An erRATic in “Michigan’s Salad Bowl”
Geologists define erratics as stones or boulders that have been carried from their place of origin by a glacier and then left stranded by melting ice on bedrock of a different composition. Most glacial erratics appear worn and rounded, and sometimes include beveled or faceted surfaces. During the course of their journey, the rocks were jostled against other erratics or scraped against the underlying bedrock, rounding off corners and planing smooth surfaces, eventually producing their characteristic appearance. Glacial transport also caused some boulders to fracture, producing fresh angular edges. Rocks carried by rivers also undergo abrasion and become rounded in the process
Two major rock types are found in Michigan. The Lower Peninsula and the eastern parts of the Upper Peninsula are underlaid by a series of sedimentary rock layers. These rock formations consist largely of shales, limestones, and sandstones. The various layers of sedimentary rock are piled up on top of one another like a series of saucers. Igneous and metamorphic rocks compose the western part of the Upper Peninsula make up the second category of rocks. Igneous rocks are hard, crystalline, resistant to erosion, and are largely made up of granites and metamorphic rocks — rocks that have been changed through heat and pressure — composed mainly of gneisses and schists. Both major types of rocks found in Michigan are important to humans. The igneous type contains valuable minerals such as iron ore and copper, and the sedimentary rocks contain petroleum, natural gas, salt, gypsum, and limestone <>
Hudsonville was named after one of the earliest settlers, Homer E, Hudson, who was born in Cleveland, but moved to this area in 1848. He bought land in Georgetown Township from the Jenison brothers, which he developed into a nursery with fruit trees. This was the beginning of the many orchards throughout the state. Other settlers joined Hudson and a small community sprang up. They ran a farm and one of the many sawmills in the area. Growth of the town was steady, but never spectacular. It helped when, in 1873, Homer deeded twenty acres to the community and recorded it as the village of Hudsonville, however, swampland on three sides hampered development. Previously the settlement had been called South Georgetown. In 1872 the Chicago and West Michigan Railroad came through, a factor in subsequent arrival Of Dutch immigrants. The train went from Grand Rapids to Holland and on to Chicago passing through Hudsonville. The Dutch immigrants who arrived in the 1890’s from the low wetlands of their country turned the Tamarack Swamp, surrounding Hudsonville on three sides, from wasteland into productive farms. They produced onions, celery, carrots and other truck farm crops which is why for many years Hudsonville was called the “Celery Center.” Hudsonville is also known as "Michigan's Salad Bowl" because of the crops grown in the muck fields. Celery, onions, carrots, and other vegetables are prominent throughout the many acres of wet, fertile soil that once was an ancient river bottom.
Between 1941 and 1945, many young men from the community were killed in action during World War II. They were first remembered at the Memorial Park on School Street and more recently, at the Veterans Memorial Park on Central Boulevard next to the city offices. – which is where this erratic is located.
