Button Bay State Park's flora reflects its position at the ecological crossroads of the Champlain Valley, where limestone-influenced soils support distinctive plant communities. The 14-acre Button Point Natural Area protects rare plant species growing from cracks in the limestone bedrock near the peninsula's tip. The park's mature forest areas feature typical Champlain Valley hardwoods including sugar maple, white oak, shagbark hickory, and basswood. The limestone substrate creates alkaline soil conditions favoring species uncommon in Vermont's generally acidic landscapes. Wetland areas support cattails, sedges, and other aquatic vegetation that filters water and provides wildlife habitat. The Button Point Trail passes through transitional zones where hardwood forest gives way to open areas with expansive lake views. Wildflowers bloom throughout the growing season in the park's meadow areas and forest understory. The park's botanical significance extends beyond its boundaries, contributing to understanding of Champlain Valley plant distributions and the ecology of limestone habitats in northeastern North America.

Button Bay State Park showcases exceptional geological features formed over hundreds of millions of years. The park's namesake button-like concretions formed when clay deposits consolidated around nuclei of organic matter or mineral grains, creating distinctive spherical formations found along the shoreline. The underlying bedrock consists primarily of Ordovician-age marine limestones deposited approximately 450 million years ago in shallow tropical seas. These tilted rock layers display numerous fossils including colonial corals, stromatoporoids, brachiopods, and other marine invertebrates that populated ancient seafloors. Button Island, visible offshore, features an 18-inch thick reef zone composed of tumbled coral heads preserved in the Orwell limestone. The Champlain Thrust, a major fault system visible in the regional geology, lifted and tilted these rocks during the Taconic mountain-building event. Glacial activity during the Pleistocene further shaped the landscape, depositing till and sculpting the shoreline. The park's geology attracts students and researchers studying paleontology, sedimentology, and structural geology, making Button Bay an outdoor classroom for earth science education.

Button Bay State Park experiences a humid continental climate moderated by the thermal influence of Lake Champlain. The large lake mass delays spring warming and extends fall warmth, creating growing conditions more favorable than areas away from the water. Summer temperatures are comfortable, with average highs in the upper 70s to low 80s Fahrenheit, while lake breezes provide natural air conditioning during hot periods. The park's location in the relatively low-elevation Champlain Valley receives less precipitation than Vermont's mountain regions, averaging approximately 36 inches annually. Winter brings cold temperatures and lake effect snow when winds blow across unfrozen water early in the season. The open exposure creates windy conditions, particularly during storms when waves can become quite large. Spring and fall often bring spectacular atmospheric displays as weather systems move through the valley. The park's climate supports the diverse flora adapted to the relatively mild Champlain Valley conditions, including some species reaching their northern limits in this temperate zone.

The Button Bay area has attracted human activity for thousands of years, beginning with Native American peoples who utilized Lake Champlain's resources for fishing, hunting, and transportation. The Champlain Valley served as a major north-south travel corridor connecting the St. Lawrence River region with the Hudson Valley, placing Button Bay along important indigenous trade routes. European exploration began with Samuel de Champlain's 1609 voyage, which gave the lake its name. Colonial settlement brought agriculture to the fertile valley, with farms established throughout the Ferrisburgh area in the late 18th and early 19th centuries. The limestone bedrock was quarried for building stone and lime production, leaving its mark on the local economy. Lake Champlain served as a major transportation artery for moving agricultural products and manufactured goods before railroads bypassed water routes. The region's strategic importance led to military activity during the Revolutionary War and War of 1812. By the 20th century, the area's scenic beauty and recreational potential attracted increasing attention from visitors seeking lakeside recreation.
