The Sierra Nevada Mountains

The other day, I came across an article that talked about the huge mountain range that stretch from Northern California all the way to Nevada which is popuparly called as the Sierra-Nevada Mountains. Since my husband have been living here in Amador County which is part of the Sierra-Nevada Mountain, I asked him if he knew what Sierra-Nevada Mountain means, he was not so sure, so I thought that there are probably more people living here in the slopes of the Sierra-Nevada mountains but not quite sure what the words Sierra-Nevada Mountain means. According to my reading, Sierra-Nevada Mountains means Snow-Covered Mountains, which for many years been true to its named since the mountain range regularly get plenty of snowfall year after year.
