On Sunday, the Army Corps of Engineers backed a motion for a temporary restraining order halting further construction. A federal judge ordered an emergency hearing, which will take place later today.

Standing Rock Sioux and protesters from at least 100 Native American nations and their supporters discovered Energy Transfer Partners construction crews had decimated sacred burial sites and historic and culturally significant landmarks early Saturday morning — less than 24 hours after the tribe had filed court documents concerning sacred sites.

The tribe’s historians had not been permitted onto the private property until recently to assess whether the area held cultural or other significance.

When demonstrators attempted to peacefully block crews from further destruction, security guards, or rather, mercenaries pepper-sprayed, tear-gassed, and indiscriminately sicced attack dogs on the crowd. Six people were bitten, including a pregnant woman and a young child, who reportedly had to be hospitalized.

In court documents supporting the temporary restraining order, Tim Mentz, Sr., the Standing Rock Sioux Tribe’s longtime former historic preservation officer, reiterated his filing of the newly discovered sacred sites in the path of pipeline construction on Friday, and described how crews had deliberately razed the entire area. Mentz wrote:

“From where I stood along the road, I could see that a significant portion of the site we’d surveyed had been cleared. My son walked the length of the site and confirmed that the entire area that we had surveyed that week had been graded to a depth of more than a foot.”

Mentz requested but was denied permission to assess the scope of damage. Even from a distance, however, he said, “what I have been able to see is that any site that was in the pipeline corridor has been destroyed. Sites that are immediately adjacent to the pipeline corridor are buried under berms of soil and vegetation that are as high as eight to ten feet. Anything under those berms is damaged if not destroyed.”

As Mentz explained, shallow graves in which the dead are buried under rock cairns are common in this area — thus even the relatively shallow one-foot depth the crews removed likely disturbed a number of gravesites.

Mentz — like other protesters, advocates, and observers — suggested retributive, deliberate foul play on the part of the pipeline construction company in the decimation of these sacred sites, as he described the nearest active construction area being located some 20 miles away. He and others believed that construction was in no way imminent anywhere near the area he’d surveyed — in fact, in a court filing, Mentz mapped and pinpointed precise areas of concern to the tribe.

“I do not believe the timing of this construction was an accident or coincidence,” he stated. “It appears that DAPL drove the bulldozers approximately 20 miles of uncleared right of way to access the precise area that we surveyed and described in my declaration” to the court.

Cheyenne River Sioux Tribe, which has been allowed to intervene in the ongoing court battle, also filed an emergency motion for a restraining order on Sunday, stating, with emphasis added,

“Site Protectors of all ages, outraged at Dakota Access’s clear intent to engage in construction while knowingly destroying sacred sites identified earlier in the week, attempted to halt construction and preserve evidence. In a calculated response, Dakota Access hired a paramilitary security force to attack the site protectors, including women, children, and the elderly with vicious and dangerous breed dogs, such as Pit Bulls and German Shepherds, not trained for security service. Dakota Access paramilitary squad used canisters of tear gas, and pepper spray against the site protectors. A number of site protectors were injured by the pepper spray and gas, and bitten by the vicious attack dogs.”
