TANGIERS: ANCIENT TUSKS
During the Miocene and Pliocene, 12-1.6 million years ago, a diverse group of extinct proboscideans, elephant-like animals walked the Earth.
Most of these large beasts had four tusks and likely a trunk similar to modern elephants. They were creatures of legend, inspiring myths and stories of fanciful creatures to the first humans to encounter them.
Beyond our neanderthal friends, one such fellow was Quintus Sertorius, a Roman statesman come general, who grew up in Umbria. Born into a world at war just two years before the Romans sacked Corinth to bring Greece under Roman rule, Quintus lived much of his life as a military man far from his native Norcia. Around 81 BC, he travelled to Morocco, the land of opium, massive trilobites and the birthplace of Antaeus, the legendary North African ogre who was killed by the Greek hero Heracles.
The locals tell a tale that Quintus requested proof of Antaeus, hard evidence he could bring back to Rome to support their tales so they took him to a mound at Tingis, Morocco, where they unearthed the bones of a Neogene elephant, Tetralophodon.
Tetralophodon bones are large and skeletons singularly impressive. Impressive enough to be taken for something else entirely. By all accounts these proboscidean remains were that of the mythical ogre Antaeus and were thus reported back to Rome as such. It was hundreds of years later before their true heritage was known.

FOSSILS AND RED OCHRE
Around 45-50 million years ago, during the middle Eocene, a number of freshwater lakes appeared in an arc extending from Smithers in northern British Columbia, south through the modern Cariboo, to Kamloops, the Nicola Valley, Princeton and finally, Republic, WA.
The lakes likely formed after a period of faulting created depressions in the ground, producing a number of basins or grabens into which water collected - imagine gorgeous smallish lakes similar to Cultus Lake near Chiliwack, British Columbia.
The groaning Earth, pressured by the collision of tectonic plates producted a series of erupting volcanoes around the Pacific Northwest. These spouting volcanoes blew fine-grained ash into the atmosphere and it rained down on the land. The ash washed into the lakes and because of its texture, and possibly because of low water oxygen levels on the bottoms that slowed decay beautifully preserved the dead remains of plant, invertebrate, and fish fossils - some in wonderful detail.
In and around the town of Princeton, there are many places to collect. The fossils you find here are all middle Eocene, Allenby Formation and most have a high degree of detail in their preservation.
A crack of the hammer yields fossil maple, alder, fir, pine, dawn redwood and ginko fossil material. Several species of fossilized insects can be found in the area and rare, occasional fossil flowers and small, perfectly preserved fish. It is also home to one of the world's oldest bee's - a find by Rene Saveneye - naturalist and keen paleo hunter who will be much missed.

LOVE YOUR WORLD. BE IDLE FREE
I met two enthusiastic environmentalist today, Megan and Eric, who would like us to take up a couple of easy habits to do our part. They are raising awareness around greenhouse gas emissions and what you can do to make a difference. Idling your engine for more than 10 seconds uses more fuel and causes more emissions that turning it off entirely and restarting it.
So, what can you do? Turn off your vehicle while waiting at train crossings, schools, drive-thrus, community centres and other places you may need to wait in the car. They recommend you drive your vehicle to warm it up rather than idling the engine and telling others to stop their engine, helping them save money and protect the environment.
If you have trouble remembering, keep a delicious bar of dark chocolate on hand at all times and a small post-it note that reads, "turn off your car and indulge yourself." Eating antioxidant-rich chocolate is good for your brain and will help you save the environment. Make your own commitment to be healthy, green and idle free!

POND SCUM... AND OTHER HOT SPRING BEAUTIES
Slimeball, a derogative term to be sure from the modern usage, but before it was ever dragged down to the world of insults and verbal nastiness we know it for today, the scum of which we speak and the small bacteria that form them were simply the catalysts for the many beautiful colours we see in hot springs.
While a whole host of thermophilic (heat-loving) microorganisms are responsible, it is the cyanobacteria, one of the more common fellows from this group, which form most of the scum. Cyanobacteria grow together in huge colonies (bacterial mats) that form the delightfully colourful scums and slimes on the sides of hot springs.
You can tell a fair bit about the water temperature and chemistry by just looking at the colour of the pools… as cyanobacteria, while not considered picky pool dwellers, do prefer one pool to another. So, the next time you hear someone fling this insult your way, stop and tell them how attractive scum make this world.

TSAXIS: BEAVER HARBOUR HISTORY
The Big House at Tsaxis designed by Tony Hunt |
Coal was discovered in the adjacent area in 1849 and the Hudson’s Bay Company made the decision to open a coal mine and build a fort the same year.
The supply of coal in the area was short-lived and overtaken by new fields developed at Nanaimo.
Although the fort was initially built to protect the coal mining operation, it immediately became the hub of colonial activity along the central coast of British Columbia and northern Vancouver Island. It remained an important post for trade and resupply for the remainder of the 19th Century.
Sadly, most of the records—-reports and financial accounts—-from Fort Rupert have been lost.
Robert Hunt had been the last Hudson’s Bay Company Factor (Chief Trader) at Fort Rupert. The records show that he started as a labourer for the HBC in 1850, at £25 per year. His salary was quickly doubled shortly after he started at Fort Rupert. I am guessing that many salaries went up at that time on the Northwest Coast, because the discovery of gold in California in 1849 led to a labour shortage. Robert Hunt met and married Mary Ebbets, a Tlingit noblewoman from Tongass, Alaska.
Robert Hunt’s brother, who I believe came round Cape Horn with him on the HBC ship the “Norman Morrison”, disappears from the historical record at this time. Did he head off to California?
From the few remaining records from the 1870s, we learn that Robert Hunt was the last HBC Factor and then its owner. Robert Hunt passed it to his daughter Jane Charity and her husband Harry Tennyson Cadwallader.
His immediate superiors at Fort Victoria were pleased with his work, his ingenuity in keeping the fort in good repair, and with his reliability. As many of you know, Robert ended up purchasing the fort, including 600 acres of land, in the 1880s. I have not been able to locate any records or reports from Robert’s time at his one-man post on the Nass River.
Cousin Alec Hunt, who drove trucks up to Port Hardy in the late sixties, and often visited with mom and dad, told my cousin John Lyon that according to family lore, Aunt Lizzie, George and Sarah’s sister, was born up north while Robert ran the trading post on the Nass River.
Four Kwakwaka’wakw families (septs) settled at Fort Rupert to exploit the trading opportunities the post presented. These groups came to be known collectively as the Kwagu'ł (pronounced Kwa-gyu-thl) or Fort Rupert Kwakiutl Band.
These groups are identified by Galois (1994) as Walas Kwakiutl (Lakwilala), Komkiutis, Kwakiutl (Kwágu7lh), and Kweeha (Komoyoi).
A catastrophic episode occurred at the village in 1865. Captain Nicholas Edward Brooke Turnour, commanding the British Navy's steam corvette Clio, arrived at the Fort to demand the surrender of three Fort Rupert Kwagu'ł charged with murdering an a man from Nawitti.After issuing a number of ultimatums, the Navy ship shelled the adjacent village, often referred to as Ku-Kultz, destroying a large section of it, in addition to about 60 canoes.
According to anthropologst Johan Adrian Jacobsen, there in 1881, the Navy attack severely impacted the village and its inhabitants.
Many moved across the strait to the inlets of the mainland, while another 250 to 300 returned and rebuilt the devastated village. (Gough, 1984: 82-84).
There is an image here of Tsaxis circa 1866 by Franz Boas detailing the house ownership by Kwakwaka’wakw family.

GONDWANA: ANCIENT LIFE
Free of ice and the giant marine and flying reptiles, a new line-up of mammals, flightless birds, crocodiles, snakes and turtles thrived in the warm, wet climate, rapidly adapting and dominating the forests, oceans and skies.
New and fanciful creatures, the monotremes, marsupials and placentals explored and took root in the Gondwanan forests as conifers gave way to broad-leaved trees in an ever changing landscape.

ANCIENT WETLAND
This ancient wetland provided ideal conditions to preserve the many trees, shrubs & plants that thrived here. Plants are important in the fossil record because they are more abundant and can give us a lot of information about climate, temperature, the water cycle and humidity of the region.
The Chuckanut flora is made up predominantly of plants whose modern relatives live in tropical areas such as Mexico and Central America. If you are interesting in viewing a tropical paradise in your own backyard, look no further than the Chuckanut.
Glyptostrobus, the Chinese swamp cypress, is perhaps the most common plant found here. Also abundant are fossilized remains of the North American bald cypress, Taxodium; Metasequoia (dawn redwood), Lygodium (climbing fern), large Sabal (palm) and leaves from a variety of broad leaf angiosperm plants such as (witch hazel), Laurus (laurel), Ficus (fig) and Platanus (sycamore), and several other forms.

WOLVERINE RIVER: DINOSAUR SITE
Their discovery spurred an infusion of tourism and research in the area. The Hudson's Hope Museum has an extensive collection of terrestrial and marine fossils from the area. They feature ichthysaurs, a marine reptile and hadrosaur tracks.
At a British Columbia Paleontological Symposium in Tumbler Ridge, I joined Jen Becker for an impromtu late night tour of Wolverine River. There are two types of footprints at the Wolverine River Tracksite, carnivorous theropods and plant eating ankylosaurs.
During the day, the trackways at Wolverine are difficult to see. Many of the prints are so shallow that they can only be recognized by the skin impressions pressed into the tracks. By night, we filled them water and lit them by lamplight to make them stand out, reflecting the light.

PADDLING BEFORE THE FRONT
Some 270 million plus years ago, had one wanted to buy waterfront property in what is now British Columbia, you’d be looking somewhere between Prince George and the Alberta border. The rest of the province had yet to arrive but would be made up of over twenty major terranes from around the Pacific. The rock that would eventually become the Cariboo Mountains and form the lakes and valleys of Bowron was far out in the Pacific Ocean, down near the equator.
With tectonic shifting, these rocks drifted north-eastward, riding their continental plate, until they collided with and joined the Cordillera in what is now British Columbia. Continued pressure and volcanic activity helped create the tremendous slopes of the Cariboo Range we see today with repeated bouts of glaciation during the Pleistocene carving their final shape. Warm and dry with bellies filled full of soup and crisps, we head back out to explore more of nature's bounty.

HATSHEPSUT: FIFTH PHARAOH OF THE 18TH DYNASTY
Here she is lovingly carved out of indurated limestone, a fitting homage as Hatshepsut is regarded by Egyptologists as one of the most successful pharaohs, reigning longer than any other woman of an indigenous Egyptian dynasty.
This piece, originally from Hathshepsut's temple at Deir el-Bahri, now resides at the Metropolitan Museum of Art in New York.

TECTONIC FORCES: PACIFIC NORTHWEST
Over vast expanses of time, powerful tectonic forces have massaged the western edge of the continent, smashing together a seemingly endless number of islands to produce what we now know as North America and the Pacific Northwest. Intuition tells us that the earth’s crust is a permanent, fixed outer shell – terra firma.
Aside from the rare event of an earthquake or the eruption of Mount St. Helen’s, our world seems unchanging, the landscape constant. In fact, it has been on the move for billions of years and continues to shift each day.
As the earth’s core began cooling, some 4.5 billion years ago, plates, small bits of continental crust, have become larger and smaller as they are swept up in or swept under their neighboring plates. Large chunks of the ocean floor have been uplifted, shifted and now find themselves thousands of miles in the air, part of mountain chains far from the ocean today or carved by glacial ice into valleys and basins.
Two hundred million years ago, Washington was two large islands, bits of continent on the move westward, eventually bumping up against the North American continent and calling it home. Even with their new fixed address, the shifting continues; the more extreme movement has subsided laterally and continues vertically.
The upthrusting of plates continues to move our mountain ranges skyward – the path of least resistance. This dynamic movement has created the landscape we see today and helped form the fossil record that tells much of the recent history of the Pacific Northwest.

FROZEN IN TIME: MAMMOTHS
Because of their massive size and icy cold environment, many mammoths have been preserved as frozen carcasses instead of being turned to stone, thus they are prime candidates for genetic reproduction. When originally touted in the news as a possibility, most audiences took the science to be too far fetched.
Researchers harvesting DNA and deciphering their genome feel they are on the edge of doing just that. Science as we know it is sliding down the double helix to science fiction. DNA, long bits of genetic code that form the roadmap of how we are built, is relatively easy to harvest and remarkably hardy.
Even with the abuse of time, small amounts can be extracted and with that the genetic wizards are able to put the puzzle pieces back together. Frozen sperm is used in fertility clinics around the globe, the difference here is that the entire mammal is frozen before harvesting the sperm. Once harvested, the frozen sperm from long extinct male mammoths is injected into eggs from females of closely related species.
While positive results have been made and papers published (see the National Academy of Sciences) a baby mammoth has yet to be conceived.
