We’ve come across these mounds of shells on the beaches of Bear Lake. You can bury your feet in them and I’ve learned they have an interesting history.
“Many ancient clam and snail shells have been found around the shoreline of Bear
Lake. Local residents have at times gathered the shells as a source of calcium for
their chickens. These shells are well preserved and have been dated to be 10,000
years old (Smart, 1963). Curators at the Smithsonian Institute identified all 6
species of snail and one species of clam. Carbon dating performed by Columbia
University estimated shells gathered from the Ideal Beach area of Bear Lake to be
12,000 years old.”
