Notice that the abdomen isn't pruinose bluish-white, as it is in adult males. In fact, at this age the male looks like a female, except for the white patches in the wing which are not present in the female.
In addition, the front legs are tucked up behind the head. This is a common way for dragonflies to relax when they are perched, and is also common in flying dragonflies.
Eight-spotted Skimmers are featured in my field guide, Common Dragonflies and Damselflies of the Pacific Coast. Check out the spread devoted to these beautiful dragonflies:

This species is abundant at Heart Lake, and common at Little Cranberry Lake, as well.
