Alder Gulch (alternatively called Alder Creek) is a place in the U.S. state of Montana, where gold was discovered in May 26, 1863 by William Fairweather and a group of men, including Barney Hughes, Thomas Cover, Henry Rodgers, Henry Edgar and Bill Sweeney who were returning to the gold fields of Bannack. Unable to keep quiet, the first stampede of miners reached there June 6, 1863 and the population swelled to over 10,000 in less than 3 months. The "Fourteen Mile City" ran the length of the gulch, and included the towns of Virginia City, Summit, Alder, Nevada City, and Adobetown. The people lived in brush wickyups, dugouts and under overhanging rocks. The largest of these temporary towns that sprang up nearby was named Virginia City. Later named the territorial capital, Virginia City lost the hold on the title of State Capital to the newest, richer vein, at Last Chance Gulch (Helena), the current capital. The diggings were the richest gold placer deposits ever discovered, and in three years $30,000,000 was taken from them, with $10,000,000 taken out in the first year. Alder Gulch was named for the alder bushes that grew along the creek. Wiki.
