This is one of the most complete and accurate property-ownership maps we have. They are especially interesting for the I.A. notation, meaning “Indian Allotment,” on several of the parcels on Prosper Ridge. I got the map sections from the Department of Natural Resources in Eureka, on two different occasions. The first set (downriver near Petrolia) i had copied years ago. Over the years i realized i should have the whole watershed on hand, so i went back… but this time i took photos of the map. These are the more blue-toned pictures. Anyway, a big thank-you to the DNR and its caretakers (in this recent case, Andrew Bundschuh) for keeping these maps on-hand, organized, and available to serious researchers.
As always, for explanations as to how to use the maps (if you have the description of a piece of property and are looking for it, for instance), go to this earlier post.
Note: This map is so big, i am splitting it into three sections… the lower Mattole Valley, and its coast; upriver (Upper Mattole to the Briceland area), and the “Lost Coast.” All sequences will travel north to south.
