The Long Valley Lumber Company was a perfect example how the lumber industry locally evolved. Instead of meeting local demands, which it did, the production was focused on outside markets.
The company established in 1906, was also known by its owners name Doyle & Crowder. They located their mill in a location known as Cannon Field, near the top of Doyle Grade. On a side note, local folklore had it that the name of Cannon Field was attributed to where John C. Fremont in his 1844 expedition discarded cannon balls, and would eventually at some unknown location abandon a howitzer. In all actuality, it was so named after William Cannon who lived there during the 1870s.
Anyhow, back to the topic at hand. The mill owed its existence to the Western Pacific Railway to supply ties for the construction of that railroad. Once the railroad no longer needed ties, the mill closed in 1910. In December 1917 the mill was sold to the Lassen Lumber & Box Company. That company moved the mill to Susanville, where it was used cut the lumber and timbers for a much larger mill there.
An interesting tidbit. At an Easter picnic in 1946 at the old millsite, Betty Richens found a 1906 $10 gold piece in the old sawdust pile.
