Source and derivation of name
The two words of the name of "Lodge Grass" are not usually put together, in that order, to make a commonly used name, or meaningful phrase. This is because the name "Lodge Grass" came from a mistake of interpretation of the Crow Indian name for "Greasy Grass".
Lodge Grass is named after Lodge Grass Creek, which flows through the town, but as explained in a video viewed in 2013 on YouTube by Joe Medicine Crow, Crow tribal historian, the correct Crow name for Lodge Grass Creek is Greasy Grass Creek.
Crow tradition holds that when the Crows camped on the bottoms of the Lodge Grass Creek or the Little Bighorn River in the spring and summer, when the grass in the valley would be high and when the dew was heavy the bellies and legs of the horses would become wet and glisten as if covered with grease.
A traditional camping area near the town is called in the Crow language.
