THE PYRAMIDS OF GIZA: FOSSILS IN BUILDING STONE
Rising from the desert sands of Egypt’s Giza Plateau, these monuments were constructed from a masterful blend of limestone, granite, basalt, gypsum mortar, and baked mud bricks—materials quarried both locally and from distant sites along the Nile, including the red granite of Aswan.
Their smooth, once-glimmering exteriors were clad in fine-grained white limestone quarried from Tura, just across the river. This stone was prized in antiquity for its purity and brilliant color, chosen for the facing stones of Egypt’s wealthiest tombs.
But beyond its beauty lies a story much older than any pharaoh. The Tura limestone is made almost entirely of the fossilized shells of Nummulites—single-celled marine organisms whose remains whisper of Egypt’s ancient seas.
First described by Lamarck in 1801, Nummulites are large foraminifera—amoeba-like protists with calcareous, chambered shells (or “tests”). In life, they resembled tiny white discs, their interiors patterned like concentric rings of a sliced tree or the cross-section of a shell.
During the early Cenozoic, millions of these creatures thrived in the warm, shallow waters of the Tethys Sea. When they died, their calcium carbonate shells settled to the seafloor, accumulating over millennia. Layer upon layer, they were compacted and cemented by time and pressure into limestone—the same rock later quarried to build the tombs of kings.

The pyramid itself—a monument to human ambition—is, quite literally, built from the remains of ancient seas.
Nummulites are commonly found in Eocene to Miocene marine rocks across southwest Asia and the Mediterranean region, including the fossil-rich Eocene limestones of Egypt. In life, they ranged in size from a mere 1.3 cm (0.5 inches) to an impressive 5 cm (2 inches), and in some Middle Eocene species, up to six inches across—astonishingly large for single-celled organisms.
Their size reflects an evolutionary adaptation: by expanding their surface area, they enhanced diffusion, allowing for more efficient nutrient exchange across the cell membrane. Many also harbored symbiotic algae, much like modern reef-dwelling foraminifera, further fueling their growth through photosynthesis.

The Great Pyramid’s inner chambers tell a different geological story. The central burial chamber housing the pharaoh’s sarcophagus was constructed from massive blocks of reddish-pink granite transported from Aswan, nearly 900 kilometers upriver. This stone, denser and stronger than limestone, helped support the immense weight of the pyramid’s structure.
In 2013, archaeologists made a discovery that breathed life back into these ancient logistics: a 4,600-year-old papyrus scroll found in a cave some 700 kilometers from Giza.
The document—addressed to Ankh-haf, half-brother of Pharaoh Khufu—records the journey of a 200-man crew tasked with transporting limestone from the Tura quarries to the Giza Plateau. After loading the stone blocks onto boats, the workers sailed down the Nile, where as many as 100,000 laborers waited to haul the two- to three-ton blocks up earthen ramps toward the construction site. It is a rare and poetic glimpse into one of humanity’s most ambitious building projects—and into the transformation of fossil limestone into enduring architecture.
Even in antiquity, the project stirred strong opinions. Writing centuries later, the Greek historian Herodotus visited Egypt and chronicled Khufu’s reign in his Histories. He described Khufu as a cruel tyrant who closed temples, oppressed his people, and forced them into servitude. According to Herodotus, 100,000 men labored in three-month rotations to quarry and transport the stone, while another decade was spent constructing the grand causeway leading to the pyramid—a feat of engineering almost as impressive as the monument itself.
Modern estimates suggest that 5.5 million tonnes of nummulitic limestone, 8,000 tonnes of granite, and 500,000 tonnes of gypsum mortar were used to complete the Great Pyramid. Whether viewed as an act of divine devotion, human hubris, or cruel genius, its creation also represents one of the largest—and most extraordinary—paleontological extractions in history.
For within its weathered stones, the fossils of an ancient sea still rest, silent witnesses to both deep time and the enduring reach of human imagination.

WIDGEON ESTUARY
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
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.

MEGATHERIUM AMERICANUM
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
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.

FOSSILS, BEES AND FIRST NATIONS HISTORY
My Norwegian cousins on my mother's side call them humle. Norway is a wonderful place to be something wild as the wild places have not been disturbed by our hands. Head out for a walk in the wild flowers and the sounds you will hear are the wind and the bees en masse amongst the flowers.
There are an impressive thirty-five species of bumblebee species that call Norway hjem (home), and one, Bombus consobrinus, boasts the longest tongue that they use to feast solely on Monkshood, genus Aconitum, you may know by the name Wolf's-bane.
In the Kwak̓wala language of the Kwakwaka'wakw, speakers of Kwak'wala, and my family on my father's side in the Pacific Northwest, bumblebees are known as ha̱mdzalat̕si — though I wonder if this is actually the word for a honey bee, Apis mellifera, as ha̱mdzat̕si is the word for a beehive.
I have a special fondness for all bees and look for them both in the garden and in First Nation art.
Bumblebees' habit of rolling around in flowers gives us a sense that these industrious insects are also playful. In First Nation art they provide levity — comic relief along with their cousins the mosquitoes and wasps — as First Nation dancers wear masks made to mimic their round faces, big round eyes and pointy stingers.
A bit of artistic license is taken with their forms as each mask may have up to six stingers. The dancers weave amongst the watchful audience and swoop down to playfully give many of the guests a good, albeit gentle, poke.
Honey bees actually do a little dance when they get back to the nest with news of an exciting new place to forage — truly they do. Bumblebees do not do a wee bee dance when they come home pleased with themselves from a successful foraging mission, but they do rush around excitedly, running to and fro to share their excitement. They are social learners, so this behaviour can signal those heading out to join them as they return to the perfect patch of wildflowers.
Bumblebees are quite passive and usually sting in defense of their nest or if they feel threatened. Female bumblebees can sting several times and live on afterwards — unlike honeybees who hold back on their single sting as its barbs hook in once used and their exit shears it off, marking their demise.They are important buzz pollinators both for our food crops and our wildflowers. Their wings beat at 130 times or more per second, literally shaking the pollen off the flowers with their vibration.
And they truly are busy bees, spending their days fully focused on their work. Bumblebees collect and carry pollen and nectar back to the nest which may be as much as 25% to 75% of their body weight.
And they are courteous — as they harvest each flower, they mark them with a particular scent to help others in their group know that the nectar is gone.
The food they bring back to the nest is eaten to keep the hive healthy but is not used to make honey as each new season's queen bees hibernate over the winter and emerge reinvigorated to seek a new hive each Spring. She will choose a new site, primarily underground depending on the bumblebee species, and then set to work building wax cells for each of her fertilized eggs.
Bumblebees are quite hardy. The plentiful hairs on their bodies are coated in oils that provide them with natural waterproofing. They can also generate more heat than their smaller, slender honey bee cousins, so they remain productive workers in cooler weather.
We see the first bumblebees arise in the fossil record 100 million years ago and diversify alongside the earliest flowering plants. Their evolution is an entangled dance with the pollen and varied array of flowers that colour our world.We have found many wonderful examples within the fossil record, including a rather famous Eocene fossil bee found by a dear friend and naturalist who has left this Earth, Rene Savenye.
His namesake, H. Savenyei, is a lovely fossil halictine bee from Early Eocene deposits near Quilchena, British Columbia — and the first bee body-fossil known from the Okanagan Highlands — and indeed from Canada.
It is a fitting homage, as bees symbolize honesty, playfulness and willingness to serve the community in our local First Nation lore and around the world — something Rene did his whole life.

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.
