The iconic islands of Oahu and Kauai, known for their stunning beauty, were once much taller than they are today. Millions of years of erosion have sculpted these islands, gradually wearing them down to their current size. Discovering the ancient remnants of these once towering islands adds another layer of fascination to Hawaii’s geological history.
6. First Humans to Visit – Polynesians from Marquesas Islands
Before Hawaii became the paradise we know it as today, it was first visited and settled by Polynesians from the Marquesas Islands. These intrepid explorers journeyed across vast stretches of open ocean, eventually making their way to the Hawaiian Islands. Their arrival marked the beginning of a rich cultural heritage that still resonates today.
7. Caste System Established by Early Settlers
The earliest settlers who established themselves in Hawaii also established a caste system, categorizing individuals based on their ancestry and social status. This social structure played a significant role in shaping the early Hawaiian society and influenced their interactions with the volcanic landscape.
8. Buffalo Soldiers in Hawaii Volcanoes National Park
In what is now known as Hawaii Volcanoes National Park, Buffalo Soldiers, African-American regiments of the United States Army, were stationed in the late 1800s. These soldiers played a vital role in protecting the park’s natural and cultural resources, leaving a unique mark in the volcanic history of Hawaii.
9. Mark Twain’s Journey to Kilauea
Renowned author Mark Twain embarked on a journey to the awe-inspiring Kilauea volcano in the late 1800s. His vivid descriptions of the volcanic landscape and his experiences amidst the fiery fury of an erupting volcano have forever immortalized Kilauea in literary history.
10. A Historic Landmark Over 150 Years Old
