2Full Spectrum Archaeology (FSA) is an aspiration stemming from the convergence of archaeology's fundamental principles with international heritage policies and community preferences. FSA encompasses study and stewardship of the full range of heritage resources in accord with the full range of associated values and through the application of treatments selected from the full range of appropriate options. Late modern states, including British Columbia, Canada, nominally embrace de jure heritage policies consonant with international standards yet also resist de facto heritage management practice grounded in professional ethics and local values and preferences. In response, inheritor communities and their allies in archaeology are demonstrating the benefits of FSA and reclaiming control over cultural heritage. Archaeology and heritage management driven by altruistic articulation of communal, educational, scientific and other values further expose shortcomings and vulnerabilities of late modern states as well as public goods in and from FSA.Archaeological resource management; Cultural heritage management; History of archaeology; International heritage policies 3 Archaeologists in the later-2010s face some big questions. Is cultural heritage best treated as a part of archaeology, or vice versa? Can (and should) archaeology hold together as a unified discipline in the face of ongoing growth and diversification, especially in heritage resource management (HRM) archaeology and other fee-for-service practice? Should we proceed in riveting our disciplinary focus upon places and objects having scientific and historical values? Or, are the interests of archaeology and our diverse clientele better served by and through what we refer to, following Welch and Ferris (2014:97), as full spectrum archaeology (FSA)-an aspiration to employ an archaeological lens and other means to understand all cultural heritage, to attend to all values associated with heritage, and to consider management and treatment options that reflect and embrace those diverse values? Will we, archaeologists, continue the comfortably institutionalized ostensibly objective study and management of sites and artifacts within internal disciplinary logics and agendas, or shall we respond to international policies and increasingly vocal inheritor community preferences by expanding and diversifying archaeology into an essential if not always sufficient means for helping to identify, assess, and treat broad arrays of particularly significant cultural heritage? These seemingly academic questions go to the heart of practical and political relations between archaeology and late modern states, especially as regards to engagements archaeology and archaeologists are pursuing with international, national, regional, and communal partners to make decisions about what heritage will be carried forward and may help shape the future.In dialogue with the other essays in this collection, we seek to set a course for archaeology that stems the rising tides of late modern state control...
