The result is that the island is constantly warmer and more humid than the outside area, and is constantly enshrouded by mist. This has helped disguise the island from passing ships and satellite photographs, and allowed it to go unnoticed since before recorded history. The island is divided in two by a small range of rocky crags including 2 active volcanoes. The northwest portion of the island is plains edged with forest. It is here that most of the large dinosaurs live.
Primitive humans live in caves here along the edge of the mountains.
The southeast portion of the island is mainly jungle. There are a variety of dangerous predatory mammals and dinosaurs here. There is a lodge dwelling here on the southern bay. It is the laboratory of a human doctor who washed up on the shores 20 years ago. The two volcano cones on the island are active but rarely erupt, and only to send a few streams of molten rock down the sides of the mountain.
