A popular hiking trail in Rocky Mountain National Park leads to the site of the historic mining town of Lulu City.  When precious metals were discovered there in 1879, as many as 500 prospectors showed up.  When the mines played out four years later, they departed in haste for other promising boom towns.

Lulu City was named for the daughter of Benjamin Franklin Burnett, one of the town founders. At its height, the town had a hotel, post office, and a justice of the peace.  It was served three times a week by a state coach from Fort Collins, on the other side of the Continental Divide.

There were probably ten saloons which drew customers from various mines in the area, such as the Rustic, Friday Nite, Tiger, Carbonate and Southern Cross.  These yielded low grade gold, silver and lead but the remote location of the Lulu made the cost to process the metals so high that efforts were soon abandoned.  The closest smelters were probably well over 100 wagon miles away.  Read more here http://www.grandcountyhistory.com/Places/Towns/LuluCity/tabid/204/Default.aspx
