Golden in Jefferson County, Colorado — The American Mountains (Southwest)
Follow sand layers laterally and vertically as they represent individual point bars. Note how layer 1 started out thick and pinched out as deposition migrated downstream. Looking closely, notice larger sand grains (and sometimes larger bones) at the base trending to smaller grains and no bones at the top.
The numbers in the photo and the drawing correspond to the different point bar deposits. The layer marked 1 was deposited first and is the oldest of the 3 layers.
