Mount Baker-Snoqualmie Forest Service spokeswoman Renee Bodine said Friday that no one was hurt in the May 31 debris flow but it poses a danger since stream water can continue to move the material and additional flows can occur.
The Bellingham Herald reports (http://is.gd/v3U5Fp ) the problem is believed to have been caused by saturated sediment from the receding edge of Deming Glacier on the southwest side of Mount Baker.
The spokeswoman says the Ridley Creek and Elbow Lake trails cross the Nooksack's middle fork in the debris area. Since floods washed out bridges on those trails in 2003, hikers have to ford the river.
She recommends hikers avoid the area.
