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.

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.
The Federal Government’s capabilities are organized into Emergency Support Functions (ESFs) to facilitate and coordinate the Federal response. These ESFs are designed to address the most frequent needs of States, Tribes, Territories, and local communities after a major event. There are currently fifteen (15) ESFs.
Emergency Support Function (ESF) #11 Agriculture and Natural Resources - is one of the fifteen ESFs that make up the National Response Framework (NRF). Federal response is coordinated through the ESFs after a Presidential Disaster Declaration is issued.
ESF #11 Agriculture and Natural Resources consists of five component areas:
Provide nutritional assistance to affected areas
Respond to animal and plant diseases
Ensure the safety and security of the commercial food supply
Provide for the safety and well-being of household pets
Protect natural and cultural resources, and historic properties (NCH)
The United States Department of Agriculture (USDA) is the primary Agency for the first four components of ESF #11 and serves as the coordinating agency for the entire ESF, USDA is charged with providing managerial oversight throughout the preparedness and response phases of the incident. The United States Department of the Interior (DOI) is the primary agency for the fifth component - protection of natural and cultural resources and historic properties. USDA and DOI work together to ensure a coordinated and effective response to all emergencies.
