A photographic essay by Mark Duggan.

I lived about three blocks from the Animas when it happened.

Wastewater Waiting
Crowds gather on the 32nd Street bridge in Durango, awaiting the arrival of heavy metals-laden wastewater. It would arrive at the bridge hours later, in the middle of the night.
At Trimble Crossing
Mine wastewater reaches Trimble Crossing north of Durango on the evening of August 6, 2015, more than 24 hours after the mine blowout.
Sludge Coat
Orange sludge clings to the river bottom at Trimble Crossing north of Durango, the night after the mine leaked 3 million gallons of wastewater into the Animas watershed.
Morning Comes
By the morning of August 7, the Animas River in central Durango was a bright orange, the result of heavy metals in the mine wastewater. (Photo courtesy of Stasia Lanier)

Durango residents saw a normal-colored river at sundown on August 6, by the morning of the 7th, it looked like this. (Photo courtesy of Stasia Lanier)
Rushing Wastewater
The Animas River, carrying three million gallons of mine wastewater, tumbles over rocks in downtown Durango.
Closed!
Health officials banned people from getting in the water as they assessed the risk from mine spill runoff. The Animas would stay closed for more than a week.
Gunk on the Rocks
Shallow pools and falling water levels created many orange sludge pools along the banks of the river.
Rim View North
The Animas River, off-limits to human use as the orange wastewater passed, has a long history of carrying pollution from abandoned upstream mines.
Rim View West
The river gradually changed from orange to green, before finally clearing more than a week after the mine spill. The Gold King Mine is about 60 miles north of Durango.
Standing Sickly
Rocks along the banks of the river are coated in an orange muck. It would take several weeks, and a few good rains, to wash it away.
Empty Lot
The 32nd Street boat launch parking area is usually packed in August. This was nearly a week into the river being closed to all human use.
Pea Green & Sullen
The whitewater Park, normally bustling with rafters and kayakers in August, is deserted just days after the river was closed to human access.
Warning!
The county health department was clear about the risks of getting into the river as the wastewater passed.
One Week Later
The orange tint had turned green a few days after the mine spill, but it took more than a week for the water to clear and return to a normal color.
Pale Green Ribbon
The Animas River flows through Durango one week after a mine blowout sent more than 3 million gallons of wastewater downstream.
Safe! We Think.
The Animas was declared safe for human use nine days after the mine spill. Here’s the river just hours after the closure was lifted. It took awhile for many people to venture back in.
First In
A man rides a stand-up paddleboard on the Animas, hours after health officials re-opened the river to human use. The only person I saw on the river that day.
