On one glorious fall day, I was guided by an expert in southern Berkshire County history to a little known cave site. Last year brought the same company together to explore the northern reaches of Monument Mountain but today's goal was to go into its western territory. Some poking around amongst the quarzite boulders and ledges revealed a high slot-like entrance descending into the nether regions. We were rewarded to a spacious room with vaulted ceilings. Obvious signs of past inhabitants were present. And if we chose not to exit by the same route, another entrance lay near the cavern's end, up and over a rock pile, then out into the daylight.
