Hagerman is the home of the Hagerman Fossil Beds National Monument of the U. S. National Park Service. No other fossil beds preserve such varied land and aquatic species from the Pliocene. More than 180 animal species of both vertebrates and invertebrates and 35 plant species have been found in hundreds of individual fossil sites. The Hagerman Horse Quarry fossil beds have produced 20 complete skeletons and a number of partial skeletons of this zebra-like ancestor of today’s horse.
The Hagerman Valley was formed 15,000 years ago by the Bonneville flood which gouged out canyons, moved house-sized boulders and left enormous sand bars. The Valley’s unique landscape is dotted with innumerable, rounded, “rock melons”, some the size of an automobile. The volcanic lava flows, deep box canyons, fossil beds, mine diggings and vast rock formations tell the story of days gone by. Hot springs produce warm water that can soothe your aching muscles and cold springs gush water a perfect temperature for raising trout.
Here you will see the canyon of the mighty Pohogawa, the River of the Sage Plain, as the Indians called the Snake River. You can experience its rapids, whirlpools, waterfalls and associated wildlife. It is a land of melon farming, water-fowl and deer hunting and fishing for trout.
“The Valley of the Thousand Springs” is one of those rare natural rest stops that has been serving travellers for hundreds, perhaps thousands of years. The mild, almost snowless winters, hot springs and natural fisheries provided by the clear flow of springs at a constant 58 degrees made the valley a favorite Indian wintering area.
