Are there any volcanic bombs at Craters of the Moon?


Yes, 4 kinds of bombs, all of which start off as globs of molten rock that were thrown into the air. If the glob gets twisted during its flight it is called a spindle bomb and is typically from a few inches to several feet in length. If it is very tiny and twisted it is called a ribbon bomb. If a glob forms a crust as it flies through the air and the gasses inside continue to expand and crack that crust, like bread that continues rise in the oven, it is called a breadcrust bomb. If the glob didn’t completely solidify during flight, so that it went splat and flattened on landing, it is called a cow-pie bomb. Some of the cow-pie bombs are over 10-ft. long.
