Rice Lake: Location and Background History
The Archaeologist David Boyle comments on Rice Lake in 1897:
Hundreds of acres of its surface are covered with wild rice, and it has thus been always a favourite resort for water-fowl. Fish, too. were formerly abundant, and no doubt deer and other large game were plentiful. As the Indians also used (and still use) the rice, it will be seen that all the conditions of primitive life in the neighbourhood were extremely favourable. Add to this the fact that the lake formed an important link in one of the two great canoe routes between the upper lakes and the St. Lawrence, and more especially between the Huron country and Lake Ontario, and we have another reason for this having been a desirable Indian resort.
Halfway between Toronto and Kingston above the north shore of Lake Ontario sits Rice Lake, a 30-kilometre long and narrow lake. As the quote above notes, it was part of a thousands-year-old water highway used by Indigenous Peoples to travel from Georgian Bay to Lake Ontario.
These days Rice Lake is a section of the Trent-Severn Waterway, a 386-kilometre canal whose final lock was completed in 1920.
During the period from 1650 to 1700, one of five nations of the Iroquois Confederacy (thought to be Cayuga) had a village on the north shore of Rice Lake. Before that, as the map below indicates, the Wendat, another Iroquoian people better known as the Huron, lived on Lake Ontario’s north shore and included Rice Lake as part of their territory.
Further back in time, other Indigenous cultural groups would have been familiar with the Rice Lake area and used it at least on a seasonal basis. Going back 2000 years, those peoples may have included those from the Algonkian (i.e.Anishinaabe) cultural family, which we associate with the Canadian Shield.
Hiawatha First Nation:
These days, the Hiawatha First Nation can be found on the shores of Rice Lake. The map below indicates their territory – about 2145 acres in all. It is located on the north side of the lake, across from the Alderville First Nation. The members of this First Nation are Mississauga Ojibwe and belong to the Algonkian/Anishinaabe family.
This recorded testimony (The Story of Paudash) would date their settling in the Rice Lake area around 1700 at the end of the Algonkian/Iroquois World War. The Mississaugas took over land abandoned by the Iroquois, who retreated to their Haudenosaunee heartland across Lake Ontario.
A map showing the extent of the original reserve set aside for them would undoubtedly show how much their territory has shrunk over the past 200 years.
Given that Hiawatha was a legendary/historical Onondaga chief and an Iroquoian hero, it is puzzling that this Anishinaabe First Nation is named after him. Longfellow’s 1855 poem The Song of Hiawatha is the cause of the confusion; he used the name Hiawatha for his clearly Ojibwe hero, whom he had initially wanted to name Manabozho (his spelling of Nanabush or Nenebuc, the mythic Anishinaabe hero). Mistakenly thinking that the two names were synonymous, Longfellow called him Hiawatha instead! See here for a full explanation. Despite Longfellow’s mistake, the First Nation perpetuates it by hanging on to the name.
Hiawatha First Nation territory includes an area on the north shore above Roach Point (some old maps name it Roche’s Point) which is significant as the location of what is said to be the only serpent effigy mound in Canada. In a statement from 1904, the then-chief Robert Paudash said this about the burial mound site –
At Rochis Point there was a Mohawk village in front of the former site of this is a mound in the shape of a serpent, having four smaller mounds about its head and body in the form of turtles. These mounds are a pictorial representation of the Mississaugas in memory of the occurrence, and of the Mohawks. It has been supposed by some to mean more than this, but my father has so stated it. [See here for the source.]
The serpent presumably represented the Iroquois, known by the uncomplimentary name Nadoways (the big snakes) to the Anishinaabe; the smaller mounds represent the Mississauga and their clan totem. If Chief Paudash is correct, the mounds date around 1700 C.E. and were built by his not-too-distant ancestors to commemorate their recent defeat of the “big snake.” However, the archaeological evidence indicates the mounds are much older, i.e. older by at least 1400 years.
David Boyle and the Serpent Mound Site:
David Boyle, the first archaeologist to examine the site, drew this conclusion in his 1897 report on the site:
… for the construction of the mounds cannot be attributed to any people with whom Europeans have come into contact. It is not recorded that the Huron-Iroquois were mound-builders, and we must therefore regard the earthworks in question as the product of a people who preceded them.
While their ancestors were not the builders of the burial mounds, the current members of the Hiawatha First Nation have become caretakers of the site.
The Canadian Encyclopedia summarizes the site’s significance this way –
Serpent Mounds, situated on a bluff overlooking Rice Lake near Peterborough, Ont, is the only known effigy mound in Canada. It is a sinuous earthen structure composed of six separate burial locations and measuring about 60 m long, 8 m wide and 1.5-1.8 m high. Excavation indicated that the mounds forming the effigy were gradually built up between 50 BCE and 300 CE. This would suggest that Serpent Mounds was a sacred place, visited periodically for religious ceremonies. Although pieces of grave furniture were not plentiful, their distribution shows they were restricted largely to individuals of higher status within the community. Those individuals were buried either at the base of the mounds or in shallow, submound pits. The commoners were randomly scattered throughout the mounds’ fill. See here for the source.
While the site is referred to as Serpent Mounds, only one mound is in the shape of a serpent (Mound E on the David Boyle sketch of the site). The other eight mounds are oval or circular and smaller than Mound E. All nine were burial mounds, as indicated by the skeletal remains uncovered by various archaeological teams.
Here is Boyle’s account of his realization that what he was examining was a serpent mound:
At frequent intervals during the excavation of the oval mound, I travelled backwards, forwards, and around the long zig-zag embankment, now that I began to feel certain as to its origin, puzzled to account for its configuration, and its relation, if any, to the more easterly structure on which we were at work. On one of those occasions, when standing on top of the ridge some fifty feet from the westerly extremity, it struck me as being strange that this end of the bank should taper so gradually that its terminating point could not be distinguished accurately within a foot or more. This suggested the idea of a mere beginning, or of failure on the part of the builders to complete their work, and the next thought was to examine the other end. Here, however, there was a very marked dissimilarity, for the bank rose at a sharp angle to a height of four feet and was much more expanded than any other portion of the mound. In the course of another walk along the earthwork I was struck with the thought that this was a serpent mound, but the idea seemed absurd to one who, on account of frequent disappointments, is prone to cast doubt on fanciful resemblances of every kind.
Still, there was the broad, abrupt head – there was the tapering tail, and between these were three well-marked convolutions – the zig-zags hitherto without meaning – not so prominent as those of the Adams County mound in Ohio, but, as I now think, much more natural.
Given Boyle’s account of his “discovery,” it does not sound like someone else told him it was a serpent. Like the tale of Archimedes in his bathtub shouting “Eureka,” we have Boyle, hesitant at first but soon surrendering to the realization that he was standing on a serpent effigy mound! And even more – seeing the Egg some forty feet away!
Some locals, Indigenous and non-, thought the mounds were built for defensive purposes during the Algonkian-Iroquois War of the late-1600s. Others, like Robert Paudash, quoted above, also identified the central mound as a serpent a few years after Boyle. In the Paudash account, the smaller mounds represented turtles. He said they had been built as a memorial to victory over the upstate New York Iroquois in the great war.

Is It Even A Serpent?
It was David Boyle who came up with the notion that what he was looking at was an effigy mound depicting a serpent and an egg. His drawing shows a somewhat serpentine figure with the “egg” just to the left of the mouth of the snake. The “serpent with egg” effigy is what Putman claimed to have found in Ohio a few years before, and Boyle would have been aware of it. It may have influenced how he interpreted what he saw at this burial mound site above Rice Lake. In turn, his serpent/egg interpretation has also determined what most people ever since are conditioned to see when they visit the Rice Lake site or read articles about it. To paraphrase St. Augustine – “Believing is seeing”!
Note: Boyle’s sketch is deceiving. The “serpent’s” head points in a northeasterly direction, not west, as in the illustration above. Here is another sketch of the site and some of the other mounds showing their correct orientation:
While the sketch above presents the correct orientation, it also copies the exaggerated zigzag shape of Boyle’s serpent and the overly narrow profile and the extended tail.
Henry Montgomery’s 1909 Excavation
In 1909 Henry Montgomery (see here for a brief bio) and a team of diggers did some archaeological work on the “serpent mound.”. The following year his report Recent Archaeological Investigations in Ontario appeared in the journal Transactions of the Canadian Institute (Vol. IX, Part 1, June ). In it, he expressed doubt about Boyle’s serpent interpretation and offers a plausible alternative explanation:
This is the earthwork to which the name “serpent” was given by Mr. Boyle. That it was intended by its builders to represent a serpent in shape is somewhat doubtful, there being little evidence in support of the view. There are but two convolutions in it ; whereas there are seven convolutions in the Adams County serpent mound of Ohio which latter is also more uniform and natural in form. It is possible that this Peterboro County mound may be an aggregation of ordinary burial mounds erected in this way at different times for convenience’ sake.
A page later, he does seem to equivocate when he writes this –
Although irregular, and in length relatively short, its shape is such that it might be regarded as the beginning of an unfinished serpent.
Among the measurements he provides is of a 40-foot stretch of the mound, which he states is 37 feet wide, about one-fifth of the length. These are not the proportions that come to mind with a serpent!
To appreciate a truly serpentine effigy mound, we turn to Adams Country.
The Serpent Mound in Adams County, Ohio
The Ohio serpent mound stretches 411 meters (1348′) from its coiled tail to its open jaws, which hold an oval shape, which was interpreted by Putman to be an egg, though it could be a frog or something else entirely.
He decided that the mound represented a serpent with an egg in its jaws. He believed it demonstrated a connection between Serpent Mound and various Old World cultures. Other archaeologists have documented parts of the mound that Putnam ignored, such as a wishbone-shaped earthwork that wrapped around the far side of the so-called egg. Evidently, Putnam felt this earthwork made no sense if the mound actually represented a serpent and an egg, so he didn’t restore it. [See here for the source of the quote]
Given the association of the mound with the Ancient Fort culture, which constructed it around 1000 years ago, approaching the mound’s meaning through the worldview and beliefs of the actual builders would be the way to go. [See here – and here! – for a couple of head-shaking examples of how people have explained the Ohio mound’s meaning and purpose!]
The mound is from 30 to 100 cm. high and 6 to 6.5 meters (20 to 25′) wide. Unlike the Rice Lake site, it was not a burial mound and served some other ritual purpose. The Rice Lake serpent is just as wide (an average of 6.5 meters) yet is 1/7th as long. The proportions are quite different; what we have at Rice Lake would be a short and very wide serpent!
Comparing the two mounds makes it fair to question Boyle’s interpretation. While one clearly and undeniably looks like a serpent, the other could be a tadpole! And while the Ohio one definitely has an oval shape which may be an Egg or something else within what one could interpret as its jaw, it is a stretch to interpret the Rice Lake mound as another rendition of a Serpent with Egg – and one that Boyle imagines is “much more natural”!
Richard Johnson – ROM/U of T 1955-1960
The most thorough examination of the Serpent Mounds site was done from 1955 to 1960 by a Royal Ontario Museum/University of Toronto team led by Richard Johnson. His report became his Ph.D. thesis a year later. The shortened version was published by U of Toronto Press as a ROM book in 1968. It is the essential source of information on the mounds.
The following sketch from the book provides a detailed view of the site and its various mounds. In their fieldwork, the ROM/U of T team noted two mounds (G and H) not recorded by previous visitors.
Look at the shape of the Mound E in the late 1950s/early 60s sketch and without having been told that the shape you are looking at is a snake, you would not likely have offered that up as an answer.
Noteworthy is that on the first page of Johnson’s study of the site, he twice states that it is not a given that Burial Mound E is a serpent and that “the name of the mound and site is regarded as entirely speculative.” However, the name “Serpent Mound” was so ingrained by the mid-1960s that Johnson felt he had to stick with it despite his severe reservations about its validity!
Here is the first page of the Johnson study of the site – the entire book can be accessed via a link below.
The ROM team conducted carbon dating at various points along the length of the burial mound. The dates ranged from 128 to 300 A.D. and, as Johnson wrote, “favour the assumption that construction continued intermittently over several years.” This is hardly a situation you would expect of a 194-foot-long effigy mound that could be created in a summer or two if that was the actual intent.
Walter Kenyon Still Sees a Serpent!
Walter Kenyon’s excellent summary Mounds of Sacred Earth: Burial Mounds of Ontario was published by the Royal Ontario Museum in 1986. In it, Kenyon provides a history of the sites and a history of the archaeological work that went into uncovering them. Over half the report is spent on the burial mounds of southern Ontario; Rice Lake and its outlet, the Trent River, is where most of them are found, including the ones at Roach Point.
The brief booklet might be the best introduction to the specifics of the burial mounds on the north shore of Lake Ontario. [The second half of the report deals with the Rainy River area mounds.] Two decades after Johnson and his reluctance to call Mound E a serpent – without even bringing in Mound F as the Egg! – Kenyon begins with this –
Kenyon unexpectedly begins by reinforcing Boyle’s burial mound as a serpent effigy! The site sketch he chose to use in his book is Boyle’s, with its exaggerated serpentine look and a slimmed-down width. The work of his ROM colleagues seems to have escaped his view.
He had started work at the ROM in 1956, just as Museum began its fieldwork on the Rice Lake Site at Roach Point. You’d think that over thirty years, the specific nature of the largest Rice Lake mound would have come up in the staff lunchroom in the ROM basement during winters spent examining artifacts from the various mounds and middens!
More recently, J.V. Wright, in his comprehensive A History Of The Native People of Canada [Volume II (1,000 BC – AD. 500)], summed up what I assume is the consensus view this way –
The Serpent Mounds site (Boyle 1897; Johnson 1968) consists of nine earth burial mounds, the most striking of which is the so-called Serpent Mound. The Serpent Mound appears to be more of a crooked linear mound that actually being intended to represent the form of a serpent….the mound represents a series of construction events that took place between AD 200 and 250. (Wright 675)
Some Sources on the “Serpent Mounds”:
The first trained archaeologist to examine the site and make public his findings was David Boyle in 1897 his report of the previous summer’s visit. Boyle was at the time perhaps Canada’s top archaeologist and had spent years focussing on the Indigenous cultures of Ontario. From 1896 to his death in 1911, he was also the director of the Ontario Provincial Museum, which morphed into the Royal Ontario Museum the following year.

Before a visit to the Diamond Lake pictograph site in Temagami, I read Boyle’s brief comments in a 1906 report on the site by W. Phillips, a “temporary assistant” working for Boyle and the Museum. (See here for Phillips’s report and Boyle’s comments.)
Boyle’s analysis proved to be mostly off-the-mark and showed little understanding of the purpose of pictographs in the culture of the Anishinaabe. Instead, he proposed an interpretation at variance with the facts. For a more in-depth consideration, see the following post –
Boyle was one of the first to grapple with the pictograph tradition and should probably be cut some slack!

The Internet Archive site has a copy of the thorough and detailed examination of the Serpent Mounds sites conducted over five years in the late 1950s by a Royal Ontario Museum/University of Toronto team led by Richard Johnson. In 2012 the ROM funded the inclusion of the digital version of the text in the Archives. The 150-page book includes at least 100 photos of stone, bone, and metal artifacts dug up, and the skeletal remains of some sixty humans interred at what was essentially a burial site. Such an excavation would likely not happen in these more sensitive times.

- Volume I (10,000 – 1000 B.C.)
- Volume II (1,000 B.C. – A.D. 500)
- Volume III (A.D.500 – European Contact)
A three-volume set that sifts through and synthesizes the massive amount of details from the archaeological record to reveal the history and the various cultures of Canada’s Indigenous Peoples before European contact. While it is comprehensive in its approach, Wright clearly has the non-archaeologist in mind and clearly explains critical terms and concepts. While not light reading, it shows how archaeologists have contributed to a better understanding of Canada’s Native PeopAfterfter he retired from The Natural Museum of Canada in 19Wright took on the writing 91, after thirty years of archaeological fieldwork and research for the institution. In his summary of 12,000 years of archaeological evidence in his bid to tell the story of Canada’s Indigenous Peoples, he wrote –
it is unacceptable that the 12,000 years of native human history in Canada prior to the arrival of the Europeans has been largely ignored simply because there are no pre-European written records. History based upon archaeological evidence has severe limitations but that is no reason for the record of past human behaviour to be ignored or rejected as irrelevant. (See here for the source)
Volume II’s chapter 23 (pp. 607-702) Late Great Lakes – St. Lawrence Culture provides the necessary background and context for the site at Rice Lake.
Serpentine. Andrew King.
Andrew King provides some speculative alt-history à la History Channel for those who like some fantasy with their dates and facts. See here for what seems to be a digital copy of the above book. His WordPress site can be accessed here. It is also where I found the coloured site image I used above.
In the first few pages, I read this –
…right here in Ontario, just a few hundreds kilometres west of Ottawa, there is another massive ancient serpent structure, but it remains closed off to the public. It is the only one of its kind in Canada but has been studied without current technical advances in archaeological resources.
This large snake effigy on Rice Lake, south of the village of Keene in Peterborough County, was constructed thousands of years ago, yet its greater purpose remains unknown. (bold face is mine)
The brief passage raises several obvious objections –
- “Massive ancient serpent” is certainly hyperbole for a 60 m x 6 m mostly linear earth structure.
- To state that “it remains closed off to the public” without explaining that it was the Hiawatha First Nation’s decision suggests an attempt to keep us – the public – from finding out some more profound truth about the mounds.
- More hyperbole in the statement that the archaeological work that has been done on it is somehow very dated. It also does not mention that further excavation work has been forbidden, thus limiting any possible future analysis to non-invasive techniques acceptable to the Hiawatha community.
- “Thousands of years ago” puts an unnecessarily distant past spin on what archaeologists agree is an Adena/Hopewell culture like the Point Peninsula culture of 1800 years ago in the eastern Lake Ontario region.
- As for its greater purpose remaining unknown, is its importance as a site where one of the four essential lifecycle rituals was conducted not enough? [The others being birth, puberty, and marriage…]
Visiting The Serpent Mounds in 2022?
For a look at what the Serpent Mounds site looks like these days, this Youtube video from 2018 (the only clip I found about the site) will give you an idea. The commentary is from two guys showing a fuzzy understanding of the site’s significance. Their choice of title for the video says it all! A trailer park!
As I watched it, I thought – How could Ontario Parks have supposed it was okay to set up a campground and children’s play area on a burial ground? Still unclear to me is if this was the idea of the leadership at Hiawatha First Nation or of the Ontario Parks people.
The Historic Site was taken over by the Hiawatha First Nation in 1995. By 2009 it was decided to close the park to visitors. It has remained closed ever since. Perhaps private visits can be arranged via a visit to or communication with the nearby First Nation. The author of Serpentine got permission to visit the site while researching material for his book.
Trip Advisor Forums and Comments:
Doing a search for “Serpent Mounds” and “Serpent Mounds Park” in the Tripadvisor Forum’s Ontario section turned up nothing… not one question or recommendation or comment. Given the site has been closed for 12 years, it seems to have slipped out of any discussion of southern Ontario Indigenous historic sites.
Tripadvisor has a few comments about Serpent Mounds Park, most sad because of the closing and the deteriorating condition of the site.
