1,900 feet long, 700 feet wide, 128 feet high - The rock derived its name from a party of fur trappers who camped there and celebrated Independence Day in their own style on July 4, 1830. Independence Rock became one of the great bulletin boards of the Oregon-California Trail-a place to look for word of friends ahead or leave messages for those coming behind.  -  source of info
