Roop's Fort

Susanville, Lassen County · California
Erected by Grand Lodge F.&A.M. of California, 1961

The war fought at this log house was over a tax bill. Honey Lake Valley's settlers believed they lived east of California, founded their own Territory of Nataqua here in 1856 to keep clear of its tax collectors, and later joined Nevada as Roop County. When the Plumas County sheriff came to collect in February 1863, Isaac Roop and about thirty men held the building, called Fort Defiance, through four hours of firing; two defenders were slightly wounded. A joint survey settled it the next year: Susanville was in California all along.
