Mauna Kea
Mauna Kea ( or , ) is a dormant volcano on the island of Hawaii. Its peak is above sea level, making it the highest point in the state of Hawaii. Most of the mountain is under water, and when measured from its oceanic base, Mauna Kea is the tallest mountain in the world measuring over . Mauna Kea is about a million years old, and has thus passed the most active shield stage of life hundreds of thousands of years ago. In its current post-shield state, its lava is more viscous, resulting in a steeper profile. Late volcanism has also given it a much rougher appearance than its neighboring volcanoes due to construction of cinder cones, decentralization of its rift zones, glaciation on its peak, and weathering by the prevailing trade winds. Mauna Kea last erupted 6,000 to 4,000 years ago and is now considered dormant. The peak is only about higher than its more massive neighbor, Mauna Loa.
Aloha Tower
The Aloha Tower is a lighthouse that is considered one of the landmarks of the state of Hawaii in the United States. Opened on September 11, 1926 at a then astronomical cost of $160,000, the Aloha Tower is located at Pier 9 of Honolulu Harbor. It has been, and continues to be, a guiding beacon welcoming vessels to the City and County of Honolulu. Just as the Statue of Liberty greeted hundreds of thousands of immigrants each year to New York City, the Aloha Tower greeted hundreds of thousands of immigrants to Honolulu. At 10 stories and 184 feet (56 m) of height topped with 40 feet (12 m) of flag mast, for four decades the Aloha Tower was the tallest structure in Hawaii. It was built in the Hawaiian Gothic architectural style.
