The Calico Early Man Site includes: * Artifacts of the Lake Manix Lithic Industry (LMLI) found on and just below the surface at elevations greater than , the shoreline elevation of a freshwater Pleistocene lake which emptied approximately 18,000 years ago. * Material recovered from nested Pleistocene alluvial deposits stratigraphically beneath a 100,000-year-old soil profile: a 'rock ring' (not a fire hearth) dated to 135,000 years by therm ...

Today, Yermo is governed by an elected five-member board of directors comprising the Community Services District authorized by the County of San Bernardino.

Yermo's ZIP Code is 92398, and it is in telephone area codes 442 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
