0n May 24, 1869, a one-armed Civil War veteran named John Wesley Powell and a ragtag band of nine mountain men embarked on the last great quest in the American West. No one had ever explored the fabled Grand Canyon; to adventurers of that era it was a region almost as mysterious as Atlantis -- and as perilous.

The ten men set out down the mighty Colorado River in wooden row

I loved the author's newest book, The Rush: America's Fevered Quest for Fortune, 1848-1853 so I looked for other's he has written. I enjoy history written from journals and thought the topic of being the first to run the rapids through the Grand Canyon would be an excellent topic. Not to be.

The story was all over the place diverting to various places that went beyond supplying the pertinent information for the story to excess detail that need not be part of the book. I did not want a history of
I read the book in preparation for an upcoming trip to the Grand Canyon. I read it in my methodical style as I do such books constantly referring to maps and googling other references to increase my understanding. It has me super-excited about the trip!

It is a great book about an epic 1000 mile journey down the Green and Colorado Rivers through the Grand Canyon in 1869, led by a man-John Wesley Powell, who had one arm amputated during the Civil War. It is a gripping story with lessons on geology
This is the weakest adventure/exploration-type book I've read so far and I don't recommend it. Most of it is pretty damn boring. It gets a little more interesting towards the end, but only for a little bit. The interesting bit concerns the situation at the end of their trip down the Colorado river through the Grand Canyon. No one had ever been all the way down it before, on boat or foot, so they had no idea what was in store for them. For most of the trip they had dealt with this by exploring th ...more
That the author was so present in the telling of this story was both its best and worst feature. He brings context to events and circumstances, but he does so through odd illustrations. For instance, he describes a boatman stuck in a muddy whirlpool as being in the center of a massive glass of chocolate milk as it is stirred by a giant 8-year old. It was consistently distracting, but I think it enhanced my understanding of the challenges the expedition team faced in the process of exploring the ...more

This book is part Civil War history (battle of Shiloh, where Powell became an amputee of one arm: yes a one-arm man led the expedition!), part explanation of the geology and theology 19th Century controversies and mindsets, part documentary, epic journey narrative, and scholarly history, based on original contemporaneous documents written by percipient witnesses, and other concurrent sources which are noted, for further reading. He declares it is non-fiction, and he has stayed true to original a ...more
Living in northern Arizona, about one hundred miles from the Grand Canyon, ready to celebrate Prescott's sesquicentennial, and having read and enjoyed another of Edward Dolnick's books ("The Clockwork Universe," about Sir Isaac Newton), I decided to read this book. It is a very well documented story of John Wesley Powell's expedition down the Green and Colorado Rivers and the hardships they endured with that adventure. I also enjoyed the many side stories that Mr. Dolnick included in the book. D ...more
Wesley Powell reminded me of Ernie Shackleton and his voyage - strewn with unbelievable people, an almost fool-hardy mission, terrible odds and certain death on a daily basis, yet, all escaped unscathed. Okay, all people who stayed with the expedition escaped.

Edward Dolnick’s narrative is very descriptive with enough background on the times, events and people involved. He has researched his material thoroughly and kudos for that. At times, I did feel that the description was a bit more extensiv
This is one of the real classic adventure stories of our nation. In many ways superior to Lewis and Clark because of the daily challenges of rapids, unknown canyons, lack of food, and lack of experience. This truly was a journey on a blank spot on the map and the way this band of men made their journey safely through the continents most challenging rapids would seem to be fiction - but it is true.

Story of the 1,000 mile voyage down the Green and Colorado rivers in the summer of 1869. The ten men who undertook it were led by one-armed John Wesley Powell and were reduced to six by the end. They were the first to traverse the Grand Canyon. Inexperienced and badly outfitted they encountered over 400 separate rapids. They finished the journey as their remaining food- flour and dried apples- was running out. Three men who decided to leave the expedition less than 24 hours from its end walked o ...more
'Down the Great Unknown' about John Wesley Powell's 1869 expedition to map the rivers to and through the Grand Canyon is a very good (and relatively quick at 292 pp.) read. The book focuses on the expedition itself and leaves out extraneous information. The author (Dolnick) does a very good job of taking the 3 different diaries to form a narrative of the trip taken (initially) by 10 adventurers. What amazes is the not oftened mentioned fact that Powell had only one good arm. Suffice to say, ther ...more
This is a non-fiction account of the first Powell expedition down the Green River on through the Colorado River and Grand Canyon. The account is based on journals from three of the ten men who started the hard and desperate journey. Having lived in Green River, WY and having hiked in that region as well as the Grand Canyon, I was keenly interested in the descriptions and series of events. The multiple perspectives presented made it a good first choice to read about the expedition. I enjoyed it a ...more
In 1869 John Wesley Powell decided to set off down the Green River and follow it to the Colorado and then down the Colorado through the Grand Canyon. All of this was territory that had been unexplored by Europeans. Edward Dolnick recounts the passage in Down the Great Unknown. It's a fascinating story told masterfully of a courageous -- or foolish -- adventure.

His companions had no experience running rapids and their equipment was sturdy but not designed for shooting rapids. Fortunately, by star
Kathleen Hulser
Gripping tale fleshed out with highly useful commentary on shooting rapids, river craft, boater drownings and other material designed to make you realize how very extraordinary or foolhardy the expedition led by the one-armed Powell was. In 1869 they did not even face down river, as they rowed their absurdly heavy Whitehall boats towards the rapids. Powell would hold onto a strap to keep from being thrown, as he called out rock hazards. They lined and portaged the heavily loaded boats, as their ...more

I just couldn't put this book down once I started it--shall I blame it on the rapids or the writer?

Most accounts of the Colorado River Exploring Expedition focus on Powell and his account of the trip, but Dolnick elevates two other accounts by crew members to tell the story of the trip. The focus is on the rapids and the barreling river, rather than on Powell. Even better, Dolnick regularly breaks into the narrative to offer modern takes on many of the rapids by experienced boatmen.

The science o
If you enjoy true stories of courage and exploration, this book is for you. Major Powell and 9 others journeyed through the Grand Canyon in wooden boats, the first white men known to do so.
One man left the group at the first opportunity after one of their boats was destroyed early on. The rest faced extreme temperatures, rain, rapids, lost supplies, food that went rancid or moldy, and more rapids. Lining the boats or portaging them, was often necessary, but difficult work and time consuming.

Really!? That happened? Wow. Reading about Powell's trip reminds me of when I first read about Shackleton's Antarctic adventures. Wow. I enjoyed this book all the more because my family and I visited the Grand Canyon for the first time last month. And because I'm a kayaker; river stories are up my alley (down my canyon?).

I had considered reading Powell's book about this trip, but I'm glad I read this secondary source instead. Dolnick does a great job comparing what Powell wrote vs. what others

Spoiler Alert: There are whitewater rapids in the next chapter!

The story of John Wesley Powell's journey through the Grand Canyon is undoubtedly epic and an amazing testimony to the indomitable determination (and luck) of the rag-tag group of men who were first to brave the cliffs and rapids of the mighty Colorado River and the first to survey the full length of the Grand Canyon. Author Edward Dolnick provides an accessible narrative that captures not only the spirit of the adventure, but someth
One of the great true adventure stories of the past few centuries is surely John Wesley Powell's expedition down the unexplored Colorado River and through the Grand Canyon in 1869, a journey of some 1,000 miles in ninety-nine days. Ten poorly-prepared men set out in six ill-equipped wooden boats, but only six survived.

Powell, a multi-faceted one-armed Civil War veteran, was the leader of the group, and much like another of my favorite adventurer-heroes, Ernest Shackleton, probably singlehandedl
The Clockwork Universe was hard to put down, and I am not usually real intrigued with reading a book on science! I do hike and camp and always wanted to raft a river, and enjoy a good tale of an exploration/journey/courage in the face of danger. This journey through the Grand Canyon has all the necessary elements, but somehow it fell short for me. The hardships were great, and the men were brave. The story was well told, but on occasion I was skimming through, wanting to get to the end. I am gla ...more
This was an extremely gripping story about the first white men who (as far as history is concerned) got through the Grand Canyon in what amounted to row boats. They were incredibly lucky in the face of the unknown, and the book pulls you in from the beginning when they dump a bunch of supplies that are just too heavy (and end up starving later). How anyone as unprepared and inexperienced as this group of men made it a week let alone several months is mind-blowing.
C Miller
Absolutely riveting. Like many others, read this while doing a tour of the National Parks in Utah and Colorado. Fascinating as a narrative of the expedition and as a portrait of Powell. Well worth reading. Also check out Frederick Dellenbaugh - A Canyon Voyage: The Narrative of the Second Powell Expedition. Not quite as thrilling, but also well worth reading. The second expedition was fraught with its own unique problems.
Interesting though often dry

A solid overview of not only Powell's expedition, but other pertinent stories. From accounts of the American Civil War to frontier anecdotes to modern river running tales, Dolnick does an excellent job filling out the figures of the expedition and the canyon itself. Sadly, the tangents are often far more interesting than the expedition itself. That being said, it's still a worthwhile read.

I'm not a river / rafting type and I'm not a non-fiction reader by nature, but I have to admit - I really liked this book. The author can be a bit long-winded at times to make his point clear, but often it is worth it in the end. The story is amazing. You'll be blown away at the sheer courage of the expedition members and the trials they suffered through. They were the FIRST to go down the Grand Canyon and no one thought it possible. They had the wrong boats, no experience, and no knowledge of w ...more
Okay, I am a history fanatic! I will read those books found in sightseeing stores everywhere. So it is no wonder I got this book after visiting the Grand Canyon. But irregardless of my odd reading habits, this book was just so well written I had to give it 5 stars. Who would not like a true adventure story with rapids, feuds, and death defying luck all thrown in together! What an exciting read!
Before we started sending our kids down the Grand Canyon on donkeys, the Arizona territory was a frightful unknown. In 1869, one-armed Civil War veteran John Wesley Powell decided to brave the narrow strip of Colorado River with 9 men in wooden rowboats. Recreating the true story by examining journals and diaries, Dolnick takes us on the adventure of an audacious man on one doomed mission.
I read this excellent book in conjunction with my trip to the Grand Canyon. Seeing the places described really helped bring the text to life. Dolnick is an excellent writer who knows how to conduct exhaustive research and put it together into an engaging narrative. This book wasn't dry. Instead, it used the words of John Wesley Powell and two of his expedition crew who kept journals to describe the awesome trip they took in order to map and explore the Colorado River. They were the first organiz ...more
This story was great insight into the Civil War and the time after the war. For a non-fiction book, it is an exciting read. The fast pace and dangers of the rapids that Powell's crew ran are portrayed so well that the reader can envision being there. I would recommend this book to any history buff or anyone interested in a real-life survival story.

Really an excellent account of John Wesley Powell's expedition down the Green and Colorado Rivers from Wyoming through the Grand Canyon in 1869. The author does a great job explaining what they were facing and provides many good anecdotes to help the reader appreciate the obstacles. Having just been in the Grand Canyon helped me to visualize it as well. The book is based mostly on firsthand, contemperaneous accounts and he goes a good job of explaining the different personalities and tensions of
John Westley Powell was an idealistic, one-armed Civil War vet with the outlandish idea of rafting through the previously unexplored Grand Canyon. He and 9 others set out to do this in 1869. They really had no idea what they were getting into. They didn't bring life preservers (except for the disabled Powell) and brought wooden row-boats completely unsuited for the rapids ahead.

That seems like some pretty good elements for a great adventure story. And while the journey for Powell and his men was
Pretty informative book. Had heard about Powell's expedition while rafting the Grand Canyon myself. There was a lot of "at this point, the men were REALLY exhausted and low on food and super frustrated with Powell..." And then conditions would get even worse.

“The men had two favorite modes of speech, wild exaggeration and ludicrous understatement. Ideally, both were delivered deadpan. Time and again, the accounts overflow with an offhand vitality that reminds us that we are listening to Mark Twain's contemporaries.” 2 likes
