Poison Ivy or Poison Oak?

Is this the stuff? This was alongside the trail that we hiked last weekend. It looks like it to me, but I’m not positive. Thoughts?

    Definitely poison oak. If you’re in the San Gabriels, lookout for “Poodle Dog bush”, which also has urushiol. You won’t find any poison ivy in the western US, AFAIK.

    That’s the stuff! Poison oak for sure.
