The printed Trinity County plat book and the online parcel map answer the same question, who owns the land near Coffee Creek, in different ways. This guide covers finding a printed edition for Trinity County, California, and using the free parcel map in the meantime.
Plat books vs. recorded plats in Trinity County
Private publishers compile plat books from county records, so a county edition is a snapshot of who owned land near Coffee Creek the year it was printed. Deeds and recorded plats, not the atlas, still govern land near Douglas City in the county.
Finding the tract on the Trinity County map

Finding a printed Trinity County plat book
Private publishers have printed plat books for many rural counties, but editions for Trinity County come and go; inquire at the courthouse, the extension office or a farm supply store in Coffee Creek. An old atlas can help trace when a tract close to Burnt Ranch split off from a larger farm.

Small parcels and town lots in Burnt Ranch are often too small to label on an atlas page, which is another reason the online map is better for them. Genealogists in California often pair an old Trinity County atlas with deed records to follow a farm through the generations.
