The Red Paint People, Doggerland and my DNA.

Over the last couple of months I have been putting up the occasional post on my own family tree, as it is becoming defined by DNA analysis, and at the same time have been looking at some of the early arrivals of Indians in Maine and the North East American continent. (My interest in the latter was initiated by the question of when Europeans first arrived on the continent in enough numbers to influence facial features of the locals).

Two weeks ago I was fortunate to be able to attend a lecture by Bruce Bourque, the Curator of Archaeology at Maine State Museum, and the authority on the Red Paint People, of whom I have written earlier with a follow-up post on their travels. His talk, and the book he just recently released (The Swordfish Hunters) provides much more detail on a people that have largely been neglected by “the archaeologists of Harvard,” who have tended to disregard significant developments this far north of Boston.

The Red Paint People are also called “the Moorehead Phase”, after Warren Moorehead, who first identified them as the “Red Paint” people, because of their custom of burying red ocher with the bodies in their cemeteries. They flourished in a small part of Maine, and their cemeteries have been found along the banks of local rivers. There is, however considerable evidence that they harvested fish and sea-food (their cemeteries have been found in large shell middens), with a peculiarity that they also hunted, ate and used the bones and rostra (the “sword”) of local swordfish. The latter, in particular, was used to provide a stiffened mount behind the harpoon and spear tips used in hunting. They appear to be the first to hunt swordfish, which would have been a dangerous prey for early Holocene man, since they have a nasty habit of attacking the boats of those who have just stabbed them with a harpoon.

The book is a fascinating story of detective work, and archaeology as it builds a picture of a people that began around 5,000 years ago and suddenly disappeared around 3,800 years ago. Dr. Bourque points to evidence that it does not fit within an overall unified culture which has been described as the Maritime Archaic, but rather stands on its own, and emerges from the “Small Stemmed Point” tradition that preceded it. But is totally separate from the Ceramic period that follows.

One of the intriguing parts of the story lies in the thousand-mile link with the Ramah Peninsula in Labrador, that I discussed in a previous post, and Dr. Bourque also points to close similarities between the findings in Maine, and those at the Port au Choix site. One identifying characteristic lies in the development of stone gouges, for use in hollowing out the inside of dugout canoes.


Figure 2. A Stone Gouge from Maine, and an artist’s rendition of how it would be hafted. (The Swordfish Hunters).

The gouges, as the book argues, show that the Red Paint Peoples were building substantial canoes and boats around 4,000 years ago, that were substantial enough for voyages of a thousand miles, and that this would also make them viable for use in harpooning swordfish (an art in itself as the book illustrates).

The climate change around the time that this culture was flourishing in Maine is not seriously discussed in the book, but I think that it is worth looking at, in context, because it ties in a little with what was happening across the Atlantic, where the culture that built Stonehenge had moved into Britain.


Figure 3. Climate swings in the Northern Hemisphere over the past 10,000 years (the Holocene) (Consulting Geologist)

The significance of these temperature variations is often significantly discounted as climate scientists today would rather emphasize the point of the effects imposed by man, rather than the natural effects we cannot control. Yet the higher temperatures that did exist, even as recently as the last (Medieval) Warming Period are evidenced, for example, by the recent uncovering of an Eskimo village which has been buried under a glacier for the past 500 years. The inhabiting tribe of Yup’ik Eskimo lived, among other things, on caribou and lived at Quinhagak in Alaska. Without the protective ice cap that has covered the site from the time that the Yup’ik left there at the beginning of the Little Ice Age, the site is now rapidly being eroded into the Bering Sea (a fate that is similarly threatening the sites in Maine, where coastal erosion and sea level changes have covered most of the Red Paint People’s locations). But it indicates that we are only now reaching the temperatures at that site that prevailed in the Medieval Warming Period.

The Red Paint People lived at the beginning of what is now referred to as the Minoan Warming Period. And, from data obtained from the Greenland Ice Cores, it is possible to note a couple of facts about the time that the tribe appears to have vanished. First, if the temperatures, as derived from the Ice cores recovered from Greenland are examined in a little more detail:


Figure 4. Temperatures in the region over the last 5,000 years (from the Greenland GISP2 Ice core)

Perhaps more to the point, if the extent of sea ice at the time is considered (from the same source) it fell to an historic low during the Minoan.


Figure 5. Sea Ice extent over the Holocene (The Ice Chronicles ) (Note the plot has been flipped, relative to the original, in order to conform to the consistency of showing the older period to the left of the plot in the rest of the post).

With this considerable warming the ice retreated from the shores of Greenland, and it became an even more hospitable place that it was at the time almost 3,000 years later when Erik the Red came calling. This warming had another consequence, because it led to a steady rise in the levels of the sea. This is shown in the book as it affects Maine, important since it shows how the shoreline dwellings from the period have since been inundated.


Figure 6. Sea levels off the coast of Maine over the Holocene (The Swordfish Hunters)

But in Europe that sea rise from the beginning of the Holocene had another consequence. It flooded the land-bridge (known as Doggerland) between what became the isle of Britain and the continent.

Within the British Isles, by 4,000 BP the country had been colonized for about a thousand years by the arrival of an agricultural movement that displaced the earlier hunter-gatherers and, in turn. rapidly changed from a “slash and burn” land clearance into the development of a “celtic arrangement of fields. Colin Burgess in "The Age of Stonehenge" has noted that the settlements towards the end of that transition were already being constructed defensively.
A more recent unmarked burial pit at Fengate contained three disarticulated burials and one, crouched, the latter with a leaf-shaped arrowhead still sticking between the eighth and ninth ribs.
The warmer clime was conducive to the spread of agriculture and an increasing density of population. The cutting of the land bridge, and the slow flooding of what later became the Dogger Bank, in the North Sea, had a personal consequence.


Figure 7. The location of Doggerland about 7000 BP (Bryony Coles via doggerland)

My Y-chromosome has been designated as R1b1b2a1a1d*, which is a variety of Celt, that, as I have mentioned in an earlier post, had come down from Cro-Magnon man. The analysis that has evolved over the past few years (apparently starting at 23andme suggests that this a “Freisian” variety of Celt and there is a body of thought moving to the conclusion that they were the inhabitants of Doggerland that were driven to Britain when the final inundation occurred around 5500 years ago, just before the first circles at Stonehenge were constructed. (And here I now discover that maybe I wasn’t the first of my lineage to work on a Stonehenge).

The first circles at Stonehenge were developed about 5,000 years ago (at the left side of Figure 4). But around 2150 BC or some 4000 BP the Beaker People arrived. In contrast with those, maybe us, who had first developed the site and were moon worshipers, they worshiped the sun. What made the Stonehenge site become what it did was that the simple markers already there to align critical lunar phases could, by moving around the circle ninety degrees, also align to the major solar alignments at mid-winter, mid-summer etc. The ruling elites of the time became more powerful, and with the warmer climes helping sustain agricultural production, society became more static. And the more powerful had enough manpower available to develop, over the next millennium or so, the full glory that became Stonehenge. They also grew into the Wessex Culture with its elaborate and rich graves.

The Beaker People were Celts and still, at the beginning of this time, used stone axes and flint-shaped arrowheads. But copper daggers are found even in the earliest graves and this was the time where the culture was moving into the Bronze Age in Britain, some time after it had developed elsewhere in Europe.

Given that the Red Paint People were aware of native copper deposits, (and were starting to make small ornaments with them) had they known of the metal forming traditions developing in Europe then metal objects would have shown up in the graves. They did not, and even to the time of Champlain stone tools were in use.

So it is logical to conclude that seafaring though the cultures were on both sides of the Atlantic they did not communicate at this time, at least not well enough to teach metal craft, at a time when it might have been easier to travel, from one side of the Atlantic to the other. On the other hand, it might be possible to conjecture an explanation for the long and narrow bayonet points which Dr. Bourque points out as a significant feature of Red Paint burials. He notes that these are too weak to have any great utilitarian value in society, because they were made of stone. He therefore suggests that they had only a ceremonial aspect that has been lost. But it could be that they were an attempt to copy the spear heads that were beginning to be developed in Britain at the time, but which were made utilitarian only by being made of metal. And that would suggest some form of communication between the two societies.

There remain a couple of additional thoughts, both about the ability of early societies such as these to travel long distances, and the mysterious disappearance of whole societal segments. But they arise in events in Greenland that happened during the Medieval Warming Period; the migration of the Thule from Alaska to Northern Greenland in 1000 AD, and the abandonment of the Western Settlement of the Viking in Greenland. Since this is a different time period I will therefore leave those topics to a subsequent post.

OGPSS - Pipelines and Eastern Canada

I wrote, last time, about the projected pipelines that are being anticipated to take advantage of increased production from the oil sands in Alberta, Canada with the intent that I would use that to lead into a review of the oil sands operation itself. However Gail has raised the issue of the proposed reversal of the pipeline (Line 9) that runs from Sarnia in Ontario to Montreal so that oil would flow to the Suncor refinery in Montreal, rather than the current flow which runs the other way. (Sarnia is right by Detroit). The pipeline reversal is planned to continue beyond Montreal, to include reversing the flow of a supply pipeline from Portland, ME so that the oil from Alberta might also supply northern New England. The project has been called “The Trailbreaker” and had been postponed two years ago when demand declined.

The overall question of the relative role of exports and imports on the Canadian oil supply equation was also raised in comments on the previous post. As a result I am going to look a bit more into the overall Canadian picture, and particularly that in the East Coast, and will postpone the oil sand piece a week (sorry Neil). To begin it helps to look at the current projects that Enbridge have in mind for pipelines.

Overview of the Enbridge planned pipeline projects (Enbridge)

The Ozark pipeline, which is shown running from Cushing to Wood River was closed on Friday, Sept 30th, when the pipeline was found to be exposed as it ran across the bottom of the Mississippi River. It carries around 240 kbd and the shut down is precautionary, since there has been no leak detected.

The dark green arrow from Cushing to Houston will be known as the Wrangler pipeline and would carry up to 800 kbd from Cushing to the refineries along the Gulf, competing with the Keystone XL, which is planned to bring an additional 500 kbd down from Alberta (about 500 kbd flows through existing connections). The intent is to move the oil away from Cushing where it is proving to be a bit of a glut.

With this surplus, and the ability to move oil around the Mid-West, the need for additional feed down from Montreal dissipates, and thus the argument for the reversal of flow so that crude from Alberta can be sent back up that pipe to the refineries in Eastern Canada. At present oil comes by tanker to Portland, ME and then enters the Portland-Montreal Pipe Line (PMPL) system. The oil flows through either an 18-inch or 24-inch line up to Montreal, a distance of 236 miles, with flow then continuing to Sarnia. A certain increase in energy security would thus be achieved for the East Coast of North America, if the oil refined on the East Coast was produced in North America, instead of coming from Russia and the Middle East. At present flow would be reversed in only one of the pipes, the 18-inch, coming from Portland. At present some 200 tankers a year offload in Portland, and send around 95 kbd up to Montreal. (The pipeline came into being in 1941 to avoid exposing oil tankers moving into Quebec to U-boats).

Portland Montreal Pipe Line (Wikipedia)

If one looks at the overall flows of oil in Canada, the increasing reliance on Albertan oil can be appreciated.

Flows of Canadian crude oil in thousand cubic meters/day – (multiply by 6.3 to get kbd) in 2009 (Canadian NEB)

Canadians consume around 1.5 mbd, of which half is gasoline, and 30% diesel. I discussed their exports in the last post.

Interestingly the largest exporter of gasoline from Canada to the US lies further East, where it comes from the Irving Oil refinery in St John New Brunswick with the 300 kbd refinery shipping 75% of the gasoline it produces into the Eastern United States.

There are two other refineries in the region, the Dartmouth refinery at Halifax in Nova Scotia refines 82,000 bd of crude, largely for the Eastern provinces of Canada. The crude is off-loaded from tankers, refined and then loaded onto smaller coastal tankers for delivery.

Yet further East is the Come by Chance refinery, now the North Atlantic Refinery in Newfoundland. In its time it was one of the largest bankruptcies in Canadian history, but it now refines some 115 kbd that arrives in 320,000 ton tankers at the nearby ice-free port. It suffers from that bankruptcy in that a subsequent sale was commensurate on the product not being sold in Canada (outside of Labrador and Newfoundland), which means that the products largely ship to the United States.

Yet one must go even further East to find the oil fields of the Eastern Canada Sedimentary Basin. And unfortunately while the nearest refinery might be near an ice-free port, the fields themselves are not.

Eastern Canadian Sedimentary basins and hydrocarbon fields (Center for Energy )

The fields include White Rose which is expected to yield around 230 milllion barrels, at around 120 kbd, with a life of 12 – 15 years. First oil was in 2005.

Terra Nova is estimated at 406 million barrels. With a production of around 125 kbd it is anticipated to last 18 years. Production began in 2002.

Seasonal floating ice in these parts varies from 1.6 to 5 ft thick and an average wind speed of around 20 mph. also leads to ice buildup on the tankers and superstructure making it a consideration in operations, as are icebergs. (Remember the picture of the tug pulling an iceberg). That was taken around here.

Hibernia is also producing at around 126 kbd, and by August 2010 had produced 704 million of the 1.4 billion potentially recoverable oil from the field, Approval has now been given to extend development to the south.

Current plans to develop Hebron, some 6 miles N of Terra Nova include also the fields of West Ben Nevis, and Ben Nevis. Production is expected to begin in 2017, at a rate of around 150 – 180 kbd of oil and 200 – 350 kbd of water. Reserves are considered to be in the 400 – 700 mb range.

Although these numbers are significant, and will provide for a considerable fraction of the need in this part of the world, and further south, they do not constitute the promise of sustained increased levels of production that are required for significant help against the declining production seen in many of the worlds major oilfields. For some help in that direction it is necessary to head West. And so it is time for the review of the oil sands.

There is however, considerable controversy over the operation of the oil sands in Alberta, particularly from those objecting citing the mess that is made of the landscape. In general the illustrations of oil sand operations that are used, show the site during mining, where the black color of the sand tends to make for a dismal picture. It might be more informative to show what the sites are like afterwards. And so, as a prelude to more discussion, here is a photo of some reclaimed land. It is here that the wood bison (as opposed to buffalo) roam.
