We present a synthesis of treatment of the dead from before 700 b.c. to the fifteenth century a.d. in the lower Ulúa River Valley of northern Honduras. Building on evidence of burial alignments to a prominent mountain first identified for the Classic period, we argue that mortuary rituals served to integrate politically independent communities within a shared cosmological landscape. We identify alignment of burials toward the same mountain beginning in the Middle Formative period. At this time, a cycle of mortuary treatment resulted in bodies of some of the dead being commingled in shared secondary burial sites in caves, significant locations in the cosmological landscape. During the Classic period, secondary mortuary treatment continued, now performed within settlements again united by orientation to a shared cosmological landscape. The addition of solar alignments may be evidence of adoption by some families of Lowland Maya cosmological beliefs. This impression is solidified in Postclassic burial practices that align closely with those of specific Lowland Maya societies. We argue that the afterlife cycles through which the living interacted with the dead, in a tension between individualization and communal belonging, included strategies through which social relations, community histories, and ties among communities were created.

Repatriation of human remains and associated funerary objects under NAGPRA and the increased use of culturally informed curation practices for sacred, religious, and ceremonial objects are important steps toward restoring control over cultural patrimony to Native Nations in the United States. Many museums holding Indigenous belongings have begun a collaborative care approach involving Indigenous community voices and improving access to collections. However, this framework has not been applied to many animal remains curated in American archaeology museums, which remain broadly beyond the care or administrative purview of Native people. Because many Indigenous worldviews do not hold a clear separation between the human and animal spheres, common practices applied to animal remains are not congruent with the idea of respectful or culturally informed care. Here we outline steps to shift the treatment of animals through the application of Indigenous knowledge to museum collections.

People experience heritage at historic sites as landscapes that include both environmental and cultural meaning. Heritage as social action overcomes the dichotomies of nature versus culture and past versus present, which are obstacles to resiliency and sustainability in this era of rising sea levels. That insight is exemplified by a program addressing climate change on the Florida Gulf Coast. The program includes community conversations on climate change and initial steps at multiscalar research using techniques from archaeology, environmental studies, and biology. At the broadest scales, the approach reconstructs the distribution of coastal heritage locations from the decades preceding human-caused sea-level rise to the present. At finer levels of temporal and spatial resolution, research documents vegetation, marine invertebrates, and material changes. At the finest scales, studies of microorganisms that inhabit historic and archaeological sites are inventoried. Integrating those scales through community-based archaeology offers the social meanings for coastal heritage under threat of rising sea levels, both to motivate actions to preserve the past and to prepare the public for the coming landscape transformations as an avenue for community conversations.

The articles compiled here offer examples of how the impacts of anthropogenic climate change in coastal settings are monitored and measured, how the broader public can be involved in these efforts, and how planning for mitigation can come about. The case studies are drawn from the southeastern United States and the British Isles, and they indicate the great potential that cooperating communities of practice can offer for addressing climate-change impacts on cultural heritage.

At coastal archaeological sites, measuring erosion rates and assessing artifact loss are vital to understanding the timescale(s) and spatial magnitude of past and future site loss. We describe a straightforward low-tech methodology for documenting shoreline erosion developed by professionals and volunteers over seven years at Calusa Island Midden (8LL45), one of the few remaining sites with an Archaic component in the Pine Island Sound region of coastal Southwest Florida. We outline the evolution of the methodology since its launch in 2016 and describe issues encountered and solutions implemented. We also describe the use of the data to guide archaeological research and document the impacts of major storms at the site. The response to Hurricane Ian in 2022 is one example of how simply collected data can inform site management. This methodology can be implemented easily at other coastal sites at low cost and in collaboration with communities, volunteers, and heritage site managers.
