This is a Harvestman. They are is class Arachnida, but a different order, Opiliones, than Spiders. There are some interesting species of them on the West Coast. We specialize in Spiders, so unfortunately I don’t know the ID more specifically. https://en.wikipedia.org/wiki/Opiliones They aren’t dangerous at all to people, they do not have fangs nor venom. Unlike Spiders, Harvestmen have the ability to chew food.
