Colbert, E.; Johnson, R.

Symposium discussing many of the facets of the Petrified Forest National Park, including it's local geology, geologic histories, art, air quality, and an examination on the plague's presence in PFNP. The Director of the National Park Service, Russell Dickenson, recently stated, 'The people of the United States have built the largest and most abundant system of National Parks in the world, an achievement benefiting the scope and grandeur of the nation's resources.' Petrified Forest National Park was first established as a National Monument by President Theodore Roosevelt on December 8,1906. The National Monument was established to preserve the mineralized remains of Mesozoic Forests commonly known as the 'Petrified Forest,' the natural environment, and cultural resources for public use and benefit. Full national park stuatus for Petrified Forest National Monument was a long cherished dream of many Arizonans and others throughout the United States. This cherished dream came true on December 8, 1962, when Petrified Forest did gain status as out country's thirty-first national park. The park celebrated its seventy-fifth anniversary in 1981 with activities planned throughout the entire year to commemorate its establishment. The research symposium of November 6-7, 1981, was part of this commemoration. I am extremely pleased that such an outstanding representation of researchers presented their findings at the symposium and also completed written reports to be included in this volume of papers. My personal thanks to all researchers for taking time from their busy schedules to participate. The symposium's success, which is reflected in this publication, provides information that will enhance the public's interest and enjoyment of Petrified Forest National Park both now and in future generation.
