Hells Canyon excursion

 Flat bottomed jet boats make for an interesting trip, but the key is the boat captain. Ours took the smooth way up the rapids. The other boat went right up the back pounding way. It is worthwhile on the right boat. Popular recreation area, with float trips, fishing, camping, beaches with sand coming down from Salmon River.  

Geological development

 Every time I resume my blog it takes a while for me to remember how to post photos. Hence the delay. Much easier to post on FB.  Anyway, going back about 17 million years, volcanic eruptions covered the entire Snake and Columbia River valleys and tens of thousands of square miles in lava flows. Then a mere million years ago a series of glacial lake floods (Missoula floods) carved, created and displaced the Columbia and Snake into what they are today. Basalt rock can be seen along the sides of the Hells Canyon area of the Snake River.  

Following Lewis and Clark

 On a Snake and Columbia Rivers cruise with American Cruise Lines. Flight from JFK to Spokane. Beautiful drive down to Clarkston. Just harvested wheat fields, still with tracks from the equipment. But approaching Clarkston, elevation drops dramatically (2700’ along the way) and summer temperatures rise and terrain turns into dry rugged high desert.
