One island in Hawaii that is so famous and familiar to us all is the Island of Maui. Over the millennia Maui's geography has changed even more drastically. Formed by six different volcanoes, the islands of Maui, Moloka'i, Lana'i and Kaho'olawe were once a single landmass known as Maui Nui ("Great Maui"). Rising sea levels eventually separated the islands, though they are still legally linked today � all are part of Maui County. This varied landscape has led to an equally varied society: The central Maui town of Kahului/Wailuku is the island's business center; West Maui, with the sprawling beaches and upscale hotels of Ka'anapali and the historic whaling town of Lahaina, is one of Maui's major resort areas. South Maui is home to the island's other main resort district, Wailea; and while the tropical north shore of Maui does not offer hotels, visitors can choose from a collection of bed & breakfasts and rental homes. The second largest of the populated Hawaiian Islands, Maui also boasts the second-largest population in the state, behind O'ahu (120,785 in 1998). Haleakala, whose name translates as "house of the sun," is the largest dormant volcano in the world. Not yet extinct, it is expected to erupt sometime in the next 200 years (it last erupted in 1790). The underwater valleys that once connected Maui, Moloka'i Lana'i and Kaho'olawe are shallower than the surrounding ocean, providing shelter for an abundance of marine life � including the humpback whales that migrate to Hawaiian waters during winter months to give birth to their calves. Temperatures on Maui range from 70 to 80 degrees Fahrenheit year-round, although the slopes of Haleakala Crater often see lows of 40 degrees. The lowest recorded temperature on Haleakala was 14 degrees Fahrenheit. Maui's official flower is the loke lani (pink cottage rose). Maui's official color is pink.
