My travels recently took me to beautiful Lake Toba. Here's a glimpse: "Lake Toba (Indonesian: Danau Toba) is a lake and supervolcano, 62.5 miles long and 20 miles wide, and 1,666 ft at its deepest point. Located in the middle of the northern part of the Indonesian island of Sumatra with a surface elevation of about 2,953 ft, it is the largest volcanic lake in the world. In addition, it is the site of a supervolcanic eruption that occurred 74,000 years ago, a massive climate-changing event. The eruption is believed to have a VEI intensity of 8. This eruption, believed to have been the largest anywhere on Earth in the last 25 million years, may have had catastrophic consequences globally; some anthropologists and archaeologists believe that it killed most humans then alive, creating a population bottleneck in Central Eastern Africa and India that affected the genetic inheritance of all humans today." (according to Wikipedia)
This picture was taken from an island in the middle of Lake Toba. That's right, we were on an island in a lake that is on an island in the ocean.
