Wolverines Keep Being Spotted Across California — And No One Can Explain Why

Wolverines Keep Being Spotted Across California — And No One Can Explain Why Wolverines were wiped out of California in 1922. A century later, they keep showing up in the Sierra Nevada anyway — and no one can fully explain how they got there. This documentary examines every confirmed wolverine detection in California in over 100 years — from "Buddy," the lone male first photographed near Lake Tahoe in 2008 and tracked across 300 square miles of mountains for a decade, to the second animal recorded three times in May 2023 in the Inyo National Forest and Yosemite, including the skier who filmed it from a gondola at Mammoth Mountain. Buddy's DNA matched the Rocky Mountains of Idaho — more than 400 miles away, across the snowless desert of the Great Basin that a snow-dependent animal has no business crossing. To this day, biologists cannot agree whether he walked an impossible route or was released by human hands. It follows the one journey that proves these crossings are real: M56, a wolverine collared in Wyoming who walked to Colorado, then to North Dakota — the first in that state in over 200 years — navigating interstates and subdivisions the entire way, before a rancher shot him in 2016. What the evidence shows. What state biologists will actually confirm. And why a breeding population is almost certainly not here — even as a species of barely 300 animals, newly protected under the Endangered Species Act, keeps pressing back toward the snowy mountains that still carry its name. A cold investigation into an animal that officially vanished from California a century ago, and the ghosts that keep crossing a desert they were never built to survive. Sources Moriarty, K.M. et al.
