Alan Davis (also: Allen Davis) - a rancher who's property was once in the area between Makapuu Lighthouse Road and Kalama Valley called Kaloko, now a popular off-road activities area. Most of the human-built features in the area, including the house, property, and ancient worship/cultural structures, were destroyed by a tidal wave in 1947. See Makapuu Tidepools Hike. (link)

army garrison - is now the 25th Infantry (Light) Division located at Schofield Barracks (Wahiawa) in central Oahu.

Castle Trail - two trails built under the leadership and funding of a single man around 1910. Both were produced as horse-riding trails and both are now extremely overgrown and highly dilapidated. The first Castle Trail, which intersects Waahila Ridge near the Koolau Crest, can be faintly seen on both sides while climbing the final ascent to Mount Olympus. Except for the occasional efforts of trail-clearing volunteers, the entire original Castle Trail is buried under vegetation and has been damaged by landslides. A few years later, the second Castle Trail was constructed from Punaluu Valley, across upper Kaluanui Valley and Stream, and to the V-notch along Waiahilahila Ridge. Later, a connector was constructed to meet the Koolau summit which later became a junction with the Koolau Summit Trail. See Castle-Punaluu Trail. (link)

Population-wise, Oahu is the largest island but it is not the biggest in terms of geographic size. Other inhabited islands include: Kauai, Molokai, Lanai, Maui, and Hawaii (Big Island). The seventh inhabited island, Niihau, is not accessible to the public as it is privately owned and houses a native Hawaiian society.

It is deep within military property, access is restricted, and is often patrolled by military police. The pass itself is the gateway between two military bases: Schofield Barracks (home to the U.S. Army 25th Infantry Light "Tropic Lightning" to the east and the Lualualei Naval Supply Magazine (home to the U.S. Navy's Pacific Fleet central-Pacific nuclear ammunition storage facility) to the west.

The scene involving the National Wildlife Service, where the Army officer points out where he wants to "truck" the radar equipment, was filmed at Kualoa and the peak he points out is the (inaccessible) Puu Kanehoalani. While there was a radar unit in this area at the time, the famed unit which detected the oncoming wave of Japanese planes (Which was dismissed as American bombers ferried from the U.S. mainland) was at Opana Point. There is a memorial monument and information plaques on the west side of the main hotel structure (near the beach) at Turtle Bay Resort.

Turtle Bay - a resort on Oahu's North Shore which sits on an ocean-front peninsula between Sunset Beach and Kahuku Point. The closest hiking area is Pupukea.

volcano - there are no active volcanoes on Oahu. Remnants of the two major shield volcanoes which produced Oahu stand on the west (Waianae Mountains) and east (Koolau Mountains) sides of the island. They virtually lean against each other forming the central Oahu plains (Wahiawa, Mililani, Kunia, Waipahu). The middle of the dormant Waianae caldera lies at Mauna Kuwale in Lualualei and the western side of the volcano has long since fallen into the ocean. The middle of the dormant Koolau caldera lies in Kawainui Marsh in Kailua - the eastern side of the volcano, too, has long since disappeared into the Pacific. For more information, see Roadside Geology of Hawaii.
