In the early 1900s, paleontologists unearthed the Age of Mammals when they found full skeletons of extinct Miocene mammals in the hills of Nebraska -- species previously only known through fragments. At the same time, an age of friendship began between rancher James Cook and Chief Red Cloud of the Lakota. These two unprecedented events are preserved and protected here... at Agate Fossil Beds.
Summers can be very warm, high 90's to 100 with the frequent afternoon thunderstorms. Plan to hike early and come down from the higher points if storms threaten. Winter temperatures can dip as low as -20 with snow and wind. Heaviest snows can be expected in late Spring.
