Standing on the wooded slopes of West Elizabeth in Big Valley, north west of lake Owanjila stands an obelisk monument. It is a three sided stone obelisk set on top a stone plinth, approximately 18 feet (5.5 metres) in height. The stone is weathered implying age and partly moss covered. It's original purpose is unknown.
An engraved metal plaque is attached to the western side, which can be interacted with to obtain the map piece. The plaque consists a simple Latin text and a date; 'Hora fugit, ne tardes 1771'.
- The form of the obelisk was changed slightly after the PC version of the game was launched (November 2019) and a treasure map was added. This utilises the obelisk for the first maps location. Originally the stone plinth was stepped but with the change it is now straight edged. A few shrubs were also removed around the base. At this time an engraved metal plaque was added to the west side.
- The first map of the Landmarks of Riches Map is located on the Obelisk.
- The plaques motto has been used on actual historic sundials and means 'the hour flees, don't be late'. This possibly implies that it could be used like one, with its shadow cast like from a gnomon on a sundial.
- When either Arthur or John draws the obelisk in their journal it reflects the original stepped plinth design, not the later form the player sees now.
- A broken version of the Obelisk model can be found in three locations of Cayo Perico in Grand Theft Auto Online, one in the airstrip, one in a small island and another in a graveyard, where its pieces are used as tombstones. The engraved metal plaque is absent in all of the three obelisks in GTA Online.
