“The universe is under no obligation to make sense to you” -Neil deGrasse Tyson

I am a undergraduate geology student studying at SUNY New Paltz. The plants I like to identify are ferns, conifers, varieties of herbaceous plants and occasionally mosses and lichens (although many of these are rather difficult without a microscope). I enjoy studying why organisms live in certain environments. Especially in relation to rock and soil types. I am a geologist at heart, but anyone who has explored their own field in science will realizes they are all connected. That is why I am here… To relate geology to the biological world, to help me understand what I am looking at. Plants themselves tell you a lot about the topography, composition of rocks and soils, water table depth, pH levels, water drainage, temperature and so on. So remember to think more about the environment at large, whether it’s below your feet or even way up in the sky.

Story: I was hiking around the Lake George wilderness which is located in the Adirondacks of New York. in the area near Inman Pond and around the Adirondacks there are marbles which are largely composed of calcite and some graphite. I enjoy finding these outcrops even though they are rare and usually topped with mosses, lichens and all sorts of organisms. Hiking along you can find many outcrops like this. There was no detail to see what minerals were in the outcrop due to the plants and lichens but I noticed a plant which did tell me details of the outcrop without the minerals being visible. The moss was called Ontario Rhodobryum (Rhodobryum ontariense) ( This moss loves to grow in areas that have a source of calcium. They only grow near carbonate soils and rocks. Now to many geologists they would have walked home with zero knowledge of the outcrop (unless they destroyed it with a rock hammer which is not allowed in a state park) but I left with the knowledge that there was a marble somewhere in that valley because that plant was growing there. Either the moss was growing directly on the marble or somewhere nearby the marble was eroding away. I left happy with this knowledge.
