The History of Block Island

Block Island has a rich history and has been inhabited by various groups of people throughout the last few hundred years. The island was initially inhabited by the Narragansett tribe, who called the island Manisses, meaning “little island.” The first European settlement on Block Island was established in the early 1600s by Dutch settlers. In 1664, the English took control of the island and it became part of the Colony of Rhode Island and Providence Plantations.

Throughout the 17th and 18th centuries, Block Island was a popular location for fishing and farming. The island also played a role in the American Revolution, with residents providing supplies and support to the Continental Army. In the 19th century, Block Island became a popular summer resort destination for wealthy families from the mainland.

Today, Block Island is a popular tourist destination, known for its beautiful beaches, historic sites, and unique atmosphere. The island is also home to a thriving fishing industry, with many local fishermen still fishing the waters around the island. The island’s population is around 1,000 year-round residents, with a summer population that can swell to several times that number.

Geological Formation of Block Island

Block Island is a small island located off the coast of Rhode Island in the Atlantic Ocean. It’s a glacial outlier, which means it was formed by glaciers that moved across the area during the last ice age nearly 10,000 years ago. The island is composed primarily of sedimentary rocks such as sandstone, shale, and siltstone, which were laid down in ancient seas and river systems and later exposed by the erosive power of the Atlantic Ocean’s wind and water.

Block Island is home to 365 freshwater ponds, one for each day of the year. The presence of so many freshwater ponds on Block Island is due to the island’s unique geology and hydrology. The island’s permeable sandstone and siltstone layers allow rainwater to filter into the ground and recharge the island’s aquifer. Over time, this groundwater has formed numerous ponds and wetlands that provide habitats for a wide variety of wildlife and plants. In addition to its geological features, the island’s location on the Atlantic coast and its exposure to the prevailing westerly winds have also played a role in shaping its hydrology.

Overall, the geological formation of Block Island has played a critical role in shaping its unique landscape and ecosystem, and its many freshwater ponds are a testament to the island’s rich natural heritage.

The Glass Float Project

Over the previous decade, there has been a unique development on Block Island related to its hiking trails. The practice, which has started as the result of the generosity of a local Rhode Island glass blower, involves the scattering of several hundred hand-blown glass orbs on the nearly 30 miles of hiking trails that are present on Block Island. Known as the Glass Float Project, what started as a way to connect and engage the local community with the outdoors has transformed into an activity that attracts outdoor enthusiasts far and wide who want to explore the island and seek out these beautiful works of art.

Mohegan Bluffs and Southeast Lighthouse

Staircase at Mohegan Bluffs, Block Island, RI

One of the most scenic destinations you’ll find anywhere, Mohegan Bluffs tower 200 feet above the Atlantic Ocean and offer a panoramic view of the surrounding landscape and shoreline. On a clear day, visitors can view Montauk out in the distance, the eastern tip of Long Island. The 141-step staircase leads down to one of the most secluded and beautiful beaches on Block Island. You can walk along the beach and explore the unique landscape for miles. While here, take some time to enjoy the historic Southeast Lighthouse as well. Over the years, the bluffs here have actually receded significantly, having eroded over 250 feet. As a result, the Lighthouse has been moved back about 360 feet from its original location to avoid it from collapsing into the ocean.
