Search and Rescue crews have been looking for two missing 13-year-old boys in the Butte Meadows area since Thursday night.
They are Kyle Saunders and his friend, Emiliano. Emiliano's last name was not released.
The boys were last seen at about 4:00 p.m. near the Cherry Hill Campground in Butte Meadows when they left to go tubing.
They went on a tubing trip that was supposed to take about 30 minutes, but they never came back.
Saunders' father, Ruben Saunders, got worried and called for help before he went looking for them.
"I'm just hoping my son comes back with his friend," said Saunders.
CAL FIRE said they are concerned about the boys being wet and wearing only their swimsuits with temperatures dipping into the low 50's.
Search and Rescue teams were activated at about 8:30 p.m. Crews said they are searching along creek beds and in meadow areas. A K-9 unit has been brought in to assist with the search.
Saunders is described as a white male, 5'9", and last seen in a blue or grey swimsuit. Emilio is described as a Hispanic male.
