  • Under the setting moon, rising sun and a bald eagle flying above, Steve Lewis, Raptor Management Coordinator, U.S. Fish & Wildlife Service (left) and Rachel Wheat, a graduate student at the University of California Santa Cruz wait for bald eagles to land on the traps they set on the gravel bar of the Chilkat River. Each morning under the cover of darkness they would set their traps. The traps are being used to capture bald eagles that will be used in a study being conducted by Wheat. Once the traps are set, it is a matter of waiting -- and waiting. On some days no eagles were caught, on others, only one or two were caught. Wheat is conducting a bald eagle migration study of eagles that visit the Chilkat River for her doctoral dissertation. She hopes to learn how closely eagles track salmon availability across time and space. The bald eagles are being tracked using solar-powered GPS satellite transmitters (also known as a PTT - platform transmitter terminal) that attach to the backs of the eagles using a lightweight harness. During late fall, bald eagles congregate along the Chilkat River to feed on salmon. This gathering of bald eagles in the Alaska Chilkat Bald Eagle Preserve is believed to be one of the largest gatherings of bald eagles in the world.

  • The Mesquite Flat Sand Dunes located in Death Valley National Park near Stovepipe Wells, is the largest dune field in the park. While the sand dunes appear tall, the highest dune only rises about 100 feet. The Mesquite Flat Sand Dunes are the easiest sand dunes to visit in Death Valley National Park. Three types of dunes are found in the dune field: crescent, linear, and star shaped. The dune field is named for the Mesquite trees that create hummocks that provide places for wildlife to live. Here a lone hiker stretches as the dunes are bathed in the first light at sunrise.<br />

  • Male Columbian sharp-tailed grouse perform their mating dance on a lek during the pre-dawn in southern Wyoming.<br />
<br />
The Columbian sharp-tailed grouse (Tympanuchus phasianellus columbianus) is one of the seven recognized subspecies of North American sharp-tailed grouse. It is also the rarest and smallest of the subspecies of sharp-tailed grouse. Columbian sharp-tailed grouse have experienced declines in distribution and population due to overuse and development of the mountain shrub and grasslands that it favors. It is native to the sagebrush steppe of the western United States and British Columbia. First described by the Lewis & Clark expedition, Columbian sharp-tailed grouse were once the most abundant grouse in the West. Today, Columbian sharp-tailed grouse no occupy less than 10 percent of its historic range. It is currently considered a Species of Concern in several U.S. states.<br />
<br />
Like other grouse, Columbian sharp-tailed grouse congregate year after year in the spring on a small area known as a lek. Males perform highly animated dancing courtship displays to impress females to mate. These displays consist of rapidly stamping their feet at blur-like speed while keeping with their wings extended, often rotating in a circle.

  • A bald eagle (Haliaeetus leucocephalus) flies with a salmon carcass past ice covered trees sparkling in the golden light of sunrise at the confluence of the Tsirku and Chilkat Rivers in the Alaska Chilkat Bald Eagle Preserve. During November and December several thousand bald eagles come to the alluvial delta area at the confluence of the Tsirku and Chilkat Rivers near Haines, Alaska because of the availability of spawned-out salmon and open waters. The open water is due to a deep accumulation of gravel and sand that acts as a large water reservoir whose water temperature remains 10 to 20 degrees warmer than the surrounding water temperature. This warmer water seeps into the Chilkat River, keeping a five mile stretch of the river from freezing as quickly as other rivers in the area. The 48,000 acre area was designated as the Alaska Chilkat Bald Eagle Preserve in 1982.

  • A burrowing owl (Athene cunicularia), stand snext to the opening to an underground borrow located on the Hoeme Family Farm and Ranch near Healy, Kansas.<br />
<br />
Burrowing owls live in underground burrows, often that they have taken over from prairie dogs, tortoises, and ground squirrels. While most owls are active at night, borrowing owls are active during the day doing most of their hunting in the early morning or early evening. When threatened by a predator burrowing owl will retreat to the borrow and produce hissing and rattling sounds similar to that of a rattlesnake. Burrowing owls are often seen with just their eyes poking above the burrow hole.<br />
<br />
Control programs to limit or eradicate prairie dogs and ground squirrels have led to a sharp decline of burrowing owls who depend on the burrows dug by prairie doge and ground squirrels.

  • A 4,000-foot-high mountainside released approximately 120 million metric tons of rock in 60 seconds during a landslide onto the Lamplugh Glacier in Glacier Bay National Park and Preserve. In an interview with the Anchorage Dispatch News, geophysicist Colin Stark of Columbia University's Lamont-Doherty Earth Observatory, described the slide as “exceptionally large.” He compared the massive landslide to roughly 60 million medium SUVs tumbling down a mountainside.<br />
<br />
The slide occurred on the morning of June 28  in a remote area of Glacier Bay National Park in southeast Alaska. It was first observed by Paul Swanstrom, pilot and owner of Haines-based Mountain Flying Service. Swanstrom noticed a huge cloud of dust over the Lamplugh Glacier during a flightseeing tour of Glacier Bay National Park several hours after the slide occurred. Swanstrom estimates the debris field to be 6.5 miles long, and one to two miles in width.<br />
<br />
Even two days later, as this aerial photo of the Lamplugh Glacier landslide shows, a dust cloud remained over the unstable mountainside due to still tumbling rock.

  • A spectacular display of the Aurora Borealis or as it is commonly called, the northern lights, occurred the evening of November 8 through the early morning of November 9, 2013 over Sinclair Mountain and other mountains in the Kakuhan Range at Haines, Alaska. The luminous glow in the upper atmosphere stretched across the skies above the Lynn Canal from Skagway to Juneau. The bottom edge of an aurora is typically 60 miles high with the top edge at an altitude of 120 to 200 miles, though sometimes high altitude aurora can be as high as 350 miles. The collision of sun storm electrons and protons with different types of gas particles in Earth’s atmosphere cause the different colors. Green, the most common color, is caused by the collision of electrons with atoms of with atomic oxygen. *** EDITORS NOTE: Boulders in foreground were lit with a flashlight during time exposure***

  • Denali (Athabaskan for "The High One") basks in morning light at sunrise in Denali National Park and Preserve in Alaska. The snow and glacier covered mountain, part of the Alaska Range soars to a height of 20,310 feet. Denali is the tallest mountain on the North American continent. Although Mt. Everest is higher, the vertical rise of Denali is greater. This view is a small detail from the north slopes of the mountain seen from Wonder Lake.

  • A 4,000-foot-high mountainside released approximately 120 million metric tons of rock in 60 seconds during a landslide onto the Lamplugh Glacier in Glacier Bay National Park and Preserve. In an interview with the Anchorage Dispatch News, geophysicist Colin Stark of Columbia University's Lamont-Doherty Earth Observatory, described the slide as “exceptionally large.” He compared the massive landslide to roughly 60 million medium SUVs tumbling down a mountainside.<br />
<br />
The slide occurred on the morning of June 28  in a remote area of Glacier Bay National Park in southeast Alaska. It was first observed by Paul Swanstrom, pilot and owner of Haines-based Mountain Flying Service. Swanstrom noticed a huge cloud of dust over the Lamplugh Glacier during a flightseeing tour of Glacier Bay National Park several hours after the slide occurred. Swanstrom estimates the debris field to be 6.5 miles long, and one to two miles in width.<br />

  • A spectacular display of the Aurora Borealis or as it is commonly called, the northern lights, occurred the evening of November 8 through the early morning of November 9, 2013 over Haines, Alaska. The luminous glow in the upper atmosphere stretched across the skies above the Lynn Canal from Skagway to Juneau. The bottom edge of an aurora is typically 60 miles high with the top edge at an altitude of 120 to 200 miles, though sometimes high altitude aurora can be as high as 350 miles. The collision of sun storm electrons and protons with different types of gas particles in Earth’s atmosphere cause the different colors. Green, the most common color, is caused by the collision of electrons with atoms of with atomic oxygen.

  • Steve Lewis, Raptor Management Coordinator, U.S. Fish & Wildlife Service (left), and Rachel Wheat, a graduate student at the University of California Santa Cruz, remove one of the leg snare traps they used catch bald eagles. Each morning under darkness they would set their traps. Then in the late afternoon they would remove them. Wheat is conducting a bald eagle migration study of eagles that visit the Chilkat River for her doctoral dissertation. She hopes to learn how closely eagles track salmon availability across time and space. The bald eagles are being tracked using solar-powered GPS satellite transmitters (also known as a PTT - platform transmitter terminal) that attach to the backs of the eagles using a lightweight harness. During late fall, bald eagles congregate along the Chilkat River to feed on salmon. This gathering of bald eagles in the Alaska Chilkat Bald Eagle Preserve is believed to be one of the largest gatherings of bald eagles in the world.

  • A burrowing owl (Athene cunicularia), stands in the opening to an underground borrow located on the Hoeme Family Farm and Ranch near Healy, Kansas.<br />
<br />
Burrowing owls live in underground burrows, often that they have taken over from prairie dogs, tortoises, and ground squirrels. While most owls are active at night, borrowing owls are active during the day doing most of their hunting in the early morning or early evening. When threatened by a predator burrowing owl will retreat to the borrow and produce hissing and rattling sounds similar to that of a rattlesnake. Burrowing owls are often seen with just their eyes poking above the burrow hole.<br />
<br />
Control programs to limit or eradicate prairie dogs and ground squirrels have led to a sharp decline of burrowing owls who depend on the burrows dug by prairie doge and ground squirrels.

  • A 4,000-foot-high mountainside released approximately 120 million metric tons of rock in 60 seconds during a landslide onto the Lamplugh Glacier in Glacier Bay National Park and Preserve. In an interview with the Alaska Dispatch News, geophysicist Colin Stark of Columbia University's Lamont-Doherty Earth Observatory, described the slide as “exceptionally large.” He compared the massive landslide to roughly 60 million medium SUVs tumbling down a mountainside.<br />
<br />
Mountainsides that were held strong by the heavy ice of glaciers become weak when the glaciers retreat. Erosion along with earthquakes are triggers that can cause the weakened slopes to collapse.<br />

It was first observed by Paul Swanstrom, pilot and owner of Haines-based Mountain Flying Service. Swanstrom noticed a huge cloud of dust over the Lamplugh Glacier during a flightseeing tour of Glacier Bay National Park several hours after the slide occurred.
