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.
The revised guidance reflects recent research findings and shifts in the ecology of influenza viruses. It also provides additional information related to handling birds including the need for influenza vaccinations and anti-viral medication for DOI personnel, and the need for personal protective equipment (PPE).
In addition to providing updated guidance, this serves as a reminder to DOI personnel, as well as their supervisors and managers, to be mindful of the tendency to minimize risk. This creates an environment where behaviors are accepted because they have not resulted in adverse effects to the individual in the past. Managers, supervisors and employees need to be watchful of this tendency and must implement robust management and supervisory controls to prevent this from occurring in all types of field operations. Personnel also need to be mindful of one another and correct their peers when they are engaging, or preparing to engage, in behaviors that may get them or others hurt or ill.
The guidance was updated through a joint effort of the DOI One Health Group and OSH. The DOI One Health Group is led by CDR Elaine Bond, U.S. Public Health Service Officer detailed to OEM, and consists of representatives from BIA, BLM, BOR, FWS, NPS, USGS, OEM and OEPC that encompass the group's core areas of public health, wildlife health and environmental health. The group's mission is to utilize a Department-wide interdisciplinary coordinated approach, commonly referred to as “One Health”, to promote the health of all species and the environment in the stewardship of our public lands through sound science and inter-agency collaboration to inform policy and management decisions.
