On July 16, 1805, some ten miles south of today's Cascade, Montana, Lewis experienced a new gustatory delight.

Drewyer killed a buffaloe this morning near the river and we halted and breakfasted on it. here for the first time I ate of the small guts of the buffaloe cooked over a blazing fire in the Indian style, without any preperation of washing or other clensing, and found them very good.
