The establishment of Shenandoah National Park in 1935 was the culmination of an effort that took almost four decades. It was the result of the efforts of many people with many different motivations. Some saw the creation of the park as a significant effort in environmental preservation, others as an important step in providing a healthy outlet for the needs of a growing urban population, and some saw a national park as a means to bolster Virginia's economy through tourism. All of the these would be proven correct in time.
But the early boosters did not, at first, take into account the impact park establishment would have on the families that owned land and lived within the park boundary. Nor did they envision the traumatic events that would be initiated in late October, 1929. The Great Depression, its impact on two Presidents, and the creation of the Civilian Conservation Corps, are themes that are intimately woven into the fabric of the park story.
