About this image:
During the 1800's, the area now known as Wyoming became the focus for western expansion. The discovery of the South Pass route over the Rocky Mountains was the primary reason for the location of the Oregon, Mormon Pioneer, California, and Pony Express Historic Trails in Wyoming. Karen and her father, noted artist Bill Carr, created a number of murals and illustrations for the NHT Interpretive Center.
