Highest point on Roraima

Hiking in the rain to the highest point at 9219'. There was no view of the 2000' sheer drop to the jungle below due to the clouds. The soil of the tepui is made mainly of quartzite deposited 1.7 billion years ago (Precambrian). This is one of the Earth's oldest rocks. Over many years, water dissolved sand particles in the stone blocks, which result in odd rock formations (sort of like ruined sand castles or small towers). The rocks are blackened by likens. Red color just added for fun.
