National Parks trip – Grand Tetons

 

I know, I know.  I have been absent and have failed to fulfill my complement of bitching and grousing.

I will return to that subject but first – another trip, this time to three US National Parks; the Grand Tetons, Yellowstone and Glacier.  My wife and I took this trip in May, starting at the Grand Tetons then moving north first through Yellowstone and then Glacier.  Taking the trip early in the season meant some chanciness in the weather.  The Grand Tetons had some rainy weather but we got an improvement in Yellowstone and Glacier.  We also got a look at a number of critters including black bears and a grizzly.  More on that later.

First up, the Grand Tetons.

The first four pictures are the classic one (though a bit cloudy) of the Snake River in the foreground and the Tetons in the background.  The Tetons are unusual in that, unlike most mountain ranges (the Rockies, the Appalachians, the Cascades and Sierra Nevada’s), they rise directly from a flat valley without any foothills.  It’s all due to tectonic activity and the fact that one tectonic plate is moving directly under another and, as one plate rises, erosion levels the valley floor.  At times, it is as though there is a flat valley floor and the Tetons are huge fake drapery to convince you that there are mountains.

During our visit, we took the boat ride across Jenny Lake and the next picture shows the approach to the landing dock.  A hike with a 600 foot in elevation change took us to hidden falls (next picture).

A Mormon community attempted to establish a farming community in the latter part of the nineteenth century and this barn is often captured in photographs of the now abandoned buildings of that community.

Next is a picture taken from our bedroom balcony at the Jackson Lake Lodge and the last is one on our departure to Yellowstone as the weather cleared.
