Some wonderful range shots. My research suggests that those trees are ponderosa pine. They get more yellow as they get older and smell sweet like vanilla or maple syrup. Now I have a urge to smell more trees.
Here is a link to where I got my info:)

Nice article you linked too, I bet your right about it being a ponderosa pine. I thought of it as a pitch pine after talking to people who talked about finding logs full of pitch, that they referred to as a pitch pine. I guess a pitch pine grows in a different area though. They are fun to smell because they are a bit different from tree to tree and some are very fragrant.
