Perspective Snowy Backcountry Boulders
Trees growing out of large boulders are always a photographic target . Particularly with a LOT trees growing out of boulders. On the crest of this backcountry ridge, this is a sand tube area where sand was compressed into an elongated sphere early on when it was first buried but still soft and wet. This is ALL Hell Creek Sandstone which routinely flows around internally a bit like soft putty. Sort of like squeezing a tooth paste tube. . This leaves these relatively harder boulders for me to enjoy as they resist weathering better than the material around them.
Deposited in the Cretaceous era about 66 million years old as an age. That lichen can be 100 years or more old. Only rocks that are undisturbed have big lichen patches. Cattle pressure/wear from rubbing will destroy it. This boulder is way out there remote. Not a lot of people have been to this spot. I see wonderful sunsets from here.
Big areas of this boulder strewn surface covered with Sunburst Liichen (Xanthoria sp.) exists here. Called pincushion lichen by some. Bear in mind that there are hundreds of different species of Lichen that inhabit Wyoming and differentiating them exactly is sort of a science all by itself. Lichenologists have to have work of some kind. Academia is the obvious job path. I suspect that there is a use for court testimony however the job prospects of a Lichenologist is about the same as a masters in biostratigraphy such as myself. Though interestingly, biostratigraphers do a lot of work with oil companies .. My general comment about Lichen nomenclature is that you need a bachelors of science in Biology (which I have) to look at the photos. The text about the lichen is a foreign language.😀😀.
