Rescuers have named her "Tahoe." She's five pounds and about 10 weeks old.
The rescue workers have no idea where she came from or how she was separated from her mom, but they say she's lucky to be alive.
"Somebody was compassionate enough to take the time and pick her up and bring her down," said Cheryl Millham with Lake Tahoe Wildlife Care. "This is what keeps me going after 37 years. This little girl now will have a chance to grow up to be a healthy, normal little bear."
The animal rescue hopes Tahoe will grow to 90 pounds in the next year and they hope to return her to the wild.
