Full list of words from this list:

  1. remnant
    a small part remaining after the main part no longer exists
    The vines were remnants of a handrail from a footbridge that the rising waters had washed away.
  2. undergrowth
    the brush beneath taller trees in a wood or forest
    With no choice but to stop, the camaradas began setting up camp. Meanwhile, Rondon and the rest of the men cut through the undergrowth along the river’s edge to determine how far the rapids went.
  3. intersperse
    place between or among
    For nearly a mile, the rapids swept on, interspersed along the way with a number of waterfalls.
  4. portage
    overland track between navigable waterways
    They knew that their sole choice now was to build a portage, or overland route, so they could drag their canoes to the point where the rapids ended. This was not an easy undertaking, and it would take days to build the trail.
  5. undertaking
    any piece of work that is attempted
    They knew that their sole choice now was to build a portage, or overland route, so they could drag their canoes to the point where the rapids ended. This was not an easy undertaking, and it would take days to build the trail.
  6. makeshift
    done or made using whatever is available
    The tree trunks acted as rollers, allowing a man to harness the canoe to his body with a rope and pull—like a horse pulling a wagon while another man stood behind it with a pole and pushed and prodded the canoe as it moved sluggishly over the makeshift “road.”
  7. profusely
    in very large amounts or quantities; extremely
    The effectiveness of the fly dope ointment wore off after about a half hour—partly because they were sweating profusely from the intense heat.
  8. incessant
    uninterrupted in time and indefinitely long continuing
    "It not only cost two and a half days of severe and incessant labor, but it cost something in the damage to the canoes,” Roosevelt stated.
  9. ominous
    threatening or foreshadowing evil or tragic developments
    At three o’clock that afternoon, the current suddenly picked up its pace, and the men again heard the ominous roar of rapids.
  10. impassable
    incapable of being gone across or through
    Four grueling days later, the canoes were back on the river. But the expedition traveled only one mile before reaching another set of impassable rapids. Disheartened, the men moored their canoes securely to some trees and set up camp.
  11. disheartened
    made less hopeful or enthusiastic
    Four grueling days later, the canoes were back on the river. But the expedition traveled only one mile before reaching another set of impassable rapids. Disheartened, the men moored their canoes securely to some trees and set up camp.
  12. moor
    secure with cables or ropes
    Four grueling days later, the canoes were back on the river. But the expedition traveled only one mile before reaching another set of impassable rapids. Disheartened, the men moored their canoes securely to some trees and set up camp.
  13. pulverize
    destroy completely
    Roosevelt figured that the rising river caused the leaky canoe to sink, pulling the canoe it was tied to under as well. Once the canoes were sunk, the water yanked and pulled them free from their moors. The canoes were then swept away, crashing into rocks that pulverized them to bits.
  14. morale
    a state of individual psychological well-being
    There was no doubt that morale was low.
  15. tedious
    so lacking in interest as to cause mental weariness
    Building a new canoe was backbreaking, tedious work that cost the expedition precious time.
  16. tributary
    a branch that flows into the main stream
    If it turned out that the River of Doubt was a tributary of the Amazon River, they estimated that they had to travel another four hundred miles.
  17. prevalent
    most frequent or common
    Malaria was the most feared and the most prevalent disease in the Amazon.
  18. convulsion
    a violent uncontrollable contraction of muscles
    The first signs of malaria include a teeth-chattering chill along with a pounding headache, followed by a dangerously high fever, and then profuse sweating. At this point, the victim is usually extremely exhausted and weak, and can do nothing but sleep. This is followed by vomiting, diarrhea, convulsions, and in some cases if left untreated, kidney failure, seizures, confusion, and death.
  19. quinine
    a bitter extract from cinchona bark, used to treat malaria
    At the time, the only medicine to combat malaria was quinine, which is extracted from the bark of the cinchona tree.
  20. obligated
    caused by law or conscience to follow a certain course
    João and Simplicio didn’t want to disobey Rondon’s order to stay put, but they didn’t want to disobey Kermit’s order, either. Feeling obligated, they started paddling the canoe downstream toward the island.
  21. fatigue
    temporary loss of strength and energy from hard work
    Knowing it was his best and, most likely, only chance to save himself, he reached up. His arm burned with fatigue as his wet hand seized the branch. With his last bit of strength, Kermit pulled himself out of the water and climbed onto the river’s muddy edge.
  22. speculate
    believe, especially on uncertain or tentative grounds
    The men speculated that when he went over the waterfall, his body must have been pulled underwater and beaten against the boulders, drowning him.
  23. unanimous
    in complete agreement
    Since first spotting the expedition members, the Cinta Larga had been holding tribal meetings, trying to decide if they should go to war and kill the invaders. Since they weren’t governed by a chief, the decision had to be unanimous.
  24. goodwill
    a disposition to kindness and compassion
    Despite the fact that the Cinta Larga had attacked and killed his beloved dog, Rondon left the tribe some beads and metal axes in an effort to keep the peace. Even so, Rondon and the others knew that this gesture of goodwill was no guarantee that the Cinta Larga wouldn’t attack.
  25. grim
    causing dejection
    There was no denying that their situation was looking grim.
  26. behoove
    be appropriate or necessary
    “So far the country had offered little in the way of food except palm-tops,” Roosevelt wrote. “We had lost four canoes and one man. We were in the country of wild Indians, who shot well with their bows. It behooved us to go warily, but also to make all speed possible, if we were to avoid serious trouble.”
  27. warily
    in a manner marked by keen caution and watchful prudence
    “So far the country had offered little in the way of food except palm-tops,” Roosevelt wrote. “We had lost four canoes and one man. We were in the country of wild Indians, who shot well with their bows. It behooved us to go warily, but also to make all speed possible, if we were to avoid serious trouble.”
  28. din
    a loud, harsh, or strident noise
    Above the din of the rapids, the men could hear the wooden canoes scraping and thumping into the rocks.
  29. churlish
    rude and boorish
    “I had urged, and Kermit had urged, as strongly as possible that the name be kept as Rio da Dúvida [River of Doubt]. We felt that the 'River of Doubt’ was an unusually good name...But my kind friends insisted otherwise, and it would be churlish of me to object...I was much touched by their action, and the ceremony itself,” Roosevelt wrote.
  30. buoyancy
    the tendency to float in water or other liquid
    The wood from the tatajuba tree proved to be too hard and heavy, and its lack of buoyancy contributed to the canoe’s demise.
  31. demise
    the time when something ends
    The wood from the tatajuba tree proved to be too hard and heavy, and its lack of buoyancy contributed to the canoe’s demise.
  32. deteriorate
    grow worse
    All they knew for certain was that the deteriorating conditions had brought out the worst in Julio.
  33. clad
    wearing or provided with clothing
    “There is a universal saying...when men are off in the wilds...they show themselves as they really are...A man may be a pleasant companion when you always meet him clad in dry clothes, and certain of substantial meals at regulated intervals, but the same cheery individual may seem a very different person when you are both on half rations, eaten cold, and have been drenched for three days—sleeping from utter exhaustion, cramped and wet,” Kermit wrote.
  34. perish
    pass from physical life
    “Kermit was extraordinarily lucky to escape alive from the accident in which Simplicio perished,” said Roosevelt.
  35. careen
    move at high speed and in an uncontrolled way
    Cherrie, himself suffering from painful tick bites, was standing at the foot of the rapids and watched as three camaradas held on to a rope tied to two canoes that were careening down a narrow channel.
  36. ensnare
    catch in or as if in a trap
    When the canoes came around a sharp bend, jagged rocks unexpectedly grabbed a hold of one while a tangle of vines and fallen trees ensnared it.
  37. precarious
    fraught with danger
    The young Roosevelt told Rondon that he had complete confidence in his own rope skills. Kermit believed that he would be able to transport some—if not all—of the empty canoes down the precarious rapids and waterfalls.
    It was a dangerous, if not impossible, proposition. Nevertheless, Cherrie and Lyra backed him up, believing Kermit’s plan was their best chance.
  38. proposition
    a suggestion offered for acceptance or rejection
    The young Roosevelt told Rondon that he had complete confidence in his own rope skills. Kermit believed that he would be able to transport some—if not all—of the empty canoes down the precarious rapids and waterfalls.

  39. relent
    give in, as to influence or pressure
    Rondon listened carefully and finally relented. But he knew it was going to be the toughest portage to date, and so he ordered everyone to leave behind what they didn’t absolutely need.
  40. scavenge
    feed on carrion or refuse
    Cherrie knew that this type of bird, a scavenging bird of prey, didn’t live in the forest, so it was possible that once they traveled through this chain of mountains, they would reach open country, which would make their journey easier.
