According to the US Census Bureau, the county has an area of 1,907 square miles, of which 1,899 square miles is land and 7.4 square miles is water. The highest point in the county is Thompson Peak at 10,751 feet, on its eastern border in the Sawtooth Wilderness. Established February 4, 1864 with its county seat at Idaho City. Named for the Boise River, which was named by French-Canadian explorers and trappers for the great variety of trees growing along its banks. The Boise Basin, in which Idaho City lies, was one of the richest gold mining districts in the nation after the discovery of gold in 1862. The first gold was discovered on 2 August 1862 near Centerville. It wasn’t long before settlements were born all over the basin. One of the first was Bannock City in December 1862. The Idaho Territory was created in March, 1863 and Bannock City was renamed Idaho City in 1864. Idaho City had the many standard problems of a gold rush town with lawlessness, revelry, excitement and gold fever itself. It is said that out of 200 burials in the local Boot Hill Cemetery, only 28 deaths were from natural causes! Idaho City’s worst enemy was fire that first struck on 18 May 1865. Other fires followed, each time destroying most of the town. Lucky for Idaho City, great wealth was in place due to the gold. The city was rebuilt after every fire. Only a few buildings were saved with each event. During its heyday, Idaho City was the largest city in the entire northwest US. More gold came out of this area than from all of Alaska. Many abandoned mines and diggings may still be seen today.
