Kittitas County Sheriff's Office is trying to find a man they say attacked a woman early Monday morning while she was camping at French Cabin Creek camp grounds in the Salmon La Sac area.

Deputies say between 1:00 and 3:00 a.m. the 25-year-old victim was sleeping outside when a man attacked her. She screamed, woke up her friend, who then helped get the man off of her. He ran into the forest.

Deputies say the suspect is a white or Hispanic man in his late 30's or early 40's. He is 6'0", 250 lbs., with long hair and was wearing a dark colored hooded sweatshirt with a possible "Under Armor" logo.

Anyone with information can call the Kittitas County Sheriff's Office at (509) 962-7525.
