Bonanza has an elevation of only 9,478 feet, but we will allow the 22-foot difference as only 16 people live there nowadays and their math may be rusty. This is down from 1,500 when the silver stream was flowing. Historians estimate prospector numbers by saloons and dance halls. Bonanza had 43 in its heyday. At an average 35 patrons each they must have been making whoopee.
