The Big One Opportunities That Rainier Has to Offer, Just in Time for You to Start Making Your Own Summer Hiking Plans
May + June 2011 » Washington Trails 21 On Trail Northwest Explorer » Living in the Northwest, we have no shortage of wilderness locations to escape into for a day—or a week. On any ol’ weekend, we could be climbing to the rim of smoldering Mount St. Helens, journeying through lush rain forests in the Olympics or trekking across the jagged ridges of the North Cascades. And while all of these places, and so many more locations, are outstanding, nothing quite compares with the majesty—or sheer immensity—of “The Mountain.” But when you think about hiking that Mountain, where do you even start? With over 240 miles of hiking trails (not counting mountaineering routes), spread over 378 square miles, there’s a lot to choose from. Add to that the incredible amount of scenic features—473 streams and rivers, 292 lakes, 122 waterfalls, 25 named glaciers, and more meadows, valleys, wildflowers, old-growth forest, and mind- numbing views than you can shake a trekking pole at—and the task of choosing a trail can no doubt be daunting. Thankfully, there are stacks of helpful guidebooks available to get you started. But even as great as most of those guidebooks are—full of inspiring photos and informative elevation profile graphs (a feature I particularly appreciate)—you’re still trying to whittle down from 50-plus options. And if you’re unfamiliar with The Mountain, what you’re really thinking Backpacking is, “Where do I go to get the really good stuff?” Well, this month, you’re in luck. From shorter starter trails to the granddaddy of round-the- mountain adventures, we’ll highlight five—and only five—of the most outstanding hiking the Big One opportunities that Rainier has to offer, just in time for you to start making your own summer hiking plans. -

Mount Rainier National Park Place Names
Mount Rainier National Park Place Names Gary Fuller Reese. April 10, 2009. PREFACE. Because of its prominence as the "Great Mountain of the Pacific Northwest" Rainier was one of the first features in the Pacific Northwest named by early explorers. The center of a National Park since 1899 most prominent features around the mountain have received names, some of which have become official and some of which a common use. In 1919 Mount Rainier National Park Superintendent Roger Toll wrote about names in the National Park: "The park service is interested in having names applied to the various...scenic points that are now unnamed....the most desirable names...are the original Indian names, or, if these are too long and unpronounceable their English equivalents are often very good. "If no original name can be found, and a name is to be supplied, the Indian names may be drawn upon with advantage, but this should be done by an expert...Descriptive names are good. The only thing most difficult to avoid is the indiscriminate naming of scenic features after persons." While name origins have been found for many locations within the National Park there are a number of places for which origins are missing, especially on the northern side of the mountain. In 1916 Edmond S. Meany wrote about Mount Rainier. He listed many places for which he could not find a name origin. In 1932 the writers of the Encyclopedia of Information on Mount Rainier National Park made a list of locations on the mountain recording that they were unable to supply origins for numbers of them. -
