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.

ORCHIDS: CREATIVE366PROJECT
In Greek mythology, Orchis was the son of a ugly a nymph and a satyr who came upon a festival for Dionysios deep in the woods. Liking his fermented grapes a wee bit too much, he overindulged on wine then tried to have his way with a priestess of Dionysios.
As a result the Bacchanalians tore him limb from limb. His grieving father prayed to the Gods for him to be restored. Not that keen on folk of his ilk but feeling kindly, they turned him into a flower instead.

BILATERAL SYMMETRY: BRACHIOPODS
Clams or bivalves are molluscs, the second-largest phylum of invertebrates with about 85,000 extant species. While brachiopods share some similarities with their molluscan friends they are in a phylum all their own.
Brachiopods are small marine shellfish that are not so common today but back in the Palaeozoic they were plentiful the world over. The two valves that make up a brachiopods shell are of different sizes and if you look closely you'll see that the hinge runs top and bottom -- versus left and right like a clam.
Their lineage dates back to the Cambrian with over 12,000 fossil species and 350 living relatives sorted between 6,000 genera. There are two major groups of brachiopods, articulate with toothed hinges and simple open and closing muscles to manipulate their shells and inarticulate brachiopods with untoothed hinges and a more complex set of muscles used to control the brachial supports used to open and close their shells.

OREGON FOSSIL MAMMALS
More than 100 groups of mammals have been found in the Miocene (37 – 20 mya) John Day Formation near Kimberly, Oregon. I'm planning a field trip this July to collect in the fossiliferous strata that have yielded beautifully preserved speciments of many of the animals we see domesticated today.
Dogs, cats, swine and horses are common. Oreodonts, camels, rhinoceras and rodents have also been found in this ancient deciduous forested area.

ANCIENT ANTACID: MIDDENS
Many First Nations sites were inhabited continually for centuries. The discarded shells and scraps of bone from their food formed enormous mounds called middens. Left over time, these unwanted dinner scraps can transform through a quiet process of preservation. Time and pressure leach the calcium carbonate, CaCO3, from the surrounding marine shells and help “embalm” bone and antler artifacts that would otherwise decay. Calcium carbonate is a chemical compound that shares the typical properties of other carbonates.
CaCO3 is common in rocks and shells and is a useful antacid for those of you with touchy stomachs. In prepping fossil specimens embedded in limestone, it is useful to know that it reacts with stronger acids, releasing carbon dioxide: CaCO3(s) + 2HCl(aq) → CaCl2(aq) + CO2(g) + H2O(l)
For those of you wildly interested in the properties of CaCO3, may also find it interesting to note that calcium carbonate also releases carbon dioxide on when heated to greater than 840°C, to form calcium oxide or quicklime, reaction enthalpy 178 kJ / mole: CaCO3 → CaO + CO2.
Calcium carbonate reacts with water saturated with carbon dioxide to form the soluble calcium bicarbonate. Bone already contains calcium carbonate, as well as calcium phosphate, Ca2, but it is also made of protein, cells and living tissue.
Decaying bone acts as a sort of natural sponge that wicks in the calcium carbonate displaced from the shells. As protein decays inside the bone, it is replaced by the incoming calcium carbonate, making the bone harder and thus more durable.
The shells, beautiful in their own right, make the surrounding soil more alkaline, helping to preserve the bone and turning the dinner scraps into exquisite scientific specimens for future generations.

PLATE TECTONICS & PINOT GRIS
Sipping a glass of Sandhill, I'm thankful for plate tectonics and the cultivation of the pinot gris grape.
