  • Passengers on the Alaska Marine Highway System ferry, M/V LeConte, photograph the Eldred Rock Lighthouse, located on a small island in the Lynn Canal in southeast Alaska near Haines. <br />
<br />
Construction of the lighthouse was finished in 1906 after shipwrecks, notably the wreck of the Clara Nevada, occurred in the area during the 1898 Klondike gold rush. The light was automated by the U.S. Coast Guard in 1973 with the original fourth-order Fresnel lens moved to the Haines Sheldon Museum. <br />
<br />
In 2014, the Eldred Rock Lighthouse Preservation Association was formed to acquire, rehabilitate, and promote the lighthouse with the goal of establishing a visitor’s center and maritime museum. The Association for the Preservation of the Eldred Rock Lighthouse has been working hard to bring the lighthouse back to life, along with the history of the region.

  • The South Pier Lighthouse in Charlevoix, Michigan, is a favorite spot for tourists and residents wanting to catch a dramatic sunset. The lighthouse, located on Lake Michigan sits at the entrance of the Pine River Channel which provides access to Round Lake and Lake Charlevoix. The current 41-foot steel structure was built in 1941. From 1885 to 1914 the light was located on a wooden tower on the north pier. In 2005, the U.S. Coast Guard deemed the light as no longer needed and in 2008 transferred the Charlevoix South Pier Lighthouse to the City of Charlevoix under the National Historic Lighthouse Preservation Act.

  • The Kilauea Point Lighthouse, located on the northernmost point of the main Hawaiian islands on the island of Kauai, was built in 1913 as a navigational aid for commercial shipping between Hawaii and the Orient. It was deactivated in 1976 and replaced with an automated beacon for local boaters and aircraft. The lens of the lighthouse was designed by Augustin Fresnel and built in Paris, France. The lens was originally lit by a incandescent oil vapor lamp and could be seen 20 miles out to sea and 90 miles from the air. In 1930 a light bulb replaced the oil lamp, eventually reaching a wattage of 2,500,000 candle power. Originally, the 4.5 ton light assembly was rotated with a system much like how descending weights turn the hands on a cuckoo clock. These weights that would descend the center of the lighthouse would have to be pulled up by the lighthouse keeper ever 3.5 hours. Eventually a motor replaced the weight mechanism. People pictured are unidentified.

  • This aerial photograph of a portion of the "Council Grounds" is the primary area where bald eagles gather on the Chilkat River in the Alaska Chilkat Bald Eagle Preserve near Haines, Alaska. Bald eagles come to the alluvial delta area at the confluence of the Tsirku (center) and Chilkat (left to right) Rivers because of the availability of spawned-out salmon and open waters in late fall and early winter. 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. Photographers come to the Chilkat River in November and December to photograph one of the largest gatherings of bald eagles in the world. In 1982, the 48,000 acre area was designated as the Alaska Chilkat Bald Eagle Preserve. In the background are the mountains that make of the Takhin Ridge and Takhinsha Mountains. Chilkat Lake is pictured on the left, below the mountains.

  • 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.

  • 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.

  • 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***

  • Death Valley National Park Visitors come not only to experience the record heat but also the beauty. Despite the desert conditions, the park is known for its spring wildflowers. Under perfect conditions, the park experiences a rare event known as a wildflower "super bloom" which produces a sea wildflowers. Most of the desert wildflowers are annuals. This ensures their survival as this allows them to lie dormant as seeds during times of drought. Here, the golden light of sunset bathes Desert Gold, also known as Hairy Desert Sunflower, in Death Valley National Park.<br />
<br />
Death Valley National Park, located in eastern California near the border with Nevada is one of the hottest spots on earth, holding the hottest recorded air temperature of 134 °F. The Park also is location of the lowest spot in North America, 282 feet below sea level at the vast salt flats at Badwater Basin. At 3.4 million acres, the park is the largest national park in the contiguous United States. Death Valley National Park sits between the Panamint Range on the west  and Amargosa Range on the east.

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***

  • Rockweed (Fucus distichus) is a seaweed found in the middle intertidal zone of Glacier Bay National Park. According to the park’s website, "Gas-filled bladders at the tip of each branch help keep the plant floating near the surface when the tide is in, and thus increases the amount of light available for its energy needs. Light is filtered out rapidly as it passes through water. Rockweed also secretes a mucus-like substance which helps keep it moist during low tide."<br />
<br />
Glacier Bay National Park is located in southeast Alaska. The park is also an important marine wilderness area known for its spectacular tidewater glaciers, icefields, and tall coastal mountains. The park a popular destination for cruise ships is also known for its sea kayaking and wildlife viewing opportunities. <br />
<br />
Glacier Bay National Park is home to humpback whales which feed in the park's protected waters during the summer, both black and grizzly bears, moose, wolves, sea otters, harbor seals, steller sea lions, and numerous species of sea birds. <br />
<br />
The dynamically changing park, known for its large, contiguous, intact ecosystems, is a United Nations biosphere reserve and a UNESCO World Heritage site.

  • Visitors to the Flint Hills Discovery Center watch the 15-minute ‘immersive experience’ film which has special effects such as smoke, fog, mist and wind which appear in the theater as the high definition film is shown on a large panoramic screen at the $24.4 million center, located in Manhattan, Kansas. This scene in the movie depicts fireflies (also known as lightning bugs) flickering in the early evening light on the tallgrass prairie. Through interactive exhibits, Flint Hills Discovery Center visitors can explore the science and cultural history of the last stand of tallgrass prairie in North America – one of the world’s most endangered ecosystems. Other attractions of the Flint Hills Discovery Center include: an ‘underground forest’ depicting the long roots of prairie plants including the 7-foot roots of bluestem prairie grass; explanations of importance of fire to the Flint Hills tallgrass prairie; and exhibits about the people and cultural history of the Flint Hills. The Flint Hills Discovery Center was designed by the museum architectural firm Vern Johnson Inc. with interpretive design and planning by Hilferty and Associates. The 34,900 square foot science and history learning center features permanent interactive exhibits, temporary exhibits, and areas for community programs and outreach activities. The Flint Hills Discovery Center received a LEED green building certification for their environmental design and energy efficiency, including their lighting and geothermal heating/cooling system.

  • Participants in "Flames in the Flint Hills" light fires across the prairie grass of the Flying W Ranch near Clements, Kansas. This agritourism event allows ranch guests to take part in lighting the prescribed burns. Prairie grasses in the Kansas Flint Hills are intentionally burned by land mangers and cattle ranchers in the spring to prepare the land for cattle grazing and help maintain a healthy tallgrass prairie ecosystem. The burning is also an effective way of controlling invasive plants and trees. The prairie grassland is burned when the soil is moist but grasses are dry. This allows the deep roots of the grasses to survive and the burned grasses on the soil surface return as nutrients to the soil. These nutrients allow for the rapid growth of new grass. After approximately two weeks of burning, new grass emerges. Less than four percent of the original 140 million acres of tallgrass prairie remains in North America. Most of the remaining tallgrass prairie is in the Flint Hills in Kansas.

Glacier National Park in the Rocky Mountains of Montana encompasses more than 1 million acres. The park’s nickname is the “Crown of the Continent Ecosystem.” The park was established in May 1910. Soon after, hotels and chalets were established in the park, including the Lake McDonald Lodge. In 1932 construction began on the Going-to-the-Sun Road, allowing automobiles to traverse the park. Climate change is affecting the park. As of 2010, only 25 active glaciers remain in the park, down from the 150 that existed in the mid-19th century.
