OAKLAND — Paul Johnson, or Oakland and a former Maine state biologist, will present a virtual tour of Yellowstone National Park at 2 p.m. Wednesday, Sept. 14.
Yellowstone National Park is the oldest national park in the world. Centered over the Yellowstone Caldera, the largest caldera in the country, its volcano is considered dormant but it still supplies half the world’s geysers. The park is also the home of hundreds of species of animals. Grizzlies, black bears, wolves, bison and elk are the largest examples.
Issues affecting the park include global warming, invasive plants and animals, hydrothermal explosions and hot springs, large earthquakes, weather changes, contact with large animals and fatal falls.
The event is free and open to the public. For more information, call 207-465-7533.
