Seeing nature at the edge of where a species existence is possible shows the very edge of life, absolutely love your effort and photos, trees are a subject I want to photograph more and more. In the forest it is challenging to photograph a single tree, these Bristle cones above tree line are unique and gobsmacking beautiful.
Did you have any problems with battery working in your camera at -30 degrees windchill. Have heard stories of battery problems in sub freezing temperatures. Love your work, thanks for sharing.
