U.S. Journalist Found Alive in Congo; 5 Others Are Killed

KINSHASA, Congo — Five Congo park rangers have been found dead and an American journalist has been found in good condition in the Okapi Wildlife Reserve after going missing during a militia attack, a local official said Sunday.”The American journalist is safe and healthy. She hid in the forest during an attack,” Mambasa territory administrator Alfred Bongwalanga told The Associated Press. “On the other hand, five park guards have been killed.”Bongwalanga said the army found the American overnight Saturday, and called in her rescue. He did not have her name, saying other details would follow. The identity of the assailants is not known, he said.At least 10 people had gone missing after attacks near a security station Friday outside the town of Mambasa in Congo’s northeast Okapi Wildlife Reserve, but six of them, all Congolese rangers, were later found alive, he said.Continue reading the main story […]

Honor the Buffalo Soldiers ‘John Wayne’ Legacy in Our National Parks

“Discovering the Buffalo Soldiers in the archives at Yosemite was like stumbling into family you don’t know you have, in a foreign land.” Ranger Shelton Johnson’s description in our newsletter, Pickup & GO!, in the late 1990s was ringing through my mind as I thought about how I could most effectively respond to this e-mail: “The National Park Service is studying the role of the Buffalo Soldiers in the early years of the National Park System. Our study team is collecting information from the public to better understand the Buffalo Soldiers and their work as it relates to our national parks, current efforts to tell those stories, and opportunities to enhance and further commemorate Buffalo Soldier history.” Comment here. The Buffalo Soldiers were instrumental in protecting Yosemite and Sequoia National Parks at the turn of the 20th Century when the Army ran the parks, before the establishment of the Park Service in 1916. Wow!! Did I have an earful for them!! It’s like being asked how you’d like to honor your greatest heroes of all time. Frank and I have encountered such a preponderance of evidence of the contributions of Buffalo Soldiers in National Parks from Alaska to Texas that I could hardly wait to share with the Park Service in hopes that they will share it with the world.

DAPL: A Victory Of The Great Spirit

“They claim this mother of ours, the Earth, for their own use, and fence their neighbors away from her, and deface her with their buildings and their refuse.” -Sitting Bull (Powder River Council Speech, 1875) Despite mainstream media‘s lukewarm coverage and plenty of naysayers, the eight thousand protestors at Standing Rock Sioux Reservation were vindicated today when the Army Corps of Engineers announced that it would not issue a permit for the DAPL to pass underneath the dammed section of the Missouri River. First and foremost, let’s take a bow for those standing with Standing Rock since Sioux Tribal Coordinator LaDonna Brave Bull Allard-whose father and son are buried there-cofounded the protest at Sacred Stone Camp in April. Even the bitter cold and snow of the past week and the threat of approaching major snow storms has done nothing to break the resolve of the protestors. Let us celebrate these people; the local Sioux, the Cherokee that came from as far as the Carolinas and the social activists of all backgrounds who tweeted, posted and went live day after day from Standing Rock. The Sioux have been the heart and soul of the protests; this is their victory more than anyone else’s […]

Tens of Thousands Join Protests Against Dakota Access Pipeline

Tens of thousands of people joined protests against the Dakota Access Pipeline in all 50 states and in Washington, D.C. on Tuesday, looking to send a clear signal to President Obama: respect Indigenous rights and reject this project. #NoDAPL Rally in San Francisco Many of the protests took place at offices of the US Army Corps of Engineers, the federal agency who must grant or deny the final permit for the pipeline. On Monday, the Army Corps delayed the project so that they could enter into further consultation with leaders from the Standing Rock Sioux Tribe, but refused to deny the permit outright. “All across the country, we are bringing the proverbial fires of the Oceti Sakowin to the doors of the US Army Corps, demanding action to stop this bakken oil pipeline,” said Dallas Goldtooth, Keep it in the Ground Organizer with Indigenous Environmental Network. “Now’s the time for the White House administration and its Department of Army to support Indigenous rights and sovereignty by rescinding the pipeline permits and ordering a full EIS. We all stand in solidarity with Standing Rock, because we know this is a fight worth winning.” #NoDAPL Rally in New Mexico The rallies began early in the morning in San Francisco, where more than 4,000 people surrounded the Army Corps of Engineers office. Actions continued across the country, from Kansas City to Bangor, Maine. In many places, people connected the fight against Dakota Access to their own local struggles against fossil fuel infrastructure and injustice […]

President Obama says the Dakota Access pipeline could get rerouted.

In an interview with the website NowThisNews, Obama told the host, Versha Sharma, that the Army Corps of Engineers is examining whether the pipeline project can be moved elsewhere.

“As a general rule, my view is that there is a way for us to accommodate sacred lands of Native Americans,” Obama said.

The Obama administration halted construction on a section of the pipeline in early September. The Standing Rock Sioux Tribe has resisted the proposed pipeline because it would run over sacred burial sites and dangerously close to their water supply.

Dave Archambault II, chair of the Standing Rock Sioux Tribe, welcomed Obama’s comments. “We applaud President Obama’s commitment to protect our sacred lands, our water, and the water of 17 million others,” he said, in an email statement. Archambault said he believes that the Obama administration “will do the right thing.”

Obama says it will be “several more weeks” before his administration figures out whether the dispute can be resolved in a way “that’s properly attentive to the traditions of the first Americans.”
