A search continues for a woman who went missing while on a hike in the Colfax area on Friday.

The Placer County Sheriff's Office said the search began before 6 p.m. Friday in the area of Codfish Falls Trail when deputies received a call about a woman who may be missing.

Deputies said the woman was last seen walking on the trail with her dog. The dog was later seen alone.

During the search Friday night, the woman's vehicle was found in the area and her phone and a dog bowl were found along the river. 

The dog has since been located and is safe.

Boats were on the water Sunday, but deputies said the woman has not been located. As of Sunday, deputies said there was no evidence that indicated anything other than an accidental incident. All possibilities are still to be evaluated, the sheriff's office said. 

Cal Fire, Auburn State Recreation Area and Cal OES are all assisting in the search.
