Three miles away I found the rock pictured below. It is so unusual to my New England trained eye that I am convinced it is from another planet. My geologist friends [who have not actually seen the rock] laugh at me, and say it is simply a glacial erratic. That could explain how it got to the bicycle path, but what about those pockets? My geologic imagination sees them as trapped gas bubbles in cooling molten material from a thousand million years ago when volcanos were sending lava all over Amherst, Pelham, and Hadley. After that a broken piece of lava was smoothed down to its current size by waves on the beach of Lake Hitchcock. Finally, a glacier delivered it to the bicycle path, like all the other rocks around here.

Geologists, you are accustomed to outrageous propositions! Please weigh in....
