This registration was recorded with unknown sire and dam. Snake Rivers T220160 is the registered sire of Minidoka Snowy Britches, but Snake Rivers Bonanza T92002 is not the registered sire of Minidoka Snowy Britches. Per ApHC records, Snake Rivers T220160 is by an unregistered Appaloosa sire and unregistered Appaloosa dam. If a pedigree is ran, it will show this. This was confirmed by Terry Hutton of the ApHC in 2015.
