| West of the Great Plains, are the massive, rugged Rocky Mountain system of the US and Canada. The Rockies are a series of ranges that extend about 3000 miles from Alaska south to New Mexico. Because they are relatively young - about 80 million years old - the Rockies have not been eroded like the Appalachians. Many of their jagged, snow-covered peaks are more than 12,000 feet high. Can you tell me what the 14ers are? |
