As the bunker was situated beneath Polis, the people occuring when Bekka Pramheda landed with hazmat suits most likely were members of the Second Dawn. As mentioned in season four, there was definitely a reason to why "From the ashes we will rise." became a sort of grounder prayor, as the Mountain Men didn't really have any specific sort of relation with them, it would be highly unlikely that they transitioned the motto. Also, as you said that we haven't heard of any other grounder location than the east coast, we actually have. The first episode of fourth season showed two people walking in a desert, in Egypt, as pyramids were seen, unless they would have been built in the United States' east coast sometime between the years of 2014-2052.
