For decades, archaeologists have known that wetlands are exceptional sources of food, medicine, water and other resources necessary to surviving in nature (Nicholas 1991 etc.).  Many peer-reviewed articles from fieldwork in the north-east of North America have illustrated that the abundance of archaeological sites around wetlands are second to none.  Often considered to be the grocery store of the prehistoric period, wetlands provide virtually everything required for survival on the changing landscape.  Wetlands are currently not considered as a source for archaeological resources in New Brunswick.  While no records are available for wetland loss in NB, in parts of Ontario, ~80% of wetlands have been lost, and the United States suggests as much as 50% loss since European arrival.

     The first people to inhabit the region (more than 10, 000 years ago) were highly mobile hunter‐gatherers who were very proficient and well adapted to the existing tundra environment.  Through the identification of lithic material chosen for their stone tools, it is clear that they had a wide-ranging area of resource procurement and habitation.  It is not uncommon to find lithic material on Palaeoindian sites that originated many hundreds of kilometres away.  Due to the rapidly changing environment and low capacity for resources on the tundra, travel was a necessity to follow migrating caribou and other game along with newly established plant resources and using wetlands as more stable areas of resource procurement.  Thousands of diagnostic Palaeoindian artifacts have been recorded throughout north-eastern North America.  Many of these well‐studied Palaeoindian sites are associated with either wetlands or former lakes/ponds, for example, such sites as the Wapanucket 8 site in Middleborough, Mass., Bull Brook in Ipswich, Mass., the Shoop site in Harrisburg, Penn. and the Red Wing site in Ontario.  The location of late Pleistocene/early Holocene archaeological sites are frequently associated with wetlands for many reasons including access to food resources and fresh water.  In a landscape of continual climactic change, wetlands were a source of stability that attracted game of all forms and were some of the first areas to be colonised by plants for use as tools, foods and medicinal purposes.  In a Maine Archaeological Society Study Unit on Palaeoindian sites, the Maine State Archaeologist Arthur Spiess writes “Most of these sites are located in sandy soils in proximity to some sort of stream or wetland” (Wilson and Spiess 1990, pg. 20).

Palaeoindian artifacts, throughout the north‐east, are widely distributed but controlled by the presence of rivers, lakes and wetlands (National Park Service, 2006).  “In the course of sequential settlement moves emphasizing locations optimal for acquiring foods (wetlands and river terraces)…” (ibid.). Describing a Late Palaeoindian site that overlooks the swampy headwaters of a small drainage in south‐western Maine, the author wrote “Perhaps it was the swamp that attracted people to this location, analogous to a postulated Early Holocene wetlands‐oriented settlement pattern postulated for southern New England” (Bourque 1992).

     As the cultural sequence progresses, more work has been done to research palaeoenvironments, which helps to identify how and where people lived in the past.  Palaeoenvironmental reconstructions have been conducted in Maine and other locations that illustrate changes throughout the Holocene, some from open lakes to marshes (Funk 1992, Nicholas 1988, Sanger & Newsom 2000, Swayze 2006).  “The intermediate stage, the marshes, would have been the most productive areas from a human subsistence viewpoint, as they would have provided fish, fowl, aquatic mammals, and edible plants” (ibid. pg 14).  Throughout the middle Holocene (approx. 7,000‐3,000 years ago) “The Middle Archaic‐Late Archaic continuity model builds on another, the so‐called ‘two population model’ (Sanger 1996b), which posits a cultural adaptation to interior Maine and its wetland environments that was distinct from a coastal cultural adaptation for much of the pre‐European period (see also Robinson l996a).  We know that key resource procurement areas, such as wetlands, changed through time from lakes, to marshes, to peatlands (Almquist‐Jacobson and Sanger 1999), while significant upland vegetation species underwent variability in terms of species mix (Almquist‐Jacobson and Sanger 1995)” (ibid. pg. 18).

“Middle and Late Archaic sites in central Maine tend to be found in close proximity to wetlands. Is this an artifact of our still relatively small sample?  Or are we detecting a pattern of settlement related to exploitation of wetlands, similar to that espoused by Nicholas (1991, 1998) for southern New England?  Could it also be that changes in the environment over time have either masked or affected the archaeological record in some way, such that only those sites close to wetlands have survived?  We suspect the association is culturally significant; that is, people found it desirable to be in close proximity to wetlands” (Sanger & Newsom pg 13).

     The Robbins Swamp research conducted by Nicholas (1992b), indicates that during the early Holocene, wetland mosaics were a major component of the landscape and provided a stable, reliable and productive source for food/water, plant and animal resources, as well as ideal locations for habitation.  Incredibly, Nicholas goes on to report that of the 37 early Holocene sites recorded around Robbins Swamp, 38% are located on river and stream terraces, 32% on wetland margins, 8% on wetland margins/river terraces and 22% on former lake terraces above wetlands!  A further 128 Middle and Late Archaic sites are also recorded around Robbins Swamp.  With a strong focus by aboriginal groups on wetlands in the first five or six millennia post-glaciation, to ignore them, leaves a massive hole in our understanding of the early populations of the region.  To ignore wetlands, not only as a focal point but also as a source of archaeologically relevant data, one extinguishes virtually all hope of recovering any organic artifacts or ecofacts that may tell us far more information than is normally collected from a typical New Brunswick archaeological site.

     With the number of wetland-associated archaeological sites considered as abundant as the confluence of streams (highest magnitude), it is also no wonder that they are focal points of significant ceremonial sites.  Many important burial/cemetery sites in the New Brunswick are associated with wetlands (Jemseg Crossing, Cow Point red ochre cemetery, Augustine Mound), not to mention the large volume of important habitation sites.  We know from detailed analyses of faunal assemblages from archaeological sites in Maine (Almquist-Jacobson & Sanger 1999), that wetland plant and animal species were an important part of the Native diet and also of their spirituality (the Wolastoqiyik and Mi’kmaq story of Glooscap, which includes mentions of beaver, moose, turtle, bulrush etc.).

The scarcity of resources from the Palaeoindian period to the Historic period meant that the presence of relatively stable hydrological environments were attractors to both game and plant species and thus a very desirable location for people searching for food and water.  This stability in resources also encouraged extended periods of habitation and a return to a specific location, leading to the formation of formal cemeteries.  Therefore, we must first determine whether there are any heritage resources present in and around these wetlands before they can be allowed to be destroyed.

One of the big mysteries for people outside of archaeology is how we are able to locate archaeological sites that have not already been exposed in some manner.  There are many key attributes that we look for when considering what makes a good place to live and therefore create a site in the past.  Most of these attributes are the same things that draw people to specific locations today.

Identifying landscape development to understand areas suitable for habitation.

Identifying landscape development to understand areas suitable for habitation.

Some of the characteristics for a good place to live are access to potable water, food (plant or animal), suitable terrain (flat, level, well-drained) and ease of access.  Generally, in the warm weather months, this means a nice floodplain or lake side locale.  Often, the trick can be identifying these locations as they were in the past.

Locating landforms that were once at water’s edge but now deep in a forest.

Locating landforms that were once at water’s edge but now deep in a forest.

As we know, streams often meander, meaning that where the watercourse is today may not be where it was in the past.  And lake/marine levels raise and lower depending on many factors (melting glaciers, subsidence, spring flood etc.).  Being able to identify old, stranded beaches or other key landforms in the middle of a forest, far away from any current watercourse is in part, what professional field archaeologists work towards locating.

Usually, the quickest and easiest methods for identifying these key landforms is by studying topographical/geological maps or modern and historical aerial photographs.  With an experienced eye, interpreting the landscape and looking for relic beaches or other areas of archaeological interest is the first step in finding sites.

Using geophysics to quickly and efficiently map buried sites.

Using geophysics to quickly and efficiently map buried sites.

Once a site is found, non-destructive techniques may be used to quickly map the limits of the site (reducing the amount of excavation) and to identify areas of interest (hearths, foundations, pits, intense use).  Engaging an experienced and qualified archaeological geophysicist that will use methods like magnetometry, resistivity and ground penetrating radar; much more information can be extracted from a site than conventional excavation alone and can help to reduce the cost associated with a lengthy stay in the field.As always, follow-up excavation is required in order to ground truth the geophysical results.

Depending on the needs of the client or the research, varying amounts of additional excavation may occur in order to completely remove the site (and as much information as possible) before development or to identify key pieces of information (age, function, size).  There are also numerous in-field techniques utilising advanced technology and other disciplines that may add much more information to whole picture of what went on at the site in the past.

 A chert source in northern Maine

      A few years ago, I decided to take in the Maine Archaeological Society’s annual conference that took place at the University of Maine at Presque Isle.  As a long time researcher of the Palaeoindian period in the Canadian Maritimes and the broader north-east of North America, this conference caught my attention.  In particular, Dr. Arthur Spiess’ (Maine Historic Preservation Commission, State Prehistoric Archaeologist)presentation on the early post-glacial period of northern Maine.  Dr. Spiess keynote address tied in many of the known and some new sites in the northern part of Maine and adjacent New Brunswick/region.
