The March 2014 Sunset has a section called “The Ultimate Guide to the West’s Classic National Parks” and devotes four pages to Yellowstone, including an entertaining essay by novelist Nevada Barr and write-ups on five other popular parks.
I learned that there are now 59 national parks, with 40 of them in western states. A sidebar quotes geyser guru T. Scott Bryan on why he (and I!) love geysers.
Just a couple of items of advice to visitors could be improved upon. To “ogle bears,” both black and grizzly, I would not suggest the Lamar Valley but more likely the Tower-Roosevelt area or even around Canyon or Mammoth. “About 100 gray wolves. . . can be spotted near the Blacktail Plateau” is misleading; best chances for viewing wolves have usually been some 20 or 25 miles east of there on the Northeast Entrance road; second best may be in Hayden Valley—but, then, you really never know where wolves or bears are going to be.
About boating on Yellowstone Lake, the suggestion to “rent a boat and paddle out onto the blue waters” is tempting, but they need just a few words of warning about the very common afternoon storms or perhaps even a mention that at least 40 people have drowned in the lake, many in small boats.
