The US has many treaties with native american tribes they just plain ignore. The courts are about to change many things in our country because of it.
The government should have negotiated with tribes many years ago but chose to stick their head in the sand and pretend treaties were not binding. Well the courts say they are so get ready.
Wyoming now must allow tribal hunting on non inhabited lands in the Bighorns. I bet many more tribes will be stepping up to claim their rights based on treaties the government chooses to interpret for their benefit not the tribes.
