This obelisk/sundial can be found in the southwest corner of White Point Garden. It commemorates one of the worst naval disasters in US history — the collision of the USS Hobson (a destroyer) with the much larger USS Wasp (an aircraft carrier) The Hobson was essential cut in two — killing 176 sailors. The Charleston connection is that the Hobson, was built in the North Charleston Naval Yard and had also been based in Charleston. The stones around the monument were brought in from the 38 home states of the men who died.
