Phil Stagg wrote guidebooks for several of the waterfalls to be found in Michigan, the state I live in. This is number one in the series. It's obvious Stagg knows what he's talking about. In this edition, and I'm assuming it holds true for the other three so far published, the photography is his. He can tell you exactly how to get to the falls, which is the best location for photography, whether you should wear waterproof foot gear, the need for 4WD, and a host of other necessary things to know.
The fact that he includes so much information makes this a guidebook that leaves little to find out on your own except where to stay locally when you're investigating the various waterfalls. Stagg even includes a rating for each fall (from 1-10) based on his experience of "must see." While the Upper Tahquamenon Falls is the most well-known falls in Michigan, Stagg lists several other falls that have high "must see" ratings like it. Wagner Falls, Munising Falls and Miners Falls, to name a few. Visiting the various falls in Alger County includes the bonus of being close to Pictured Rocks National Lakeshore.
Stagg makes a couple of nice additions to explaining what you need to know to get to and see the falls. First, he offers a little history about each county you'll be visiting. Second, he carefully reminds us that some of the falls may be on private property and to speak with the owners of the land before going forward.
If exploring the hiking trails of Michigan to discover some beautiful falls and cascades found on the rivers of the Great Lake State sounds good to you, pick up this book. You'll have all the detailed information you need and the author's enthusiasm and expertise to help you get there.
