Find location from Red Dead Redemption Trailer

[Jofefe]

Hello everybody,

Recently I was watching old RDR2 trailers... you know, just for enjoying them again and I saw this location on 00:12: 

 I have been trying to find it but I have not been able to do it. Does anyone know the exact location and could help me to find it?

Many thanks in advance

Looks like the Big Valley which is North of Strawberry.  The Little Creek River runs through it.  That's where I have done a lot of hunting.

I recognize that body of water. It's just south of Hanging Dog Ranch.

Thank you both! I'll check it later
