The siltstones, sandstones, mudstones and conglomerates of the Chuckanut Formation were laid down about 40-54 million years ago during the Eocene epoch, a time of luxuriant plant growth in the subtropical flood plain that covered much of the Pacific Northwest.

Like most mountainous areas, Bowron makes its own weather system and it appears you get everything in a 24-hour period. In fact, whatever weather you are enjoying seems to change 40 minutes later; good for rain, bad for sun. Wisps of cloud that seemed light and airy only hours early have become dark. Careful to hug the shore, we are ready for a quick escape from lightening as thundershowers break.

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.

Ever wonder why the slow moving sloth has a slightly greenish hue? Ever consider the sloth at all? Well, perhaps not. Location, location, location, is the mantra for many of us in our macro world, but it is also true for the small world of algae.

Co-ordination of flight requires tremendous brainpower, and co-ordination of active flight, with the constant shift in the shape and location of massive wings, even more so. Nature is extremely parsimonious, not frittering away investment in any organ where it is not needed.

Had you been swimming with the marine fossils that were laid down in the Eocene Epoch in Oregon, some 55 to 38 million years ago, you'd be treading water right up to where the Cascade Mountains are today. 

The Farallon Plate took a turn north some 57 million years ago, sweeping much of western coastal Oregon along with it. The Cascades were beginning to uplift and were fast becoming the breakwater for a retreating Pacific Ocean.

The enormous difference between high and low tide in Haida Gwaii – up to twenty three vertical feet – means that twice a day, vast swathes of shellfish are unveiled, free for the taking.

An ancient Haida saying is still often heard today, “When the tide is out, the table is set.”

Dinosaurs, long hailed as the rulers of the Triassic almost lost the title belt to a group of crocodilian upstarts, the crurotarsans. In a short lived battle for survival, geologically speaking, the two groups ran head-to-head for about thirty million years.

The Crurotarsi or "cross-ankles" as they are affectionately known, are a group of archosaurs - formerly known as Pseudosuchians when paleontologist Paul Serono, the darling of National Geographic, renamed them for their node-based clade in 1991.
