A friend posted a picture of this and nobody knows what it is. She lives in Kelowna BC.
Though is it named for the Golden State, the range of the California Root Borer, Prionus californicus, extends well beyond California as you can see from the sighting data on BugGuide. According to BugGuide: “Larva feed primarily on living deciduous trees (oaks, madrone, cottonwood) and are also recorded from roots of vines, grasses, and decomposing hardwoods and conifers. Will also attack fruit trees growing on light, well-drained soils (e.g. apple, cherry, peach).” This individual is a male which can be distinguished from the female by his developed, distinctly sawlike antennae.
