Well besides the obvious, we are going to talk about soil. Adams Cemetery is situated within the Connecticut Valley Lowland, a region shaped by geological events spanning tens of thousands of years. Approximately 70,000 years ago, as ice and snow accumulated across New England, it exceeded the rate of summer melting. Over time, this ice thickened to over a mile in depth, reshaping the landscape beneath it. The glacier, at its peak around 35,000 years ago, extended across Massachusetts in a south-southwest direction, carrying soil and rock as it moved. This glacial movement scoured and shaped the Earth's surface.
As temperatures fluctuated, the glacier's size and thickness varied, eventually beginning to retreat about 12,000 to 15,000 years ago from the area now known as Long Island Sound. The complete retreat of the glacier from this region occurred approximately 9,000 years ago. During this retreat, meltwater from the glacier flooded the land, forming temporary lakes and altering the topography. The vast Connecticut Valley Lowland was submerged for centuries, forming what is now known as glacial Lake Hitchcock, stretching from Wilbraham's Main Street westward to the Berkshires' foothills and from the Vermont border southward to Meriden, Connecticut.
As the Earth's crust gradually rebounded from the immense weight of the ice, glacial Lake Hitchcock drained away, leaving behind varied soils and terrain. Wilbraham, largely unchanged since the draining of Lake Hitchcock, retains distinct soil types derived from this glacial legacy. The mountainous areas and higher elevations in town are characterized by bouldery soils from glacial till, while lowland areas feature sandy or mucky soils from ancient lake-bottom sediments.
Today, beneath Adams Cemetery, these geological processes are evident in the layered composition of the soil. The uppermost layer consists of loamy soil, followed by clay-type soil beneath it, with sandy soil forming the deepest layer. Rocks are sparse in this area, reflecting the glacial history and subsequent soil development over millennia.
Understanding this geological history provides insight into the unique landscape beneath Adams Cemetery and highlights the enduring impact of glaciation on the region's soil composition and topography.
