Craig Springer, M.Sc., M.A. is a fish biologist for the U.S. Fish and Wildlife Service - External Affairs , stationed in New Mexico. He can see from his front porch where Spaniards documented the first trout in the New World in 1541 as their entrada skirted the Sangre de Cristo Mountains. The Rio Grande cutthroat trout would wait another 315 years to get a scientific name. Springer can't wait each spring to catch cutts in the high country with his kids. His conservation stories have appeared in the New York Times, ESPN and Farmers ' Almanac.
