IDAHO FALLS, Idaho (AP) — Officials with Craters of the Moon National Monument and Preserve have a new tool to help visitors: A smartphone app that identifies 100 of the most common plants and wildflowers found at the Idaho park.

Ted Stout with the monument's outreach program told the Post Register  that this summer is the first time the park has made the technology available to visitors. He says visitors can download the free app to their Apple or Android devices, and use it to search for plants by color, shape and other characteristics.

Stout says June brings the most impressive show of flowers at the monument, with Dwarf monkey flower, buckwheat and silverleaf phacelia already dotting the park's cinder cones. The application can be downloaded from the National Park Service website.
