Inscription. Look slightly to your left at the end of Fort Peck Lake to find the highest hill in this area, today called Signal Hill. It was near this area that Captain William Clark first viewed and named the Milk River as it enters the Missouri River. Lewis and Clark concluded correctly that this was the same river the Hidatsa Indians at Fort Mandan referred to as the "River Which Scolds at All Others". Imagine how like an oasis in the middle of the prairie these two converging rivers must have seemed!

"The water of this river possesses a peculiar whiteness, being about the colour of a cup of tea with the admixture of a tablespoonfull of milk. from the colour of it's water we called it Milk river...Capt Clark who walked this morning on the Lard. shore ascended a very highpoint opposite to the mouth of the river; he informed me that he had a perfect view of this river and the country through which it passed... –Captain M. Lewis, Wednesday May 8, 1805

Scientific Discovery: White Apple, (Psoralea esculenta) (Indian Bread Root)
"The white apple is found in great abundance in this neighbourhood... our epicures would admire this root very much, it would serve them in their ragouts and gravies in stead of the truffles morella."
