This AI-assisted contemporary historical narrative by Clio Walker is based on the expedition journals. It is not an original submission or verbatim text by either captain. Personal observations, reported events, and editorial interpretation are distinguished by their evidence.

Lewis was delighted when he found the falls. On June 13, 1805, the wall of water confirmed that he and Clark had chosen the right river at the fork. When he went looking for somewhere to land the canoes, that satisfaction acquired another weight. The right river was not necessarily a river boats could ascend.

Downstream were further rapids and steep cliffs. Lewis went to investigate that afternoon and returned without a satisfactory landing route. Subsequent surveying showed that the obstacle was a succession of falls and rapids. The expedition could continue up the Missouri, but first its boats would have to leave it.

By mid-June the party was gathering at the lower portage camp. Sacagawea was seriously ill and her child still small. Hunters had to provide meat, the sick required attention, and the captains had to replace a water route with a land route. It could not be merely a path for lightly equipped walkers. Whole canoes, heavy stores, and transport equipment had to pass along it.

Clark surveyed the country. The heights of falls and extent of rapids mattered, but so did the means of climbing from the lower river onto the plain and descending again upstream. Ravines cut the apparently level country. Walking a straight line was one thing; arriving at a ravine with a canoe was another.

On June 20 Clark ordered stakes cut to mark the way for the transport party. At a ravine that could not carry the proposed traffic he spent time investigating a crossing. With the day advancing, he turned toward the river and returned with his measurements. The eventual portage was approximately eighteen miles. This was far more than a brief detour beside a single waterfall.

While waiting, Lewis prepared food. He sent hunters to the other bank, where broken ground made it easier to approach buffalo. They reported eleven killed, including animals in good condition. Everyone available went to fetch meat; a few stayed to finish the work. Lewis wanted a stock of dried meat before hauling began. Once men were moving boats, he did not want to keep diverting them to find dinner.

Such apparently ordinary work determined whether the expedition could move at all. Food did not follow automatically. Hunting, butchering, drying, and guarding carcasses had to enter the schedule before the wheels turned. Every pound of provisions increased the load while sustaining those who hauled it.

They made rough carriages, converting boats and baggage into loads that could travel over land. Wooden parts broke. Prickly pear pierced moccasins and injured feet, while wheels required continual attention. Terrain largely unnoticed during river travel now magnified every little slope and patch of wet ground.

The first journey exposed weaknesses in the timber. Cottonwood components and an axle made from an old mast had repeatedly failed before the party reached a stream where they stopped for dinner. They rebuilt axles and parts of the carriage with willow and resumed after about two hours. Skilled hands could work quickly; repairing a vehicle once did not end the damage.

After dark, only about half a mile from the intended camp, a tongue broke again. Hope would not carry the canoe the remaining distance. The men left it and shouldered as much baggage as they could take, continuing to the river. There they lit fires and inspected meat Clark had left. Wolves had consumed most of it. Reaching camp did not always mean that supper and rest could proceed as planned.

This first haul, begun on June 22, included parts of Lewis's iron-frame boat. By the following day the party had reached the upper camp near the White Bear Islands. The expedition was now divided by a land route. Some men repeatedly carried loads between its ends; others prepared a boat for the next stretch of river. The separate operations had to connect before they could once again become a traveling flotilla.

Lewis placed great hopes in the iron-frame craft. Its frame could be assembled and covered with hides, weighing less than a canoe hollowed from a substantial tree. If it worked, the expedition would gain carrying capacity without constantly needing to find large timber. They had transported its components a considerable distance. Now they needed the design to perform.

A frame was not a complete boat. Hides had to be joined, seams sealed, and a coating made to stay in place underwater. The prairie supplied hides but no convenient supply of suitable pitch. Lewis had to experiment with what was available. Each extra operation required more time, while builders, hunters, and haulers all continued to need feeding.

On June 27 Whitehouse was unwell. Lewis kept him from the portage party and set him to sewing hides with Frazier. Shields and Gass worked on wooden bars for the sections, but crooked and unsuitable timber slowed them. Lewis acted as cook so that other hands could remain at their tasks. His daily calculations concerned not only distance but who could walk, who could sew, and who would make dinner.

Hunters supplied more than food. Hides could cover the boat or protect baggage; fat entered both the provisions and experiments with sealant. On June 25 Drouillard and Frazier brought in a substantial stock of dried meat and tallow. The men sent for bark and wood that day returned with very little. Solving one shortage did not solve another. Both outcomes appear in the journal, showing a month assembled from operations that rarely advanced evenly.

The weather made no accommodation for the experiment. On June 29 wet ground hindered the loaded carriages, with mud collecting on wheels. Some men returned for baggage left the previous day. Clark went to replace lost survey notes, accompanied by York, Charbonneau, and Sacagawea.

Near the falls he saw a threatening cloud and sought shelter. He, Charbonneau, and Sacagawea entered a ravine with overhanging rock, placing guns and surveying equipment where they seemed protected from rain. York had separated to pursue game and had not seen them enter. Their shelter was also a channel for storm water.

Rain became a torrent carrying mud and stones. Sacagawea seized her child. Clark took his gun and shot pouch and climbed, pushing her upward; Charbonneau also pulled at her hand. They reached safety, but the child's carrier and clothing, together with equipment, were swept away. York returned looking for them, alarmed by their disappearance. These actions and fears come from Clark's account and Lewis's rendering of it, not a later dramatized escape scene.

The temporary camp offered little relief. The baggage party had been struck by hail. Men were knocked down, bruised, and bleeding, and had abandoned their loads. Streams rose and the plain was too wet for further work that evening. The captains could arrange labor, but could not issue orders to a storm.

There were occasional advantages too. The men reported using favorable wind to propel a canoe on its truck wheels, raising a sail to help the load across the land. A boat had left the river without entirely losing the use of its sail. This was an improvised opportunity, not a dependable transport system. When the wind changed, the weight and the road remained.

Lewis described men dropping down at each halt, some falling asleep almost immediately. Some limped with sore feet; others were temporarily unable to stand from heat and exhaustion. He also wrote that they did not complain. This was a captain observing and evaluating his men, not an independent account from every participant. Their accomplishment was nevertheless tangible. Without repeated labor moving loads across the plain, the captains' map would have remained only a map.

By July 2 supplies had reached the upper camp and the heaviest land transport was over. The expedition still could not depart. The new boat remained unfinished. A design intended to save effort was now consuming their remaining time.

On July 9 they launched the iron-frame boat. Lewis thought it rode extraordinarily lightly; five men could carry it easily. He ordered seats fitted and oars prepared. Other canoes were loaded for departure. Then a violent wind rose. Waves threatened the cargo, and baggage had to be unloaded once more.

By evening a second problem had become plain. Much of the sealing compound had separated from the skins, exposing the seams and allowing unacceptable leakage. Lewis noticed that buffalo-hide sections retaining short hair held the coating better than skins shaved too closely. He could still imagine improvements. He also understood that further trials were no longer practical. Buffalo had largely left the vicinity, the season was advancing, and the snowy mountains were no farther away.

He abandoned his favorite boat. It was not a demonstration that every possible version of the design must fail. They lacked pitch and time to continue experimenting. He ordered the boat sunk to soften its skins so that it could be dismantled the following day and the frame cached. Considerable labor had brought it there. Continuing the journey required accepting that past effort could not compel a leaking boat to work.

The lost capacity had to be replaced. The captains remembered hunters reporting larger trees upriver and agreed to build two more canoes. Clark would take ten capable workmen ahead. Lewis's remaining party would dismantle the boat, cache equipment, and move baggage in the six small canoes. That evening axes and adzes were sharpened for the next day's work.

A small grindstone carried from Harpers Ferry provided a more immediate service than the ambitious design. Lewis specifically mentioned its usefulness on this and earlier occasions. The ingenious frame would remain behind; the little stone continued helping them travel. Expeditions did not advance only through conspicuous inventions. Sometimes an ordinary tool mattered more.

By July 13 people and stores were being relocated to the new Canoe Camp. On July 15 the party resumed its ascent of the Missouri. More than a month had passed since Lewis first saw the falls. Days spent physically hauling were distinct from those devoted to surveying, experimental construction, and building replacement canoes; the whole interval should not be described as thirty uninterrupted days pulling carts.

When they loaded again, all eight boats were heavily burdened. Caches had reduced their stores, but the men had accumulated articles, and dried meat and fat occupied space. Lewis complained that keeping personal baggage within reasonable limits was difficult. At ten in the morning they finally got underway. He continued walking on shore to lighten the boats. Leaving the falls did not remove their burden. It allowed them to move forward with it.

The falls were behind them, but passing them had taken longer than finding them. Surveys, dried meat, route stakes, wheels, injured feet, and a dismantled iron frame had all contributed to departure. Ahead they would need Shoshone people and horses. Before reaching them, they had already learned a demanding lesson: a boat that floated on a river could not necessarily carry its passengers across a continent.
