EDMONDS, Wash. -- After untold millennia of glacier surfing, a big rock in Edmonds, Wash., is taking a quick, 12,000-year break.
  
Geologists believe a boulder located in a mobile-home park is an "erratic," a stone deposited in the area by glaciers during the ice age.
  
The rock is roughly 12 feet high by 10 feet wide by 15 feet long.
  
Dave Tucker, a research associate in geology at Western Washington University, tells The Herald newspaper the boulder in Edmonds is about the size of a camper.
  
Tucker discusses the boulder, and others, on his website, titled Northwest Geology Field Trips.
  
A geology professor emeritus at Shoreline Community College says many erratics are located around the Puget Sound area, from some as big as a house to beach-ball-sized stones buried in our back yards.
