My name is ExtremeMan129. This is my concept of a natural, secret entrance in a mountain. This map will soon get part in some other projects of mine for the ultimate mountain house or/and hidden base. I maked the map so everyone could see it and if anyone could tell me a better or more compact design of my lava door. I don't have created a video/tutorial for it yet, but maybe in the nearby future i'll link it with this project, so anyone could make this entrance by themselves. I hope you will enjoy my idee. Have fun!
