Dragonflies, from the order Odonata, have been around for over 250 million years. The most conspicuous difference in their evolution over time is the steady shrinking of their wingspan from well over two and a half feet down to a few inches.
Four individual raindrops falling on the high peaks of the Rockies could easily end up thousands of miles apart -- one flowing north to the Beaufort Sea, another reaching the the Gulf of Mexico, a third would be absorbed into Hudson Bay to the east and the last into the vast Pacific.
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.

Building British Columbia
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.
Myomancy was a method of divination by mice. Their behaviour was observed and taken as a omen of what was to come. Modern scientists study the movements of mice more than the ancient myomancers did and for ends that are not dissimilar.

Plants are important in the fossil record because they are plentiful and provide valuable information about the climate, temperature, water cycle and humidity of a region.
Rare bird, reptile and mammal tracks have been immortalized in the outcrops of the Chuckanut Formation. Diatryma tracks have also been found there. These massive flightless birds reached up to 9 feet in height and made a living in the grasslands and swamps of the Eocene.
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.
One of the most beautiful drives in the Pacific Northwest is the coastline along the Olympic Peninsula from Port Angeles to Neah Bay. This stretch of road meanders alongside the Clallam Formation, a thick, mainly marine sequence of sandstones and siltstones that line the northwestern margin of the Olympic Peninsula, western Washington.
The Farallon Plate took a turn north some 57 million years ago, sweeping much of western coastal Oregon along with it. By the middle Oligocene, the Cascadia Subduction Zone was in full force with growing pressure erupting volcanoes along the Western Cascades, a pattern that was to continue well into the Miocene. The soft ocean sediments of Oregon contain beautifully preserved gastropods, bivalves and cephalopods.

rain or shine
Rain long foretold takes a long time to pass; if it arrives on short notice, it soon will pass. For the folks I go out collecting with all hikes, digs and kayak trips are rain or shine. Safety is always top of mind and prepping for the weather is paramount. Keep yourself safe whatever part of the world you choose to explore.
