Camp Disappointment is the northernmost point reached by the Lewis and Clark Expedition. They reached here on July 23, 1806.
On the Cut Bank River east of present-day Browning, Lewis could see the river exiting the mountains. He called this northern-most campsite of the expedition 'Camp Disappointment' since this meant the Marias did not reach 50 degrees north latitude, which would have extended the boundary of the Louisiana Territory. At milepost 233 on US 2, there is a historical highway marker which is four miles directly south of the actual camp site.
