a small concrete cairn marks the point at which the Brazilian, Venezuelan, and Guyanese borders meet. The point is long three-hour hike from the entry point to the summit. The valley of the crystals is close by, an area of exposed quartz veins.
Mount Roraima is the highest of the Pacaraima chain of tepuis or plateaux in South America. It is located at the junction of Brazil, Guyana and Venezuela. A characteristic, large, flat-topped mountain surrounded by cliffs 400–1,000 m (1,300–3,300 ft) high, its highest point is located on the southern edge of the cliff at an elevation of 2,810 m (9,220 ft) in Venezuela. Another protrusion at an elevation of 2,772 m (9,094 ft) at the junction of the three countries in the north of the plateau is the highest point in Guyana. The name Mount Roraima came from the native Pemon people. Roroi in the Pemon language means "blue-green", and ma means "great".
