Guide to the Diamond Head Monument Observation Deck
Most people that hike the Diamond Head trail are not familiar with the history behind it. The monument was originally known as Leahi until a few British sailors came to Oahu in 1898. The British sailors thought that the crater has many diamonds because of the sparkles that it gives out. They discovered that the sparkles are actually from the calcite crystals that are hidden in the lava rock.
Diamond Head was converted into a defense station in 1898. A canon with 12 inches of mortars was set up in the Diamond Head crater. The canon has the ability to fire the projectile at up to 11 miles. The army installed in the canon at the Diamond Head crater because no one can find it there easily. The downside of setting up the canon at Diamond Head crater is that it is hard for the army to observe the target. At that time, the radar did not existed yet. The people track their enemies by using telescope. When the army found the enemy, they will report the position to the battery through telephone.
If you go to Diamond Head crater, you will find an observation deck. The observation deck at Diamond Head was built in 1908. The people use shovel to dig the ground when building the observation deck. Cables are used to raise the construction material to the workers. After some time, they manage to build an observation deck with 4 level of observation deck. The levels of the Diamond Head observation deck are connected with staircases. The observation deck was built under the instruction of William H. Taft. Taft wanted to protect the Pearl Harbor from the enemies so he decided to build the observation deck. Taft was chosen as the 27th American president later.
Besides the observation deck, the people dug a tunnel in the crater wall so that they can easily gain access to the observation deck. Radar was installed at the observation deck later. Later, the observation deck becomes abandoned. You can still see the remains of the observation deck at the Diamond Head Crater. The trail that leads to the summit of the Diamond Head crater is steep. You have to climb several staircases to reach the top of the Diamond Head crater. When traveling to the crater, be sure to bring enough drinking water. You should also bring along torchlight so that you can see clearly.
