This picture is from a Paleobiology Field Trip that I TAed last year. It is a little difficult to see but if you look at the ridge in the background you can see a V-shaped structure. This is a lava flow that filled in a stream valley (a lava dam if you will). This was taken in southern Utah. Utah is/was actually very volcanically active due to the rifting that is causing/has caused the Basin and Range that extends across Nevada. We have several lava flows and cinder cones that are scattered across the landscape. And no, this has no relation to Yellowstone what-so-ever.
