Like everyone else right now, I’ve been partially stuck inside practicing social distancing as part of our society’s duty to mitigate the spread of COVID-19. I say “partially” because luckily one can also socially distance while spending time outdoors, and Ithaca is the perfect place. After all, why not use this opportunity to explore the beautiful area surrounding Cornell and hike some new trails? On quite a few trails during my recent hikes in various nature preserves, I’ve noticed square or rectangular indentations in the ground nearby, sometimes lined with stone. Over a hundred years ago, these earthen depressions were the cellars of houses that are now long gone.
