Nederland survived three boom-and-bust cycles involving three different
minerals. During the silver boom, U.S. president Ulysses S. Grant
visited Central City in 1873 and walked on silver bricks that had been
mined in Caribou and milled in Nederland. The second boom followed the
discovery of gold in Eldora in 1897 and lasted only a few years. The
third boom was sparked by the discovery of tungsten by Sam Conger, the
same man who made the original discovery of silver in Caribou. The
Conger mine eventually became the greatest tungsten mine in the world.
During World War I, Nederland's population swelled to 3,000--twice the
size it is today--and another 2,000 were estimated to live nearby. In
each boom, men came to mine, open stores, and transport goods and ore.
They brought families with them, and many towns sprang up, including
Caribou, Eldora, Lakewood, Tungsten, and Rollinsville. Some of these
communities have survived, while others remain only in memories and
photographs.
