The maximum frost depth observed in the contiguous United States ranges from 0 to 8 feet (2.4 m). [1] Below that depth, the temperature varies, but is always above 0 °C (32 °F). Alternatively, in Arctic and Antarctic locations the freezing depth is so deep that it becomes year-round permafrost, and the term "thaw depth" is used
East Los Angeles, the Gateway Cities, and parts of the San Gabriel Valley average the warmest winter high temps (72 °F, 22 °C) in all of the western U.S., and Santa Monica averages the warmest winter lows (52 °F, 11 °C) in all of the western U.S. Palm Springs, a city in the Coachella Valley, averages high/low/mean temperatures of 75 °F/50 ...
The State Mining Bureau was renamed the Division of Mines and Geology in 1862. Its pseudonym, the California Geologic Survey, was established in January 2002. [15] In 1869, George Davidson, an assistant coast surveyor, compiled the book Pacific Coast: Coast Pilot of California, Oregon, and Washington Territory. The 262-page volume is complete ...
Most in one calendar month: 9.91 meters (390 inches) of snow fell in Tamarack, California, in January 1911, leading to a snow depth in March of 11.46 meters (451 inches) (greatest measured in North America). [307] [308] Most in one season (1 July – 30 June): 29.0 meters, (95 ft); Mount Baker, Washington, United States, 1998 through 1999. [307]
In construction, the thaw depth is a major factor in ensuring the structural integrity of the objects in question. The primary factor that determines the thaw depth is the maximal air temperature. The soil type is another important factor: coarser textures of the parent material have higher thermal conductivity , and, e.g., sandy soils have ...
The 1562 map of the Americas, created by Spanish cartographer Diego Gutiérrez, which applied the name California for the first time.. California was the name given to a mythical island populated only by beautiful Amazon warriors, as depicted in Greek myths, using gold tools and weapons in the popular early 16th-century romance novel Las Sergas de Esplandián (The Adventures of Esplandián) by ...

Since official records were first kept in 1877, the downtown Los Angeles weather station observed measurable snowfall three times, in 1882, 1932, and 1949.
