A Fault Line

this area is the same i remember me and my brothers went fishing at around chelatchie back in the middle 70's in washington state. at that time my family was liveing around amboy and hockinson wa.

Who told you that this was a fault line? Do you know what a fault line is?

Well first off, I do know what a fault line is, and I ask if you do? A fault line is a term used in geology to refer to a fracture in a rock where one side of the rock has moved in relation to the other part. Faults can be found all over the world and can be different sizes. Here is another fault that I have posted. Second, I was taken to this fault line while I was in a Geology class.

In general, the term "fault line" is applied to larger bodies of rock, while the word "fracture" is more commonly used to describe similar phenomena in smaller rock.

And in response to your question, yes, I do know what a fault line is, and have extensive knowledge of them.

Steve how can you tell how extensive this fault body is from that one picture? This is in fact a picture showing a small portion of a much larger fault system verified by the USGS.

Jeremy, I would have to ask you the same question. How would you know for certain that this is a picture of a small portion of a much larger fault system just by viewing a single picture? On a small scale, this type of phenomenon occurs commonly, totally unrelated to any larger fault systems.

So just because the USGS provides verification of a fault system in this region, do you automatically assume that what you see in this photograph is part of it?

If I am unable to definitively determine the nature of what appears in this image, then like wise, neither are you. ;)
