what is the topographic relief of the Columbia River?
106793
The river falls a total of 2,690 feet (820 m)from the source to the outfall at the Pacific Ocean. The origin of the Columbia River that flows through Washington and Oregon is generally considered to be Columbia Lake in British Columbia, Canada.  \n\nHere is a map of the entire course of the Columbia:\nhttp://www.spokaneoutdoors.com/collakmp.htm

Plains, mountains, valleys, beach, escarpment, plateaus, prairie, continent, island, peninsula, delta, canyon, alluvial plain, etc.\n\nThese sites should help with more details..

you can spend years here....zorathustrn granite,mica schists..various volcanics  in  canyons bottem  are  evidence trhat  an old mountain range...some say  as  high as  todays  rockies...[by base measurments]  was  eroded away  by  ice flows.....oceans came  and  left.....on  ariving  plant and  animal life  contribute  fossil remains and  calcite[the  making of limestone]mud stones and shales....the  various  banding  give us  ideas to the duration  andlife  of the times.....basically  the  areas  above the  river  are  sandstones  shales  and  mudstone....but there is  marble and dolomites....explore....thers  gotta  b   pics  on  net  somewhere

I grew up in Washington State, and ended up in Washington DC (ok the DC 'burbs).  I miss the REAL mountains, Puget Sound and the beauty of everything about the Pacific Northwest.  But I've been over here in the DC area over 20 years and grown used to the heat and humidity, the beltway, and all the other things that drove me crazy when I first moved here.  I guess I'm settled in.  Besides, I have a great job that really can't exist anywhere else.  So here I am.  The Shenandoah mountains will never compare to the Cascades, but the nearby Atlantic ocean beaches have warm swimmable water in the summer - one thing the frigid waters off the Washington coast will never have!

Here is a website taken from a book titled "California Rivers and Streams" that does an excellent job of explaining river channel morphology. \nhttp://www.ucpress.edu/books/pages/6664/6664.ch04.html\n\nIt discusses and explains channel cross sections, channel patterns of both single and multichannel rivers, channel patterns in deltas, and includes both diagrams and a list of references. The book is an excellent resource even if you are not specifically interested in California Rivers.

Dude, you should definitely go tothe Chinook River. That place is clean, and people have been known to cathc really large fish up there.

The rivers are cresting and there is a lot of standing ground water that will slowly be absorbed or drain off.

The USGS publishes topographical maps with all mining claims shown.  It takes a lot of them to cover the whole state.

1) Evaporation.  The world's largest ocean is on one side of the peninsula, Puget Sound is on the other.  More water evaporates from the ocean that from the sound.\n\n2)  Elevation.  The water from the ocean side of the peninsula does not make it to the sound side of the peninsula because of elevation.  As elevation rises, it forces clouds to go up where the air can hold less moisture.  The clouds then lose their moisture as precipitation while getting over the hump.  The moisture never makes it eastward.

Go hike the waterfalls along the Columbia river gorge.  Beautiful, active, and the bounus of wearing the kids out so they will go to sleep earlier or take a nap.

Welll, that's a toughie.  There's not really a specific monument/edifice/bridge that is associated with Columbia (for example, the Eiffel Tower with France, or Statue of Liberty with U.S.).  However, the walled, old colonial town of Cartagena is quite beautiful and fairly well-known in photographs.  Or, you could do an old Spanish fort.  There are fotos at:  www.cartagenafotos.com\n\nOr, there are stone monuments that are associated with Columbia; they are part-men and part-jaguar.  Or, you could do a 3D of the Andes mountains.\n\nGood luck!
