Work at Warnick Bluff near Glacier was part of an emergency project and was completed in December. During the flooding in early November, WSDOT was forced to temporarily shift Mount Baker Highway (State Route 542) further from the river because it was eroding the bluff and compromising the stability of the roadway. The work horse of this operation was a 44-foot long Boeing Vertol 107helicopter with twin 50-foot blades. The helicopter lifted the 30-foot long logs and 9,000-pound boulders onto the stream bank below the unstable hillside. The roadway was too unstable to lower materialsdown from it directly.First, two 9,000 pound boulders are placed with each 30-foot log. Anexcavator was used to put them in position at the base of the bluff. Then crews use steel cable to connect a boulder at each end of the logs. The logs and boulders have holes drilled through them forrunning the cable through.The completed log and boulder combinations are placed perpendicular to the hillside and river. When the river rises the logs and boulders will redirect the force of the river away from the hillside and help deposit sediments near the bank.
