In my last post I pointed out a possible mountain in the midst of a depression on Pluto's moon Charron. We can come closer to home, however, to see the same phenomenon. Crater Lake in Oregon has a similar feature. Crater Lake is a caldera which is a lake formed after a volcanic eruption. If the top of the volcanic mountain is destroyed, a depression can be formed and water can fill it. In the case of Crater Lake a mountain also developed in the midst of the lake. The mountain is called Wizard Mountain.
The mountain in my book is named Mount Milnak by the people that live within and below it. They depend on that mountain to keep them protected by the rapidly changing surface of their planet and use it as a launching bay for their small ships. Unfortunately for them, the Kevutians have just discovered their mountain but do not yet know it is inhabited. Kevutians believe they are the only beings in the universe and that the universe was made for them exclusively. They are about to find out that they were very wrong in their assumption.
