Rockhounding seminar at Sumner Library Friday

What is rockhounding? It's the hunt for interesting and collectible geologic formations. Rockhounders venture out into the wild — or at least their backyard — armed with knowledge and a few tools to find notable rocks, gemstones, minerals and fossils.

Sumner Library will host a seminar on rockhounding for adults and children older than 7 on Friday at 3:30 p.m.

What is rockhounding? It’s the hunt for interesting and collectible geologic formations. Rockhounders venture out into the wild — or at least their backyard — armed with knowledge and a few tools to find notable rocks, gemstones, minerals and fossils.

Gator Girl Rocks, a website that bills itself as America’s Best Rockhounding Resource, notes that Washington state’s volcanoes and glaciers make it a rich playing field for ‘hounders.

The Sumner Library seminar will teach beginners which rocks are keepers, where to find them and what tools to use to harvest them from the ground.

Registration for the event is required to attend. Call 253-548-3306 for more information.

Geology is prominent in the theme of the Pierce County Library System’s Summer 2013 reading program, which began Saturday. Libraries in the system are holding events for children 3- to 11-years-old focusing on fossils, composting, burrowing animals and off-road adventures. Some of the prizes for reading include free passes to Point Defiance Zoo and Northwest Trek.

For teens, the libraries will continue their “online game” reading program. Participants will be able to earn badges and achievements for pages read, and discount existing library fines where applicable. The top point earners will be entered into a drawing for an iPad donated by the Pierce County Library Foundation.
