Welcome to the Upper Green River Valley of western Wyoming. Lying at the southern edge of the Greater Yellowstone Ecosystem,
the Valley provides critical range for wintering wildlife -- including elk, pronghorn, mule deer and sage grouse -- and is home
to the longest big-game migration route in the lower 48 states.

The habitat rich Upper Green also holds significant energy resources, with abundant pockets of natural gas locked deep below the
surface of the valley. The valley now produces more than $3 billion in natural gas each year and accounts for nearly a quarter of all
Wyoming production.

With this placemark file, you can learn about the valley's drilling operations, investigate some of the environmental concerns that
accompany gas and oil development, and see for yourself the impact that drilling has on the landscape.

There are two ways you can learn about the issues facing the Upper Green River Valley:
