Note of interest: Wolverines? In July, 2010 our caretaker, returning at night to our property on foot from the South Weed truckstop area, stumbled across an animal that he identified (at the time and again after looking at photos) as a wolverine. It seems improbable as confirmed wolverine sightings are extremely rare. However, there have been a number of fairly recent unconfirmed reported sightings in the Mt. Shasta area and Shasta-Trinity forest of the California Wolverine (Gulo gulo luteus), a sub-species, once thought to be extinct in the state. So who knows? For more info see the link below:
