He was outfitted with a GPS radio collar after being captured in the central Santa Monica Mountains as a ``subadult'' in December 2019, then traveled west and crossed the 101 Freeway at the Conejo grade, spent some time in Wildwood and then crossed Highway 23 and then Highway 118.
Researchers determined that the mountain lion would cross beneath the I-5 Freeway along the Santa Clara River, and even went way up into the Angeles National Forest before returning to the Santa Susana Mountains.
Biologists had re-captured him last November in the eastern Santa Susana Mountains -- where he had been living -- to replace his GPS collar because the battery was due to fail soon. It is not clear when he was born, according to the National Park Service's website.
