Curious large formation of rock above falls, with similar appearance to much smaller grooves carved in rocks below.

Mesa Cortina trail, August 13. I have taken this shot many years and have never been able to capture the impack of the shades of green and the harshness (and richness) of the view. Marsha, I believe, took this shot.

Mesa Cortina trail, August 13. "Beetle killed" Lodgepole Pine. Colorado's rich Lodgepole pine forests have been desimated by an outbreak of Lodgepole Pine Beetles (AKA, mountain pine beetles). A long drought reduced sap content in the trees, leaving them unable to expell beetles as they burrow into their bark. The trees eventually die of a virus carried by the beetles.
