Ann Zwinger

Downcanyon is a wonderfully illustrated down-the-river adventure, but I would suggest using it as more of a reference book or guide than a white-rapids read. The map is fascinating and it was certainly fun to read the travels along it. But, my favorite parts were the rest areas, the stopping for the night. Zwinger took that opportunity to focus on the flowers, the reptiles, and the animals and the rock formations. It is here that Zwinger zeros in on the very nature of things (the foraging and nesting of bumblebees, for example).
Another pleasing point to Downcanyon was the addition of quotes from other explorers before each chapter. It's as if Zwinger is giving a nod to those who went down the Colorado with far less in every sense. Less equipment, less experience, less education. Those who went before were more daring, more adventurous, and without a doubt, put themselves in far more danger. Downcanyon is the exploration of the Colorado River for Zwinger and Zwinger alone.… (mere)
