Five of the seven locations were included in Thursday's vote. They were renamed in consultation with tribes and local communities.
In California, one site was renamed Loybas Hill, which was proposed by the Paskenta Band of Nomlaki Indians and means "young lady"
Another California site was renamed Yokuts Valley, which translates to "people"
A North Dakota site was renamed Homesteaders Gap, which was selected by the community because it was relevant to local history
In Tennessee, a site was given the name Partridgeberry, a plant for which the community was named before
A location in Texas was renamed Lynn Creek in honour of Isaac Lynn, a man who lived on the creek nearby
Of the remaining two sites, one in Wyoming was removed from consideration because it is now privately owned land, while another location in Alaska was removed because it is a historical area that no longer serves an unincorporated community, the government said.
The move comes as several private companies and sports teams in recent years have also decided to rename teams or remove terminology and imagery considered racist toward Native Americans.

It does matter for a lot of people to get this right. >

For some people a name is all they have. Names are important. 
This is definitely a step in the right direction.
