Grizzly 1058, a 5-year-old male offspring of the well-known Grizzly 399, was discovered deceased in Grand Teton National Park on May 6th. The cause of death was determined to be a vehicle strike. The bear's body was found approximately 125 yards from U.S. Highway 26, east of the Buffalo Fork River, suggesting it succumbed to its injuries after moving away from the road. The incident has raised concerns about wildlife safety in the area, especially following the death of Grizzly 399 herself in a similar collision in October of the previous year.

The death of Grizzly 1058 highlights the ongoing challenges of balancing wildlife conservation with human activity in the Greater Yellowstone Ecosystem. The fact that both Grizzly 399 and now one of her offspring have died due to vehicle collisions underscores the need for increased vigilance and potentially stricter regulations regarding speed limits and traffic management in critical wildlife habitats. The incident is likely to fuel further debate about the impact of tourism and development on the region's grizzly bear population. The high number of deaths among Grizzly 399's cubs, many due to human-related causes, raises concerns about the long-term viability of this iconic bear family and the broader grizzly population.

I honestly feel like I got punched in the stomach.

Rest in peace 1058, son of 399, my favorite of the quads. You were so full of life and independence. Cut down before your time like your mother, struck by a vehicle. 399, I am so sorry we failed you again.

We need to do better.

The death of Grizzly 1058 is a tragic reminder of the dangers faced by wildlife in areas with high levels of human activity. The incident has reignited discussions about wildlife conservation and the need for drivers to exercise caution and adhere to speed limits in the Greater Yellowstone Ecosystem. The investigation into the collision is ongoing, and it remains to be seen whether any charges will be filed. The loss of Grizzly 1058, following the death of his mother Grizzly 399, underscores the importance of ongoing efforts to protect the region's grizzly bear population and minimize human-wildlife conflict.
