Perhaps I am not the only one who is a unclear about your request. Are you asking for pictures of cedar shakes/shingles, lumber, arrows, etcetera? If so, I do not think they are likely to be so visually distinctive from other wood, such as redwood, that they will be of much help for identification.

If you are asking for tree pictures, then I suspect any field guide or online guide will do the job. I suspect there is Western Red Cedar on or very near your property, because there is a lot of it in the Sierras. The foliage in particular is distinctive and reminiscent of redwood.

I find the combined look, smell, and feel of cedar are the easiest identifier. It is a relatively light and coarse-grained usually reddish wood with a distincvtive aroma when cut or bruised. I would check some out at a home supply or lumber store to get the experience of look, feel, and smell.
