The senior wildlife biologist at Grand Teton National Park is retiring after 26 years on the job. During his tenure, Steve Cain worked with state and other wildlife managers to improve conditions for wildlife, not just in the park, but across the 22-million-acre Greater Yellowstone Ecosystem. Rebecca Huntington has more.
