Mount Shasta in northern California is known as a hotbed of strange events, from Big Foot sightings to UFO encounters to hikers vanishing without a trace. Some people in Mount Shasta believe that a lost continent called Lemuria is hidden beneath the mountain, along with its capital crystalline city, Telos. Could the mountain's unique geology and placement on Earth be attracting beings from other worlds - and even other dimensions?
