If only the sandstones could sing, imagine the stories they'd tell, of dinosaurs, mammoth hunters and the "ancient ones" known as the Anasazi.

All roamed southern Utah over the eons, long before Native Americans struggled to hold their land against Mormon settlers, modern life and now, Donald Trump.

As the President arrives in Utah Monday afternoon, this rocky corner of the Wild West is a battlefield once again, but this time the warriors will carry briefcases and lawsuits.

Trump, by signing two presidential proclamations on Monday, shrunk the size of Bears Ears National Monument by more than 80% and Grand Staircase-Escalante National Monument by roughly 45%, fundamentally reshaping the two large national monuments.

The proclamations split the two national monuments into several smaller sections. Bears Ears will be shrunk from 1.35 million acres to 228,337 acres, according to the spokesperson for Interior, and split into two separate monument sections. Grand Staircase-Escalante, a monument designated by President Bill Clinton, will be split into three sections and shrunk from 1.9 million acres to just about 1 million acres.

Trump slammed past administrations -- namely Clinton's and President Barack Obama's -- for what he called "federal overreach." The two former Democratic president designated Bears Ears and Grand Staircase-Escalante for protection, hoping to preserve their culture, history and natural beauty.

Past administrations, Trump said, thought "the natural resources of Utah should be controlled by a small handful of very distant bureaucrats located in Washington. And guess what? They are wrong."

"The families and communities of Utah know and love this land the best and you know the best how to take care of your land," Trump said. "You know how to protect it. And you know best how to conserve this land for many, many generations to come."

Locals in the area saw the designations as nothing more than a 3-million-acre federal land grab. The drillers, miners and frackers who were shut out by Clinton's and Obama's use of the Antiquities Ac t would have new leases on life. Sen. Orrin Hatch and his fellow Utah Republicans would have a major victory to celebrate.

Hoodoos are among the natural wonders in Bears Ears National Monument.

But those who believe the rocks can talk, through countless fossils, sacred ruins and desert solitude, are bracing for a fight.

"I'm going to sue him," says Yvon Chouinard, founder and CEO of outdoor gear maker Patagonia. "It seems the only thing this administration understands is lawsuits. I think it's a shame that only 4% of American lands are national parks. Costa Rica's got 10%. Chile will now have way more parks than we have. We need more, not less. This government is evil and I'm not going to sit back and let evil win."

Chouinard led the effort to move a major outdoor show from Salt Lake City to Denver in protest of Utah's land use politics and he's been a big supporter of the historic coalition of the five local tribes, which put aside ancient rivalries and lobbied for monument protection.

Outdoor retailer Patagonia also lent its voice in opposition to the move Monday, setting the home page of Patagonia.com to a blacked-out page that says, "The President Stole Your Land," with the option to learn more about "the largest elimination of protected land in American history."

The site also gave visitors the option to support groups that are pushing back.

Interior Secretary Ryan Zinke said he was unmoved by people like Chouinard who are threatening lawsuits.

"I don't yield to pressure, only higher principle," he said. "And I don't think public policy should be based on the threat of lawsuit ... I feel very confident."

San Juan County Commissioner Phil Lyman says the designation of Bears Ears as a national monument never felt right.

But Chouinard's arguments carry no sway at a pro-Trump, anti-monument rally in Monticello. Here, Chouinard represents all the liberal interests from outside, conspiring to pit neighbor against neighbor. "What's his net worth? One billion dollars? Two billion?" says San Juan County Commissioner Phil Lyman. "You got Patagonia in here waving the flag of environmentalism while he's completely exploiting the outdoors for industrialized tourism. For a person in that position to try and lecture morality to one of the poorest counties in the entire nation is wrong."

There has been opposition to Bears Ears as a monument since it was designated.

The size of New Jersey, San Juan is the biggest and poorest county in Utah and with this moment of political victory, Lyman finds kinship with the coal miners of Appalachia.

He points out that Bears Ears is the fifth national park or monument in his county and argues that oil and gas extraction would have less impact on the landscape than the brand of adventure tourism that has transformed nearby Moab. "By designating a monument, you are using a tool that will bring hordes of people to a place that is very sensitive," he says.

But according to former county commissioner and Navajo elder Mark Maryboy, cultural sensitivity is hard to find in San Juan County. "They didn't want to work with us," he says. "In fact, one of the county commissioners told me 'You guys lost the war so you have no business talking about the land planning process.'"

With efficient strides, he drops into a canyon near the San Juan River, past one of the 100,000 sacred ruins in Bears Ears, to a wall covered in 1,200-year old rock art. The spindly renderings of man and animal are the work of an artist they've dubbed "Wolfman" for the paw print signature that accompanies the pictoglyphs. And then he points out the modern bullet holes.

Ancient rock art is pockmarked by bullet holes.

To his Navajo faith, this canyon holds the spirits of his loved ones and these carvings are just as sacred as any art in the Vatican or any wall in Jerusalem, yet someone has been using it for target practice.

"The local white community members are determined to get rid of all the art rock," he says. "It stands in the way of progress for them. It stands in the way of a job. New cars. New clothes. Rolex watch."

He's heard the argument that his people need jobs and that the extraction industry could provide them while protecting the most important sites.

Native Americans built grain stores and other structures in what is now southern Utah.

But, he feels, history hasn't shown that to be true.

"The experience that Native Americans see in this county is discrimination," he says. "They are the last ones to be hired for any position. Even if there's a huge mining operation opening up, they will not be hired for that position. And they will be exposed to the toxic materials that are left on the ground or in the air."

Regardless of Trump's decision and unless Utah politicians can figure out a way to take them back and sell them off, the 3 million acres around Bears Ears and Grand Staircase-Escalante will remain public.

If you are an American, this is your land and these are your rocks. Pay them a visit sometime. You'll be amazed at the stories they tell.
