This earthquake has received inore intensive study from all scientific disciplines and specialties than any single previous natural disaster. In a series of six Professional Papers, the U.S. Geological Survey has published the results of a comprehensive geologic study that began, as a reconnaissance survey, within 24 hours after the event and extended, as detailed investigations, through several field seasons. Professional Paper 541 de- scribed early field investigations and reconstruction efforts; 542, in seven parts, the effects of the earthquake on Alaskan communities; 543, in 10 parts, the regional geologic effects; 544, in five parts, the worldwide effects on the earth's hydro- logic regimen; 545, in four parts, the effects on Alaska's transportation, communications, and utilities.

WILLIAMS, Jr., and JANE G. FERRIGNO U.S. GEOLOGICAL SURVEY PROFESSIONAL PAPER 1386–J–1 The Rocky Mountains of Canada include four distinct ranges from the U.S. border to northern British Columbia: Border, Continental, Hart, and Muskwa Ranges. They cover about 170,000 km2, are about 150 km wide, and have an estimated glacierized area of 38,613 km2. Mount Robson, at 3,954 m, is the highest peak. Glaciers range in size from ice fields, with major outlet glaciers, to glacierets. Small mountain-type glaciers in cirques, niches, and ice aprons are scattered throughout the ranges. Ice-cored moraines and rock glaciers are also common CONTENTS Page Abstract ---------------------------------------------------------------------------- J199 Introduction----------------------------------------------------------------------- 199 FIGURE 1.

    National Park Service North Cascades National Park Service Complex U.S. Department of the Interior Stephen Mather Wilderness An Enduring Legacy of Wilderness “[I]t is hereby declared to be the policy of the Congress to secure for the American people of present and future generations the benefits of an enduring resource of wilderness.” — Wilderness Act, 1964 The North Cascades National Park Complex includes 684,000 acres in three units: North Cascades National Park, Lake Chelan National Recre- ation Area, and Ross Lake National Recreation Area. Congress has designated 94% of the Complex as the Stephen Mather Wilderness. Today, as in the past, wilderness is an important part of every American’s story. People seek out wilderness for a variety of reasons: physical or mental challenge; solitude, renewal, or a respite from modern life; or as a place to find inspiration and to explore our heritage. What draws you to visit wilderness? The Stephen Mather Wilderness is at the heart of over two million acres of some of the wildest lands remaining, a place “where the earth and its community of life are untrammeled by man….” Untrammeled (meaning“free of restraint,” “unconfined”) captures the essence of wilderness: a place where the natural processes of the land prevail, and the developments of modern technological society are substantially unnoticeable. Here, we are visitors, but we also come home—to our natural heritage. It is a place to experience our past, and a place to find future respite. This is the enduring legacy of wilderness. To Hope, B.C.
