Yep, this is the main appearance of settlements in Arizona and Dinetah. Many of the old ones are revered as holy sites and home to powerful temple complexes.
In a recent timeline of mine, I speculated how the native cultures of the Southwest could have utilized crossbows for defence of their towns and dwellings, after Native Americans discovered simple crossbows centuries before that and the idea eventually reached the Southwest.
The Navajo were also noted to have historically built the pueblito forts in a remarkably European-like castle style (quite different from typical earlier pueblos, with their mostly adobe covers on the outside) and to like hunting with bows on horseback, after they adopted horses on a larger scale.
One has to wonder whether the Southwesterners of the Medieval America future world have figured out crossbows could be very practical for defending Oasisamerica pueblito-style forts and pueblo-style fortified towns. And even for hunting on horseback and on foot, besides regular bows. Unlike in my timeline, there aren't that many technological and material and knowledgebase restrictions.
