CONTRIBUTED — Join Senior Services at Memorial Park Community Center, 510 Bert St., Johnson City, for an eight-week video lecture series featuring a long list of natural wonders and fascinating geological attractions.

Yellowstone, the Grand Canyon, Mount Fuji, and the Galapagos Islands appear on many people’s list of spectacular must-see attractions but many other wonders, such as Ha Long Bay, the Columbia Glacier, Erta Ale’s lava lake and the Great Blue Hole also belong on the list. These and more than 200 other sites, both famous and obscure, offer breathtaking vistas well worth the visit.

The free series is open to all ages and will be held from 10-11 a.m. on Fridays, Jan. 10-Feb.
