ISOGRAPTUS MAXIMUS
Graptolites (Graptolita) are colonial animals. The biological affinities of the graptolites have always been debatable. Originally regarded as being related to the hydrozoans, graptolites are now considered to be related to the pterobranchs, a rare group of modern marine animals.
The graptolites are now classed as hemichordates (phylum Hemichordata), a primitive group which probably shares a common ancestry with the vertebrates.
In life, many graptolites appear to have been planktonic, drifting freely on the surface of ancient seas or attached to floating seaweed by means of a slender thread. Some forms of graptolite lived attached to the sea-floor by a root-like base. Graptolite fossils are often found in shales and slates. The deceased planktonic graptolites would sink down to and settle on the sea floor, eventually becoming entombed in the sediment and are thus well preserved.
Graptolite fossils are found flattened along the bedding plane of the rocks in which they occur. They vary in shape, but are most commonly dendritic or branching (such as Dictoyonema), saw-blade like, or "tuning fork" shaped (such as Didymograptus murchisoni).
This fellow is pure "Bat Sign" with his showy "wings" looking like something out of a DC Comic. He's also received a nod as the Panem symbol in Hunger Games and been described as having eagle or angel wings. No matter how you interpret his symbolism, there is not doubt that he is spectacular. He is in the collection of the deeply awesome Gilberto Juárez Huarachi from Tarija, Bolivia.

SUMAS EOCENE SITE
Once the skies cleared, hikers found plant impressions in the rock and alerted the local paleo community. I was invited to tag along on a trip to photograph the site while George Mustoe took moulds of the palm trunks and trackways.
The slide site at Sumas Mountain revealed many large exposures of fossil plants. Some exposures were 10 feet across. There was great excitement at seeing shorebird tracks and trackways of the large flightless bird Diatryma. Many of these finds can now be seen at the Burke Museum in Washington State. While less abundant, evidence of the animals that called this ancient swamp home are also found here. Rare bird, reptile, and mammal tracks have been immortalized in the soft muds along ancient riverways.

MOON RAVEN TOTEM AT SAXMAN TOTEM PARK
Moon Raven Pole at Saxman Totem Park |
The art of totem pole carving was a luxury that experienced its heyday in the mid-1700s to the late 1800s.
In the late 1800s, Tlingits from the old villages of Cape Fox and Tongass searched out the Saxman site as a place where they could build a school and a church.

OYSTER: TLOXTLOX
While rare today, these are British Columbia’s only native oyster. Had you been dining on their brethren in the 1800s or earlier, it would have been this species you were consuming. Middens from Port Hardy to California are built from Ostrea lurida.
These wonderful invertebrates bare their souls with every bite. Have they lived in cold water, deep beneath the sea away from the suns rays and heat? Are they the rough and tumbled beach denizens whose thick shells have formed to withstand the pounding of the sea?
Is the oyster in your mouth thin and slimy having just done the nasty spurred by the warming waters of Spring? Is this oyster a local or was it shipped to your current local and if asked would greet you with "Kon'nichiwa?" Not if the beauty on your plate is indeed Ostrea lurida.
We have been cultivating, indeed maximizing the influx of invasive species to the cold waters of the Salish Sea. But in the wild waters off the coast of British Columbia is the last natural abundant habitat of the tasty Ostrea lurida in the pristine waters of Nootka Sound. The area is home to the Nuu-chah-nulth First Nations who have consumed this species boiled or steamed for thousands of years. Here these ancient oysters not only survive but thrive — building reefs and providing habitat for crab, anemones and small marine animals.
Oysters are in the family Ostreidae — the true oysters. Their lineage evolved in the Early Triassic — 251 - 247 million years ago.
In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest, an oyster is known as t̕łox̱t̕łox̱. I am curious to learn if any of the Nuu-chah-nulth have a different word for an oyster. If you happen to know, I would be grateful to learn.

ELASMOSAURS: GRIT & GASTROLITHS
Gastroliths – round, polished stomach stones – have been found amid their bones. These stones would have been swallowed to help grind down their catch and lower their natural buoyancy. In their selection of these pebbles, elasmosaurs displayed, at times, a remarkable geological discernment.
The Puntledge elasmosaur from Courtenay, British Columbia, for example, had a yen for basalt. When the fossilized skeleton was excavated, the stones in its abdominal cavity were all basalt, an indication that this particular elasmosaur had somehow learned to discriminate between basalt stones and all others.
Basalt, as any geologist will tell you, is harder (and therefore longer lasting as a grinding material) than many other rocks. Yet over time, even basalt will erode, particularly when subjected to the digestive juices of such an enormous creature. From the elasmosaur’s long neck and bulky body, paleontologists have concluded that that their fishing technique was probably a sudden snake-like strike with the head, sweeping the meal into their cage-like mouth long before the tell-tail body loomed in sight through the depths.
Swimming beneath a school of fish, they would have been hidden by their dappled camouflage, allowing them to swing their toothy mouths up into the schools and capture hapless fish to be swallowed whole. Less stealth was probably required to hunt ammonites – free-swimming shellfish that jetted along like armoured squid. During the Jurassic, ammonites, distant relatives of the chambered nautilus, populated the seas.
The ammonites’ heavy protection would have meant that their backward-looking view of the world was no problem when dealing with most predators, but the marine reptiles of the day were a fatal exception to the rule. Ammonite fossils with clear teeth marks have been found, putting both elasmosaurs and mosasaurs at the scene of the crime and solving murder mysteries millions of years old.

STAWAMUS CHIEF: SQUAMISH RISING
Eagles, bears and breathtakingly beautiful scenery await those who travel north of Vancouver, British Columbia to the town of Squamish.
I had the great pleasure of meeting one of those travelers last evening while enjoying a stunning sunset dinner at the Boathouse on Kitsilano Beach -- Barbara Samways, a delightfully interesting woman and wonderful conversationist out exploring the West Coast via tour and rail.
British by descent, Barbara has traveled the world. living in what was once Rhodesia, now Zimbabwe, and finally settling down in the isolated beauty that is Perth. We talked of the world's great beauties and a shared love of travel with friends and family. Canada is new to her and a geologic playground that I love to call home.
While we lack the turquoise waters and kaleidoscope of colorful fish that warmer waters offer, I wax poetic about our deep blue Pacific, mountain peaks, rich geologic and interesting early history -- all of the things that captivate me and I hope she'll enjoy. I'm looking forward to meeting up with her after her three-week sojourn to hear what sights from our young country delighted her, viewed from a fresh set of eyes.
Situated at the head of Howe Sound and surrounded by mountains, Squamish is cradled in natural beauty as only a West Coast community can be. Growing in fame as the Outdoor Recreation Capital of Canada, visitors will discover the abundance of attractions, activities and opportunities to explore in this wilderness community.
Before Europeans came to the Squamish Valley, the area was inhabited by the Squohomish tribes. These Indians lived in North Vancouver and came to the Squamish Valley to hunt and fish. The first contact the Indians had with the white man was in 1792, when Captain George Vancouver came to Squamish to trade near the residential area of Brackendale.
During the 1850s gold miners came in search of gold and an easier gold route to the Interior. Settlers began arriving in the area in 1889, with the majority of them being farmers relocating to the Squamish Valley. The first school was built in 1893 and the first hotel opened in 1902, on the old dock in Squamish.
Squamish means Mother of the Wind in Coast Salish, which is testimony to the winds that rise from the north before noon and blow steadily until dusk, making Squamish a top wind surfing destination, and host to the annual PRO-AM sailboard races.
The Stawamus Chief, the second largest freestanding piece of granite in the world, has made Squamish one of the top rock climbing destinations in North America. This magestic peak is said to have been one of the last areas of dry ground during a time of tremendous flooding in the Squamish area.
Many cultures have a flood myth in their oral history and the Coast Salish people of Squamish are no exception. They tell of a time when all the world save the highest peaks were submerged and only one of their nation survived. Warned in a vision, a warrior of the Squamish nation escaped to safety atop Mount Chuckigh (Mount Garibaldi) as the waters rose.
After the flood, a magestic eagle came to him with a gift of salmon to tell him that the world below was again hospitable and ready for his return. He climbed down the mountain and returned to find his village covered by a layer of silt.
All his people had perished, but the gods gave him another gift, a second survivor of the flood, a beautiful woman who became his wife. For their gift of generosity they had shown, the couple took the eagle as their chief totem and have honored it through generations of Coast Salish people.
