On late Sunday, Grizzly 399 was spotted with her new cub, Spirit, by seasoned wildlife photographers Tom Mangelsen and Jorn Vangoidtsenhoven. By Monday morning, the sighting was confirmed. The news spread quickly, marking another chapter in the story of this iconic bear. Mangelsen and Vangoidtsenhoven have followed 399 for years, capturing her life through their lenses and sharing it with the world.

Grizzly 399 is known for taking her time to emerge from hibernation, often appearing in April. Last year, she kept everyone on edge until mid-May before showing up with Spirit. This year, her early emergence adds to the excitement. The first grizzlies to awaken are typically the large males, but 399’s appearance is always a highlight of the season.

Spirit’s Growth

Spirit, born last year, has grown exceptionally large. Many attribute his size to being a solo cub, with no siblings to compete for his mother’s milk. This rapid growth ensures a strong start in life. Grizzly 399 has a remarkable track record with her cubs, having successfully raised a rare set of quadruplets in 2020, all of whom survived to independence.

Fame and Legacy

Grizzly 399’s fame extends beyond the wilderness of Grand Teton National Park. Her habit of bringing her cubs to visible areas near roadsides has made her a favorite among photographers and visitors. Mangelsen’s work, particularly his contributions to the documentary “399: Queen of the Tetons,” has cemented her status as a beloved figure. Despite her advanced age of 28, experts believe she will live long enough to see Spirit reach independence next year.
