"The Civilian Conservation Corps, one of the very first -- and very successful -- efforts of Franklin D. Roosevelt's presidential administration, was created to put unemployed young men to work performing conservation and related activities during the depths of the great Depression while simultaneously striving to restore the bodies, minds, and spirits of the men themselves. During the nine years that the CC was in existence -- from 1933 to 1942 -- more than three million men planted billions of trees, erected hundreds of fire towers, constructed lakes and dams, blazed thousands of miles of trails, planned and graded roads, and built numerous cabins, lodges, shelters, bridges, and other structures. This work of the CCC placed a rich, distinct, and durable imprint on more than 700 local, state, and national parks throughout the United States -- and in the process created a personality of landscape that generations have sine come to recognize and appreciate as an inherent part of their -- and the nation's -- outdoor experience. 'Our Mark on This Land, ' identifies, describes, and provides access information to more than 300 parks spread throughout the United States that provide the best remaining examples of CCC workmanship. As such, it is a treasure trove of destinations at which the living legacy of the CCC may still be experienced -- and ever more at which the living legacy of the CCC may still be experienced -- and ever more at which the living legacy of the CCC may still be experienced -- and ever more fully appreciated for the recreational and historical importance of this program provided all who value and appreciate America's local, state, and national parks" -- p.4 of cover
