Calling tar sands development a project of “total destruction,” members of the Nez Perce tribe placed their bodies before a ‘megaload’ of extraction equipment for the second night in a row Tuesday, temporarily halting the convoy as it makes its way along Idaho’s Highway 12 to the Alberta tar sands fields.

Roughly 50 protesters from the Nez Perce tribe, Idle No More, Wild Idaho Rising Tide and other environmental groups halted for over an hour the 255-foot long, two-lane-wide shipment—the bulk of which was a 322-ton water purification unit being pulled by a big rig.

The Spokesman-Review reports:

In an action the previous evening, a group over 250 activists linked arms in a human chain across the roadway, successfully holding up the parade of vehicles for three hours. According to Wild Idaho Rising Tide, the blockade was the longest lasting “since the first tar sands extraction modules rolled from Lewiston area ports on February 1, 2011.”
