Spring has Sprung and the rock lichens are visible now that the snow is gone from the north face of the cliff outside the cottage on Sugar Mountain Farm. When we built our tiny cottage in 2005 we set it into a nook in the cliff face that we had carved out of the bedrock of Sugar Mountain. This protects us from the cold north winds and gives a little micro-climate around the cottage.
Lichens Loving the North Face
During the past nine years the rocks of the cliff face have gone from bare raw crystals to virtually completely covered in lichens and mosses as well as other growing things. It has been a fascinating transformation from lifeless to life filled.
This is the northern equivelant of the coral reefs that I dearly love to study. On the shield face rock at the top one can see long scrape marks which were left by the glaciers as they dragged harder rocks against the bedrock which they ground smooth as they shaved off the top of our mountain about 15,000 years ago. Had it not been for the glaciers I would be a lot higher.
What is truly amazing is that after the glaciers retreated they left all of the land they had covered barren and dead. Then slowly lichens, mosses, shrubbery and Monty Python fans repopulated the naked rocks. By the time our people several thousand years later New England was filled with life. The ability of life to spring back from the edge of extinction is truly amazing.
