The cave galleries have a typical width of 40 meters and can reach up to 60 meters in places where the floor is covered with huge breakdown, some the size of buildings. The biggest space found in the cave has been Gran Galería Karen y Fanny, with a dome to 40 meters height and measuring more than 355 meters long.Other spectacular CCB pictures can be seen here. The cave is named after its discoverer, Charles Brewer-Carías, a controversial Venezuelan explorer and Doyle look-alike (who also took the helicopter cave shot.)
As the walls are 70 meters apart, the volume of this area has been estimated in 400,000 m3. (The second largest space is 320,000 m3 at the Gran Galería de los Guácharos, near the entrance.) The rest of the great spaces inside the cave consists of canyons where the smallest profiles reaches 15 x 20 meters. These passages are very dynamic in terms of water movement and is where beautiful waterfalls and rapids are found. Due to this fact, these are the most hazardous segments of the cave.
One of the most interesting features of the main gallery is its straightness, showing few bends or parallel galleries. The general disposition of the cave is that of being parallel to the top of the mountain and running 150 to 200 meters below the surface. Inside the cave, there are some red mud terraces, beatiful sandy beaches with ripple-marked sand, small marmits filled with quartz-polished lentils, some clean walls and others ridged with lateral ledges, columns, and rock bridges.
