Overview
- Park wildlife staff lethally removed a black bear near Delta Lake after days of escalating encounters and difficulty deterring the animal, tranquilizing and euthanizing it in the remote backcountry and flying the carcass out the next morning.
- Officials say visitors repeatedly left food or allowed the bear to get human food, a pattern they blamed for conditioning the bear to approach people and for making hazing unusually ineffective.
- Park managers monitored reports about the bear earlier in the year and increased efforts when sightings rose, but determined that translocation and other nonlethal options were not safe or likely to stop the behavior.
- The backcountry location limited quick intervention and complicated removal logistics, factors that influenced the decision to perform on‑site euthanasia after other methods failed.
- Grand Teton officials warned visitors that even one food reward can change bear behavior and urged people to secure food and belongings immediately if a bear approaches to prevent future conflicts.
