Mercury's surface in "enhanced color," a color scheme created to emphasize color differences. This is not what Mercury would look like to the human eye, but by applying mathematical analysis to images, color differences can be accentuated beyond those visible to a person.
Mount Rushmore National Memorial under construction.
The workers had to endure conditions that varied from blazing hot to bitterly cold and windy. Each day they climbed 700 stairs to the top of the mountain to punch-in on the time clock. Then 3/8 inch thick steel cables lowered them over the front of the 500-foot face of the mountain in a "bosun chair." Despite the dangers, no one was killed during the project.
Otters in Glacier Bay National Park and Preserve, Alaska.
The sea otter population of Glacier Bay has increased dramatically in the past 20 years. Ecologists consider sea otters a keystone species here. Otters consume vast quantities of clams, urchins, crabs, and other invertebrates and their presence creates ripples through the ecosystem. NPS photo.
Every day someone like you becomes a wildland wildfire fighter, a teacher, a trail-builder, a museum curator, or a park ranger. Discover your opportunities in national parks. Come to play. Come to learn. Come to serve. Develop your environmental leadership skills. Find a job. Be the next generation to preserve and protect these great places.
With more than 80% of Americans living in urban areas, urban parks are more important than ever. The father of American landscape architecture, Frederick Law Olmsted, said of urban parks:
It is one great purpose of the Park to supply to the hundreds of thousands of tired workers, who have no opportunity to spend their summers in the country, a specimen of God's handiwork that shall be to them, inexpensively, what a month or two in the White Mountains or the Adirondacks is, at great cost, to those in easier circumstances.
TODAY: Secretary Jewell, USGS to Release Oil and Gas Assessment for Bakken and Three Forks Formations
Last edited 4/27/2016
WASHINGTON – Secretary of the Interior Sally Jewell and other Interior leaders will participate in a press teleconference this morning to release the U.S. Geological Survey's (USGS) updated oil and gas resource assessment for the Bakken Formation and a new assessment for the Three Forks Formation – both located in the Williston Basin in Montana, North Dakota and South Dakota.
Joining Secretary Jewell will be Assistant Secretary for Water and Science Anne Castle, USGS Acting Director Suzette Kimball and Brenda Pierce, USGS Energy Resources Program Coordinator.
Since a 2008 USGS assessment of the Bakken Formation, more than 4,000 wells have been drilled in the Williston Basin, providing important new subsurface geologic data. Previously little data existed on the Three Forks Formation and it was generally thought to be unproductive. The USGS undertook the assessment as part of a nationwide project assessing U.S. petroleum basins using standardized methodology and protocol.
The teleconference is open to credentialed media representatives by calling 1-888-947-9021 and entering access code: INTERIOR.
