Clark: March 21, 1805
On a cloudy, snowy Thursday, the men hauled the last two canoes down to the river, leaving three behind to finish the work, and returned to the fort with their baggage. Heading back to the fort, Clark crossed high hills covered with large quantities of pumice stone and burnt earth, signs the hills had once been on fire. He gathered samples and tested them in a furnace, finding the hard clay melted into a glaze and itself became pumice. He also collected a plant whose root reportedly cures mad dog and snake bites, intending to send it to Mr. Haney.
I return on the 21st and on my return I passed on the points of the high
hills S. S. where I saw an emence quantity of Pumice Stone, and evident

I returned on the 21st, and on my return I passed over the points of the high hills S. S., where I saw an immense quantity of pumice stone, and evident marks of the hills having been on fire. I collected some pumice stone, burnt stone, and hard earth, and put them into a furnace. The hard earth melted and glazed the other two, a part of which (i.e., the hard clay) became a pumice stone. I also collected a plant, the root of which is a cure for the bite of a mad dog and snake, which I shall send Mr. Haney (I think it grows in the Blue R. Barrens). The Indians make large beads of different colors.
