Canvas looks like Navajo? 36x24 on canvas might be some kind of oil, signed but can't decipher. Any info would be appreciate

I don't remember where I got this. Any help with the identification will help future generations. I'm certain it is Native American, but from where? It reminds me of Navajo weavings, it is just canvas with some type of paint. It is very precise, and I can't read the artist signature.
