Marker text: CAMP DISAPPOINTMENT
The monument on the hill above was erected by the Great Northern Railway in 1925 to commemorate the farthest point north reached by the Lewis and Clark Expedition, 1804-06. Captain Meriwether Lewis, with three of his best men left the main party at the Missouri River and embarked on a side trip to explore the headwaters of the Marias River. He hoped to be able to report to President Jefferson that the headwaters arose north of the 49th parallel, thus extending the boundaries of the newly acquired Louisiana Purchase.
