How far north did conquistadors end up going to? I know that Alta California ended up having a border pretty far to the north, but no resource I can find on the conquistadors shows that they even went as far as the thirtieth parallel.
For prospective working ideas, I want to know: How far north did the latest, furthest conquistadors go? And who went there?
Thanks in advance.
EDIT: more research led me to Juan De Fuca. Please disregard.
