This little guy looked like a jumping spider but was in the wash area of the Usery Mountain trial, I used a stick just to get it to stop for his portrait, and it reared back and bared its fangs - impressive - rather than a crab like walk it skittered along fairly quickly. About a month later we saw another just like it except the red coloring was markedly lighter, almost light orange. We blended to photos to give a couple of different views.
