soft vintage camp blanket, Chief Joseph pattern Indian blanket Pendleton wool?

Unmarked vintage camp blanket - no label at all that we could find, though this looks like a Chief Joseph Pendleton blanket to us. It measures 104" x 94".

It's soft, not scratchy - nice wool, or maybe a wool acrylic? We think the blanket binding is not wool at all, but aren't familiar with the newer Pendletons, maybe they're not using wool felt bindings any more?

It's a newer piece, 25 years or less at our best guess. It's used, and has some soil, and several big holes and snags at the edges from a bed frame or bunk. Not perfect, but soft and cozy with years of life left in it yet.
