Epsom Salts Monorail however, is inside the Death Valley National Park and accessible via the Fort Irwin Army Base near Tecopa. The sidings of the Trona Railway can be reached by an unsurfaced track from California Highway 178. If carriages are parked on the sidings, these are easy to spot. There are some concrete foundations and ruins of houses in the area. Epsom Salts Monorail The Epsom Salts Monorail or Magnesium Monorail was a short-lived Lartigue Monorail in San Bernardino County, California, in the United States. It was built to carry epsomite (hydrated magnesium sulphate) from a deposit in the Owlshead Mountains to
Magnesium oxychloride dioxide from the air to form magnesium chlorocarbonates. Anhydrous and partially hydrated forms also absorb water, turning into phase 5 and then phase 3 on the way to the chlorocarbonate. The exceptions are the dihydrate and hexahydrate of phase 9, that remain unchanged for many months. The crystal structure of phase 3 is triclinic with space group formula_1 and "z" = 2. The solid consists polymeric aquohydroxo cations, in the form of double chains of magnesium atoms surrounded and bridged by the oxygen atoms in hydroxy groups and complexed water molecules. These linear cations are interleaved and neutralized by chloride
