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.
Thank you for inviting the Department of the Interior to testify on S. 1272, the Devil's Staircase Wilderness Act of 2009.The Bureau of Land Management (BLM) supports S. 1272 as it applies to lands we manage, and we would like to work with the sponsor and the Committee on minor refinements tothe bills.
The proposed Devil's Staircase Wilderness, near the coast of southwestern Oregon, is not for the faint of heart.Mostly wild land and difficult to access, the Devil's Staircase reminds us of what much of this land looked like hundreds of years ago.A multi-storied forest of Douglas fir and western hemlock towers over underbrush of giant ferns, providing critical habitat for the threatened Northern Spotted Owl and Marbled Murrelet.The remote and rugged nature of this area provides a truly wild experience for any hiker.
S. 1272 proposes to designate nearly 30,000 acres as wilderness, as well as portions of both FranklinCreek and Wasson Creek as components of the Wild and Scenic Rivers System.The majority of these designations are on lands managed by the U.S. Forest Service.The Department of the Interior defers to the U.S. Department of Agriculture on those designations.
Approximately 6,100 acres of the proposed Devil's Staircase Wilderness and 4.2 miles of the Wasson Creek proposed designation are within lands managed by the BLM.The Department of the Interior supports these designations and would like to work with the sponsor and the Committee on minor boundary modifications to improve manageability.
We note that while the vast majority of the acres proposed for designation are Oregon & California (O&C) lands, identified under the 1937 O&C Lands Act for timber production, however, the BLM currently restricts timber production on these lands.These lands are administratively withdrawn from timber production by the BLM, either through designation as an Area of Critical Environmental Concern or through other classifications.Additionally, the BLM estimates that nearly 90 percent of the area proposed for designation is comprised of forest stands that are over 100 years old, and provides critical habitat for the threatened Marbled Murrelet and Northern Spotted Owl.
The 4.2 miles of Wasson Creek would be designated as a wild river to be managed by the BLM under S. 1272.The majority of the acres protected through this designation would be within the proposed Devil's Staircase wilderness designation, though 752 acres would be outside the proposed wilderness on adjacent BLM lands.
The designations identified on BLM-managed lands under S. 1272 would result in only minor modification of current management of the area and would preserve these wild lands for future generations.
Thank you for the opportunity to testify in support of theseimportant Oregon designations.The Department of the Interior looks forward to working with the sponsors and the Committee on minor modifications to the legislation and to welcoming these units into the BLM's National Landscape Conservation System.
