Humbug Valley is located a bit south and west of Lake Almanor. It is an interesting locale, and worth the trip if you have never been there.
In 1855, B.K. Ervine and William B. Long used the valley for stock-range. Two years later, gold was discovered and set off a flurry of mining operations. Long and his father-in-law, Allen Wood, built a hotel there, and a sawmill mill, too, and thus the town of Longville came into existence. In 1862, Long came to Susanville and purchased William Weatherlow’s ranch, known today as Susanville Ranch Park.
Longville continued to flourish, and then came along World War I and everything changed. Like so many places Longville would slowly become de-populated and residents never returned after the War. The Longville Post Office that had been in operation since 1861, closed in 1918.
