This was an enjoyable and detailed account of Bob Marshall's exploration of the Brooks Range near Gates of the Arctic National Park. Parts of the account were dry, but they were punctuated with eexciting encounters with grizzlies, flooded camps, and the like. This book stood out from other exploration books for a couple reasons:
1) For a white man in the 1930s, he was very careful to chalk up his 'firsts' only as a first to white men, acknowledging that native Alaskans may well have explored some of these areas before.
2) He really conveys the difficulty of getting the complex geography correct. He did this not by whining, but by freely and humorously sharing his incorrect deductions of which river must have drained down which range. He was also quick to share the credit with his traveling companions for his accomplishments.
By the way, this dude was a beast! Offhandedly mentioning 30 mile trailless days, some harrowing scrambles, etc. His love of wilderness areas, the native Alaskans, and the pioneers of the area really shine through in this book. It's a fitting legacy that such a wide swath of American wilderness bears his name today.
