Eastern Washington 2002-2003

Panorama looking west at a roadcut along I-82 on Umtanum Ridge; note broad anticlinal structure
and the thrust fault in left-center of the photo
 

Columbia River Basalt flows near Vantage; note good three-fold columnar jointing
(colonnade-entablature-colonnade) of central flow and more irregular pillow structure of top flow
 

The Twin Sisters in Wallula Gap. The platform of the twin sisters is the lower colonnade
of a flow, and the sisters are made up of the entablature of the same flow
(two-fold columnar jointing: colonnade-entablature)
 

Southeast-dipping Columbia River Basalts in the northwestern limb of a syncline
across the Columbia from Mosier, Oregon
 

Maryhill Museum above the Columbia River; note the large landslide immediately
behind the museam!
 

Touchet beds exposed in Burlingame Canyon south of Lowden, these rhythmic beds were
were deposited in a series of glacial outburst floods across eastern Washington, where the
floods backed up behind the a ridge of the Olympic-Wallowa Lineament
 

A small cobble drop-stone of granitic rock in the Touchet beds north of Touchet; the
rock was delivered to this location by floating in an iceberg in the floods
 

Clastic dikes in the Touchet beds north of Touchet, yes these are really vertical!
 

A row of windmills of the Stateline Windfarm south of the Walla Walla
Valley; this is currently the largest windfarm in the world.  Note: the dark green
boxes below the windmills are two meters high!
