Big boulder in Edmonds one of many left by long-gone glaciers
The (Everett) Herald
After untold millennia of glacier surfing, this big rock is taking a quick, 12,000-year break. Geologists believe a boulder located in a mobile-home park just off Edmonds Way is an "erratic," a stone deposited in the area by glaciers during the ice age. Looking at the rock -- roughly 12 feet high by 10 feet wide by 15 feet long -- "erratic" would seem to be a misnomer.
