In Indiana Jones, are faintly-drawn areas of the map all the time accessible one way or the other?

Hello of us hopefully that is alright to publish right here. I’m taking part in Indiana Jones and I’ve seen these two faintly drawn in areas on the very farright hand facet of my map. I can’t for the lifetime of me determine it out if I’m meant to have the ability to get to them and the way. Can anyone affirm for certain that these areas are accessible?
