Summer makes for some epic thunderstorms. Case in point: this dramatic pic of a lighting strike at Badlands National Park in South Dakota from earlier in August. Photo by Badlands’ Seasonal Park Paleontologist Phil Varela, National Park Service. Tweeted by the US Department of the Interior, 9/2/16.
In this rare sight, a rainbow (some call it a “blob-bow”) brightens the dunes following an afternoon storm at Great Sand Dunes National Park and Preserve in Colorado. Summer thunderstorms at the park are common and bring cool winds, heavy rain and lightning. When storms approach, be sure to come down off the dunes, as lightning often strikes the dunefield. The electrical current fuses or melts sand particles together, resulting in a “fulgurite” (Latin for lightning rock). Photo by Patrick Myers, National Park Service.
