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.

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.
Secretary Salazar Awards $27.74 Million Contract for Construction of the Navajo Nation Municipal Pipeline
Last edited 4/25/2016
WASHINGTON, D.C. – Secretary of the Interior Ken Salazar announced today that the Bureau of Reclamation has awarded a contract totaling $27.74 million to the Navajo Engineering and Construction Authority for the construction of Reaches 2 through 6 of the Navajo Nation Municipal Pipeline. NECA, a construction firm wholly-owned and operated by the Navajo Nation, will use the funds to construct the remaining 21-mile stretch (out of a total project of 29 miles) of the municipal pipeline..
"It gives me great pleasure to announce the award of this contract for constructing additional phases of the Navajo Nation Municipal Pipeline as it signifies ongoing progress towards completion of the Animas-La Plata Project,” said Secretary Salazar. “When completed, the pipeline will carry much-needed water to the communities served by the Navajo Tribal Utilities Authority in the vicinity of Shiprock, New Mexico.”
Constructing Reaches 2 through 6 of the pipelinewill entail the excavation and burial of 21 miles of PVC pipeline (24-inch diameter) and the construction of a 1-million gallon water storage tank near Nenahnezad Hill.
The Navajo Nation Municipal Pipeline was authorized as part of the Animas-La Plata Project by the Colorado Ute Settlement Act Amendments of 2000 to provide for the delivery of 4,680 acre-feet of municipal and industrial water per year from Farmington to Shiprock. The pipeline will follow the approximate alignment of the existing Farmington-to-Shiprock pipeline and will connect to existing distribution service laterals that serve communities in the Upper Fruitland, San Juan, Nenahnezad, Hogback, Shiprock, Cudei and Beclaibito Chapters.
“Construction of the Navajo Nation Municipal Pipeline is the by-product of dedicated workers, planning and design teams, project sponsors and beneficiaries joining together and contributing their training, talents and passion to complete this job,” said Reclamation Commissioner Michael L. Connor.
The Animas-La Plata Project fulfills the requirements of the 1988 Colorado Ute Indian Water Rights Settlement Act and the Colorado Ute Settlement Act Amendment of 2000. When completed, the project will provide the Navajo Nation, Southern Ute Indian Tribe and Ute Mountain Ute Tribe and the people of the Four Corners area with a reliable water supply for their future needs, without taking scarce water resources away from existing water users in southwestern Colorado and northwestern New Mexico.
The Navajo Engineering and Construction Authority, based in Shiprock, is a minority commercial construction company owned and operated by the Navajo Nation. The company has extensive experience in all phases of construction and related engineering disciplines, including: heavy civil construction, road building, water distribution systems and municipal improvements.
