Escaping the latest oestrus moving ridge along the Colorado Front Range, my married adult woman in addition to I volition endure visiting friends inwards Ketchikan, Alaska, over the adjacent several days.  There nosotros volition taste afternoon highs inwards the 60s (F) in addition to overnight lows inwards the 50s; of course, pelting showers are equally good inwards the forecast, equally i mightiness await inwards Southeast Alaska.

As I discussed in Alaska's Collage of Terranes, nearly of the State is a mosaic of exotic terranes in addition to volcanic isle arcs, subsequently molded yesteryear glaciers, earthquakes, volcanic eruptions, torrents of meltwater in addition to fluctuating body of body of water levels.  Ketchikan sits inwards the Gravina Belt, composed of mid Jurassic to early on Cenozoic volcanic rocks, sandwiched betwixt the Alexander Terrane, to the west, in addition to the Stikine Terrane, to the east.  The Alexander Terrane is particularly interesting; its Silurian in addition to Devonian strata in addition to their cargo of fossils signal that it was torn away from Siberia equally the Northern Pacific opened.  The Stikine Terrane, on the other hand, formed equally a volcanic isle arc from the belatedly Paleozoic Era into the early on Mesozoic.

Today, Ketchikan, sitting on the Inside Passage, is a cruise send port during the summertime months.  Having express fourth dimension for our journey, nosotros volition endure flight from Denver (with a plane alter inwards Seattle).  More on our endangerment inwards upcoming posts.
