PORTLAND, Maine (NEWS CENTER) -- A few Mainers have headed to North Dakota to join the Standing Rock protest.

Thousands of people have tried to stop the Dakota Access pipeline from being built underneath a lake there.

It's near land sacred to Sioux Native Americans living on a reservation in the area.

A few people from Maine's Penobscot nation are still at the protest with another one planning to return.

“It's simple, it’s a basic necessity,” said June Sapiel, one of the Penobscots who went to Standing Rock.

Thursday night some of the protesters attended an event about the demonstration in Portland.

One woman from Kennebunkport actually came to the presentation right after a plane trip from North Dakota.

“I literally just got off the plane,” said Lara Carlson. “I've been sleeping in a field, in a three-season tent, in the middle of North Dakota in mid-November.”

Both of those women plan to return to Standing Rock as soon as they are able to.

The pipeline construction is at a halt right now because the US Army Corp of Engineers needs to make some final approvals for the project before it can proceed.
