There is one good candidate for the location of a dwelling at Hinojosa: the
small pit hearth known as Feature 5, which was surrounded by a small area relatively free of debris. This interactive graphic allows you select one of the layers on the left to see the distributions of different kinds of evidence. The red circle marks the possible location of a dwelling (hut). Lacking any direct trace of postholes or other definitive structural evidence, we cannot be sure.
Nonetheless, based on the accounts of early Spanish travelers, it is almost certain that structures would have been erected and present at the Hinojosa camp during any stay beyond a brief visit.
