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 requirements for SAM (System of Award Management) registration have changed. You are only required to register in SAM if you enter into a contractual agreement with the Federal Government. PILT payment recipients (vendors) are NOT REQUIRED to register in SAM even though electronic payment is the most cost-effective, convenient method of payment. We encourage you to register in SAM.
Existing Vendors (Local units of government that have previously received PILT payments)
If you are currently registered in SAM, you are required to update or renew your registration at least once a year in order to maintain an active status. The SAM website is https://www.sam.gov/portal/SAM/. Changes will interface into our financial system so that you can receive your 2017 PILT payment electronically.
If you are not registered in SAM and want to continue to receive an electronic payment and have updates to your banking information, please request a vendor update form.
If you wish to continue receiving a check and your address information has changed, please request a vendor update form. An EFT waiver form is required.
New Vendors (Local units of government that are receiving PILT payments for the first time)
