Visit Arches and discover a landscape of contrasting colors, landforms and textures unlike any other in the world. The park has over 2,000 natural stone arches, in addition to hundreds of soaring pinnacles, massive fins and giant balanced rocks. This red rock wonderland will amaze you with its formations, refresh you with its trails, and inspire you with its sunsets.
A rugged, whitewater river flowing northward through deep canyons, the New River is among the oldest rivers on the continent. New River Gorge National River in West Virginia encompasses over 70,000 acres of land along the New River, is rich in cultural and natural history, and offers an abundance of scenic and recreational opportunities.
Denali is six million acres of wild land, bisected by one ribbon of road. Travelers along it see the relatively low-elevation taiga forest give way to high alpine tundra and snowy mountains, culminating in North America's tallest peak, 20,310' Denali. Wild animals large and small roam un-fenced lands, living as they have for ages. Solitude, tranquility and wilderness await.
Speech: OIA-DOI Museum Brown Bag -- Monitoring the Earth with 40 Years of Landsat Data
Dr. Bruce Quirk, Program Coordinator of the Land Remote Sensing Program at the US Geological Survey
Rachel Carson Room, Stewart Lee Udall Department of Interior Building
For four decades, Landsat satellites have continuously acquired space-based images of the Earth's land surface, coastal shallows, and coral reefs. The Landsat Program, a joint effort of the U.S. Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA), was established to routinely gather land imagery from space. Dr. Bruce Quirk discussed the Landsat program and the continuous global record it has revealed.
This lecture was held in conjunction with the celebration of the 40th Anniversary of the launch of the first Landsat satellite on July 23, 1972. As the world's longest-running Earth-observing satellite program, Landsat provides a comprehensive, impartial, and easy to access catalog of human and natural changes to the land. Landsat research is important in improving human health, environmental protection, biodiversity, energy production, water management, urban planning, disaster recovery, and crop monitoring.
