Initialization is different for each of the various types of rollovers.
These are the most common types of rollovers. Nestled four miles west of Nederland, Eldora started out named Happy Valley in 1896. Known as a town of 'serious miners', Eldora was unique in its early years for what it did not have - sinful dance houses, according to the Denver Republican newspaper in 1898. In mid 1898, Eldora was reported to include over 1500 residents and 300 buildings. The town was renamed El Dorado when a rich strike of sulfide ore was found.
