These rocks had been identified as lava because the unit has a high aspect ratio () and very high viscosity of the crystal-rich magma similar to those of flow-layered silicic lava.However, the Pagosa Peak Dacite formed by low-column pyroclastic fountaining and lateral transport as dense, poorly-inflated pyroclastic flows.There are also large intracaldera lavas composed of andesite, a volcanic rock compositionally intermediate between basalt (poor in silica content) and dacite (higher silica content) in the La Garita Caldera.The caldera itself, like the eruption of Fish Canyon Tuff, is quite large in scale.
When Mu sank and the mountains were raised, man degenerated into the savagery out of which our own civilization emerged."Before the shock waves had settled, the Colonel followed quickly with his companion editions, The Children of Mu (1931), The Sacred Symbols of Mu (1933), and Cosmic Forces of Mu in two parts, 1934-35.Because of the vast scale and erosion, it took scientists over 30 years to fully determine the size of the caldera. La Garita is also the source of at least 7 major eruptions of welded tuff deposits over a span of 1.5 million years since the Fish Canyon Tuff eruption.The caldera is also known to have extensive outcrops of a very unusual lava-like rock unit, called the Pagosa Peak Dacite, made of dacite that is very similar to that of the Fish Canyon Tuff.only two years prior to the Colonels first work, John Mac Millan Brown, a retired professor at Canterbury University College, introduced his Riddle of the Pacific, claiming there was once a continent in the Pacific, now submerged save for island groups, on which megalithic ruins still existed.
The etymology is confusing at best: Lemuria allegedly received its name first though English naturalist Philip Lutley Schlater who dubbed it that in 1870 to designate the land-route lemurs used to spread from Madagascar to New Guinea, in his Geography of Mammals (London, 1889). A more likely scenario is that the name derived from ancient Romans use of the word "Lentures" to describe spirits of their dead ancestors., in his trance readings on Lemuria in the 1930s, refers to it as "Muri, or Lemuria," as well as "La-Mu," "Mu" and "Zu." It is called "Ra-Mu" in the Lhasa Records, 4.000-year-old Tibetan texts written in Chaldean, discovered by Paul Schliemann (grandson of Heinrich, who unearthed Troy) in a Buddhist temple.important points of pre-history and anthropology he had compiled through more than 50 years of research and exploration throughout Asia and the South Sea:"There was once a flourishing continent in the middle of the Pacific Ocean called Mu ...
