Landslides continue to threaten small debris flows and muddy floods in the upper reaches of Middle Fork Nooksack River. The U.S. Forest Service warns hikers to stay away from the Ridley Creek and Elbow Lake trails located in that area on the Mt. Baker-Snoqualmie National Forest and forest rangers have posted warning signs at the trailheads.
According to Hydrologist Carolyn Driedger, this is the only area of concern. “Rocks are slick with mud and more debris flows from small water impoundments can occur,” she said. Driedger is with the USGS Cascades Volcano Observatory in Vancouver, Wash. The activity is being caused by the debris flow two weeks ago from the Deming Glacier on the southwest side of Mt. Baker.
