Cannon Ball, ND The Standing Rock Sioux Tribe made a call for help several months ago in the fight against the Dakota Access Pipeline.
The movement has since grown to include thousands - and many say they'll stay in Cannon Ball, North Dakota - through the end.
Black Hills FOX reporter Robert Grant said "Many people have already been here for about 3 months, and they say they're not giving up - the next step is to gear up for the winter months."
Joe Pulliam, from Pine Ridge, said "I think as a community, as a family that we've grown into - if we put our minds together, we can survive the winter."
This Pine Ridge local is helping build a message - a 20 by 20 foot shelter made to help them survive the cold while protesting the Dakota Access Pipeline.
Soon, the building will be a cooking shack.
Madonna Thunder Hawk, from the Cheyenne River Reservation, said "There's a lot of work going on - getting ready to winterize the entire camp."
Madonna Thunder Hawk moved camp up hill to weather the storm.
Thunder Hawk said "We might have terrible storms or we might not have any - but you've got to be ready."
And she says she's not going anywhere.
Thunder Hawk said "Yeah right - we're here for the duration."
The $3.8 billion dollar pipeline travels just north of the Standing Rock Reservation with a proposed route through the Missouri River - leaving some in fear it could pollute drinking water.
Thunder Hawk said "Our stand here is simple. We're here to protect the water and the land."
Proponents of the project say it is a direct and cost-effective way to transport oil - while boosting the economy with 12 thousand jobs in the process.
It's the same cause that has brought tribes from around the world - together as one in North Dakota.
Thunder Hawk said "Extended family. And look around you - that's who's here."
Pulliam said "I also have a family here too that I have to take care of."
The protester's main camp in Cannon Ball sits in the expected path of the Dakota Access Pipeline.
Thunder Hawk expects construction crews will work their way to the site within the next few days.
