Travels in Geology: Rafting the Salmon River through the Idaho Batholith

Rafting down the Main Salmon River, which courses north and then west across northern Idaho, takes you by Precambrian metamorphics and the granites of the Idaho Batholith. Six to eight days later, your trip concludes as you float past what was once the edge of North America, and over former island arcs sutured onto the continent during the Mesozoic.

fixed blade

fixed blade . Portion of longitudinal axis on upper side of platformed pectiniform conodont elements between free blade and carina; fixed blade is flanked by platforms (TIP, 1981, pt. W, supp.2).

corrasion

corrasion (cor-ra'-sion). (a) A process of erosion whereby rocks and soil are mechanically removed or worn away by the abrasive action of solid materials moved along by wind, waves, running water, glaciers, or gravity; e.g., the wearing-away of the bed and banks of a stream by the cutting, scraping, scratching, and scouring effects of a sediment load carried by the stream, or the sawing and grinding action of sand, gravel, and boulders hurled by waves and currents against a shore. The term has also been used for the loosening of rock material by the impact of rushing water itself, and was used by Penck (1953, p.112) for the "freeing of loosened rock fragments from their place of origin". The term "abrasion" is essentially synonymous. Syn: mechanical erosion. (b) A term sometimes used as a syn. of attrition. (c) A term formerly used as a syn. of corrosion, or as including the work of corrosion. The term was first used by Powell (1875, p.205) for channel cutting or the deepening of any valley floor and was extended by Gilbert (1877, p.101) to the work of all running water (including lateral corrasion). Verb: corrade.

(from Dictionary.com)

In today’s world, social media obsess over a small handful of entertainment, athletic, political, and business celebrities. It’s easy and tempting for the remaining seven billion of us to emulate, follow, and live vicariously through these few – breathlessly following ups and downs of the run-up (?) to a North Korean- U.S. summit, Meghan’s marriage to Harry, LeBron’s 50+ points Friday night, Roseanne’s latest tweet. We lose sight of reality – that we are, each of us, intended to be the heroes and heroines of our own lives.

What’s more, we’re not actors in some low-key sitcom, but rather a great drama – the challenge of living on the generous, dangerous, fragile real world.

wetland

wetland . An area that is regularly wet or flooded and has a water table that stands at or above the land surface for at least part of the year (NOAA, 2004). The term has supplanted more colloquial terms such as swamp and marsh.
