TRILOBITES

Trilobites — in all their many wonderful forms — lived in our ancient oceans for more than 270 million years. The last of their lineage went extinct at the end of the Permian, 252 million years ago.

WIDGEON ESTUARY

Interested in getting out on the water? Consider an easy day paddle or overnight to Widgeon Estuary. The paddling is easy. You can do the trip via kayak or canoe and stay for the night or do it as a day trip. There are spots all along the river. You can also camp near the base of the trail to the falls.

From Trail Peak:

There is nothing better than to cruise flat water with rippling reflections of big snowy mountains cascading off your bow.

The estuary of Widgeon Creek at the south end of Pitt Lake at Grant Narrows is the perfect place to enjoy this sensation.

If you like quiet peaceful waterways teaming with bird life this is the place to go for the whole estuary is a protected bird sanctuary. After making the 300m crossing of Grant Narrows, expect to see tons of waterfowl and other species from herons to Harlequins that make this area their habitat. You might even see a fleeting glimpse of muskrat or beaver if you are lucky.

If Widgeon Creek is high in the spring or early summer you can paddle quite a distance up under lazy overhanging branches draped in moss and lichen. Huge lush ferns and skunk cabbage line the shoreline in the marshy areas and neat little gravel bars are gathered in the bends of the creek. When you are there you will be amazed that you can be so close to the city yet so far away.

A campsite is located near the west end of the estuary if you want to stay longer. This is probably best to do in the shoulder season when it isn't so busy. If the water is high more secluded sites are located up the river.

CINQUE TERRE: LIGURIAN COASTLINE

Riomaggiore or Rimazuu in the local Ligurian language is a lovely seaside village that can trace its roots to the good taste of Monks who settled here in the early thirteenth century.

Here, great wine is produced and consumed along with a huge variety of seafood, figs, olives, capers and Limoncello in the wee restaurants and bars along the Via Colombo that look out onto the Gulf of Genoa.

Inspired by the praise of Dante, Petrarch and Boccaccio, I had the great pleasure to venture there with my friend, Guylaine. Drawn to the picturesque beauty of the Liguria region, ancient vineyards and the irresistible "photo a moment" scenery, we traveled from village-to-village, all along the Cinque Terre.

Liguria remains one of the wildest parts of the Ligurian littoral east of Genoa. The coastline is home to incredibly complex and exciting geology. It is composed of the Maritime Alps in the west and the Ligurian "nappies," continental margin ophiolities, of the Apennines in the east.

Along the coast, the north-northwest convergence of the Alpine orogeny gives way to the active east-northeast convergence along the Apennines. All of this tasty geology can be observed while walking from town to town from Riomaggiore through Manarola, Corniglia and Vernazza. We stayed in Monterosso al Mare during our visit, meeting up with friends and then visiting them in their home city of Milan. If one is lucky enough to be invited as a guest, the geology of the Via deli'Amore is true to its name sake and well worth the trip.

In my mind's eye, thinking back on the experience, I picture stormy seas, colorful rowboats, sheer cliffs and exotic meals of black squid pasta washed down with Albarola.

BOWRON BEAUTY


Yellow Lily line pathways and float in the cold, clear lake water. Somewhere I read a suggestion to bring a bathing suit to the park, but at the moment, I cannot imagine lowering anything more than my paddle into these icy waters.

To reach the west side of the paddling route, we must first face several kilometres portaging muddy trails to meet up with the Isaac River and then paddle rapids to grade two.

DIPLOGRAPTUS: GRAPTOLITES

Diplograptus
floating in Cambrian seas. These colonial animals are known from Middle Cambrian to Lower Carboniferous fossils. The name graptolite comes from the Greek graptos for written and lithos for rock — written on the rock.  And they do look a bit like scratches or calligraphy, but more so like primitive plants. I confess that when I found my first graptolite fossil, I had assumed this was a plant group, then looked them up and low and behold... aquatic sea animals!

MEGATHERIUM AMERICANUM

In 1788, this magnificent specimen of a Megatherium sloth was sent to the Royal Cabinet of Natural History from the Viceroyalty of Rio de la Plata.

The megaterios were large terrestrial sloths belonging to the group, Xenarthra. These herbivores inhabited large ares of land on the American continent. Their powerful skeleton enabled them to stand on their hind legs to reach leaves high in the trees, a huge advantage given the calories needed to be consumed each day to maintain their large size.

Avocados were one of the food preferences of our dear Giant ground sloths. They ate then pooped them out, spreading the pits far and wide. The next time you enjoy avocado toast, thank this large beastie. One of his ancestors may have had a hand (or butt) in your meal.

In 1788, Bru assembled the skeleton as you see it here. It is exhibited at the Museo Nacional De Ciencias Naturales in Madrid, Spain, in its original configuration for historic value. If you look closely, you'll see it is not anatomically correct. But all good paleontology is teamwork. Based upon the drawings of Juan Bautista Bru, George Cuvier used this specimen to describe the species for the very first time.

VIEW FROM ON HIGH

A view from on high. 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 majestic peak is said to have been one of the last areas of dry ground during a time of tremendous flooding in the Squamish basin.

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 majestic 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.

BLUE JAY: KWAS'KWAS

If you live in North American, there is a high probability that you have seen or heard the bird song of the Blue jay, Cyanocitta cristata (Linnaeus, 1758).

Blue Jays are in the family Corvidae — along with crows, ravens, rooks, magpies and jackdaws. They belong to a lineage of birds first seen in the Miocene — 25 million years ago. 

These beautifully plumed, blue, black and white birds can be found across southern Canada down to Florida. The distinctive blue you see in their feathers is a trick of the light. Their pigment, melanin, is actually a rather dull brown. The blue you see is caused by scattering light through modified cells on the surface of the feather as wee barbs.

Blue jays like to dine on nuts, seeds, suet, arthropods and some small vertebrates. 

If you are attempting to lure them to your yard with a bird feeder, they prefer those mounted on trays or posts versus hanging feeders. They will eat most anything you have on offer but sunflower seeds and peanuts are their favourites. 

They have a fondness for acorns and have been credited with helping expand the range of oak trees as the ice melted after the last glacial period.  

Their Binomial name, Cyanocitta cristata means, crested, blue chattering bird. I might have amended that to something less flattering, working in a Latin word or two for shrieks and screams — voce et gemitu or ululo et quiritor. While their plumage is a visual feast, their bird chatter leaves something to be desired. 

In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest and my family, a Blue Jay is known as kwa̱skwa̱s

The Kwak’wala word for blue is dzasa and cry is ḵ̕was'id. For interest, the word for bird song in Kwak'wala is t̕sa̱sḵwana. Both their songs and cries are quite helpful if you are an animal living nearby and concerned about predators.

FRESH FISH CONNOISSEURS

Ammonites were a group of hugely successful aquatic molluscs that looked like the still extant Nautilus, a coiled shellfish that lives off the southern coast of Asia.

While the Nautilus lived on, ammonites graced our waters from around 400 million years ago until the end of the Cretaceous, 65 million years. Varying in size from millimeters to meters across, ammonites are prized as both works of art and index fossils helping us date rock.

EQUUS FERUS CABALLUS

Small but majestic, these Icelandic horses have been bred to adapt perfectly to the rugged wilds of untamed Iceland. They hail from farther north, having been brought to Iceland by the Vikings.

One of the features of Icelandic horses is their small stature. Often mistaken for ponies, they are one of the oldest breeds of horses and while small, the registries do indeed list them as such. They boast a long life and an extra heavy double-layered coat, perfectly adapted to the harsh winter conditions of their homeland.

NAIKOON, HAIDA GWAII

A wreck with tales to tell at Naikoon in Haida Gwaii.

The islands have gone by many names. To the people who call the islands home, Haida Gwaii means “island of the people,” it is a shortened version of an earlier name, Haadala Gwaii-ai, or “taken out of concealment.” 

Back at the time of Nangkilslas, it was called Didakwaa Gwaii, or “shoreward country.” By any name, the islands are a place of rugged beauty and spirit and enjoy a special place in both the natural and supernatural world.

DEINOTHERIUM GIGANTEUM

Deinotherium giganteum















This partial specimen of Deinotherium giganteum hails from Cerecinos de Campos, Zamora from the Middle-Upper miocene (c. 15.97-5.33 Million Years)

The genus Deinotherium could reach a height of over 3.5 meters. Its structure and size are similar to those of the present-day elephant. Deinotherium first appeared approximately 17 million years ago and became extinct relatively recently, just 1.6 million years ago.

One of the distriguishing features of Deinotherium is their curved tusks inserted only in the jaw. One of the tusks from this fellow, on display at the Museo Nacional De Ciencias Naturales in Madrid, Spain, while incomplete, was preserved rather nicely and shows the detail of where the tusk meets the jaw.

MUIR WOODS, CRICKET THERMOMETER

Out in the woods and wondering what the temperature is? Slip down to the nearest stand of deciduous trees to search for the wee Snowy Tree Cricket, Oecanthus Fultoni, part of the order orthoptera.

Snowy Tree Crickets and their cousins double as thermometers and wee garden predators, dining on aphids and other wee beasties. Weather conditions, both hot and cold, affect the speed at which they rub the base of their wings together and consequently regulate their rate of chirping.

Listen for their tell-tale high pitch triple chirp sound in the early evening. Being in Canada, our crickets chirp in Celsius. Simply count the number of chirps over a seven second period and add five to learn your local temperature.

If didn't bring your calculator with you into the woods and you're still operating in old-skool Fahrenheit use this handy conversion. Double the temperature in Celsius, add 32 you'll get the approximate temperature in Fahrenheit.

This beautiful photo of Muir Woods outside San Francisco is by Aussie photographer, Paul McClure.

SCAPHOPODA: TUSK SHELLS

The Oligocene Lincoln Creek Formation has produced several dozen different species of infaunal molluscs, burrowing worms and is well-known for crabs.

This specimen is from the massive, tuffaceous siltstone and sandstone that runs through the town of Porter on the east side of the road.

The fossil-rich bedding planes are well-exposed with concretionary beds throughout.

Collecting was possible in the late 1990’s and early 2000’s but may be forbidden (or heavily discouraged today) as the site is on a busy roadway. I made multiple trips to Porter back in the day with folk from Vancouver and Washington State. The primary focus in the early 2000’s were the crabs. They were just in the early stages of being written-up and much excitement surrounded them.

But to each his own -- as it happens, this wee tusk shell is one of my favourite fossils from the site as my trips to Porter were focused mainly on the molluscs.

Tusk shells, are members of a class of shelled marine mollusc with a global distribution. Shells of species within this class range from about 0.5 to 15 cm in length. This fellow is 8 cm end to end, so near smack dab in the centre of his cohort.

The Scaphopoda get their nickname "tusk shells" because their shells are conical and slightly curved to the dorsal side, making the shells look like tiny tusks (picture a walrus or mammoth tusk in your mind’s eye). The scientific name Scaphopoda means "shovel foot," a term that refers to the "head" of the animal, which lacks eyes and is used for burrowing in marine sediments.

The most distinctive feature of scaphopods, however, and one that differentiates them from most molluscs, is the duo openings on their tubular shells. Most molluscs are open at just one end.

We could call scaphopods the great deniers. They live their adult lives with their heads literally buried in the sand. A tiny bit of their posterior end sticks up into the seawater for water exchange. Water is circulated around the mantle cavity by the action of numerous cilia.

When the available dissolved oxygen runs low for this fellow he ejects water from the yop end of his shell by contraction of his "foot."
