Construction crews blowing up parts of a national monument to make way for the US/Mexico border wall could be on the verge of destroying sacred burial sites, an Arizona congressman has said.
But Representative Raúl Grijalva, an Arizona Democrat, said he's still hoping the crews will change course before it's too late.
"You can't replace these things. You can't fix them once they're gone," Mr Grijalva told CNN.
"And as someone that grew up in the borderlands, it's painful to know that this is occurring."
Controlled blasts began inside Arizona's Organ Pipe Cactus National Monument last week, according to Ned Norris Jr, chairman of the Tohono O'odham Nation, which is adjacent to the monument.
US Customs and Border Protection (CBP) confirmed in a statement that blasts had started in the area.
"The controlled blasting is targeted and will continue intermittently for the rest of the month," CBP said.
"US Customs and Border Protection will continue to have an environmental monitor present during these activities as well as on-going clearing activities."
Organ Pipe Cactus National Monument is a park that encompasses more than 800 square kilometres in southern Arizona, bordering the Mexican state of Sonora.
On the National park Service website, it's described as an International Biosphere Reserve with a "thriving community of plants and animals."
The Tohono O'odham Nation is a federally recognised tribe with about 28,000 members on tribal lands in southwestern Arizona.
Mr Grijalva said the blasting occurred last week in an area known as Monument Hill, a place where he said Apache warriors who battled with the O'odham were laid to rest.
He said officials appear to be fast-tracking wall construction to score political points rather than heeding serious requests from Tohono O'odham leaders.
"It's a political agenda, without worrying about consequences that could happen in terms of these sacred sites," he said.
Asked whether he'd confirmed the blasts had damaged sacred burial sites or whether that was something he feared would happen, Mr Grijalva said: "It's more of a fear, given the behaviour and given the lack of consultation, given the lack of concern.
"We hope that by putting some level of public light on this issue, it forces Homeland Security to think twice. It's all within their discretion," he said. "If they decide to do it differently, it can be done differently."
The Trump administration has waived environemental laws and other regulations to expedite border wall construction. Officials have said they "remain committed to environmental stewardship" as construction moves forward.
Laiken Jordahl, a borderlands campaigner for the Centre for Biological Diversity -- a group that's been fighting border wall construction -- said he's already documented dramatic changes in the area.
"This mountain (Monument Hill) is a sacred site to the O'odham and other indigenous people," he said.
"And it's quite literally being blown up so Trump can build the border wall across this mountain - It's just heartbreaking to watch."
At another site in Organ Pipe last month, he said, bulldozers flattened cacti in what he described on Twitter as "horrific destruction."
Mr Norris, the Tohono O'odham chairman, accused US federal officials of violating their own policies by moving forward with construction without holding "meaningful consultations."
"The Tohono O'odham Nation is adamantly opposed to the construction of the 30-foot, fortified border wall, which would irrevocably harm cultural sites, sacred sites and the environment," Mr Norris said.
"Media reports that explosives are now being used further demonstrates the massive and unnecessary destruction the wall is inflicting."
