Pronghorn Buck in Snow : Prints Available

 A member of the Teton pronghorn herd stands in fresh autumn snow at Antelope Flats. The first snow of the season started the pronghorn moving on their annual migration to the Upper Green River Basin, a journey over 120 miles. It is the longest land mgration in the lower 48 states and some pronghorn travel up to 170 miles for winter range. After spring calving, the Teton herd returns to the National Park.

A new article about the Path Of The Pronghorn in the Billings Gazette indicates that the fabled Teton herd is suffering losses due to gas drilling on their winter range in the Upper Green River Basin. Marla and I made a trip to Pinedale in December to document the “Mule Deer Crash” of the Pinedale herd. Pronghorn disperse throughout the basin and depend heavily upon windswept slopes to survive the harsh winter. There’s no denying that the decision to drill on critical winter range for both mule deer and pronghorn is heavily impacting both species. Is it worth risking extinction of pronghorn in a National Park?
