(Linn County, OR) -- A man swimming at the base of Tamolitch Falls, also know as the Blue Pool, died on Friday. Witnesses say the 21-year-old Kansas man jumped into the water and struggled to swim. People tried to help him reach shore, but they were unsuccessful. The Linn County Sheriff's Office says while Blue Pool is beautiful, the water temperature is 37 degrees and can cause immediate shock. Cell coverage is weak in the area and it can take hours to reach a hospital.
