Just FANTASTIC !!! Incredible graphics in several different media*, they show the hills, Mountains, Valley's, plateaus and faults, in ways that reveal how Idaho came to be what it is today. Rich in history, there is information on the early miners (including women miners), the incredible Wealth taken from the Earth's crust, even Earthquakes and how crust "movements" have changed the surrounding areas. *In addition to a huge wall map that shows the state in bold 3D Relief, there is an Excellent touch-screen display that goes from an overview, down to incredible detail on each of the mining districts and individual mines (with great old pictures of the buildings, people and equipment they used). The docents were very knowledgeable and great at sharing their wealth of knowledge !!! All this and Free admission !!!!
