A perusal of these pages suggests that the enthusiastic cooperation of regional mountaineering and outdoor clubs and related agencies, in response to the “Appeal to Reason” circulated by the American Alpine Club three years ago, has begun to take effect, it is an indication of progress that, with the exception of the two tragedies in Yosemite in 1949, and the minor accident on Mt. Pilchuk in the Northern Cascades, no report of a serious mountain accident has been received from the Sierras, the Washington Cascades or the Tetons. These three ranges produced the largest number of mountain accidents during the 1947 and 1948 climbing seasons. The most truly serious mountain accidents throughout the United States during the past climbing season were restricted mainly to young persons of the general public who were inexperienced and who were not members of an organized group. The need for directing these young enthusiasts into well-organized clubs is obvious. It is still clear, however, that not only novices and inexperienced persons get into trouble, but also some experienced climbers who fail to use good judgment or who leave too much to fate. For these reasons, continued vigilance is in order; and a reminder now and then should be taken in good grace, as insurance on the pleasure and inspiration the mountains give.
