Chapter 5 help

This is my first playthrough. Camp just moved to the Murfree cave. Do you lose access to fast travel and camp supplies after Shady Belle? Bummer. Ever since Guarma, the story feels like it's ramped up and I'm not exploring as much because everything seems a bit urgent. Can I relax a bit or is there still a lot of game to go? My save is at like 68% or something.

I haven't come close to finishing the dino bones, unlocking all the suits, or finding the rock carvings. Otherwise, it feels like side content and random encounters are starting to dry up. Just not sure if this is the point where I steam ahead and finish the story or not.

edit: looks like fast travel map is back now.
