  • In 2001, a 44-year-old pregnant whale was struck by and killed by a cruise ship in the waters of Glacier Bay National Park and Preserve. As part of a legal settlement with the cruise line, her skeleton was used to make one of the world’s largest humpback interpretive displays. The whale, given the name “Snow”, was 45.5 feet long and weighed 35 tons at the time of her death. Snow’s death contributed to research that helped settle the scientific question of how long humpbacks can live, now believed to be up to 96 years.<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.

  • A kayaker kayaks past a small iceberg floating in the Muir Inlet of Glacier Bay National Park. This piece of glacial ice is technically not an iceberg due to its small size. The size category for an iceberg is huge, with the height of the ice must be greater than 16 feet above sea level, a thickness of 98-164 feet, with a coverage area greater than 5,382 square feet. Next size down is bergy bits (height less than 16 feet above sea level but greater than three feet), then growlers (less than three feet above sea level - the size of a truck or grand piano), and then brash ice.<br />
<br />
The piece of ice is from the retreating McBride Glacier. Recent research determined that there is 11% less glacial ice in Glacier Bay than in the 1950s. Still, even with the earth’s rapidly changing climate, Glacier Bay is home to a few stable glaciers due to heavy snowfall in the nearby Fairweather Mountains. <br />

  • A moss-covered boulder is lit by a sliver of sunlight along the 4.5-mile roundtrip Avalanche Lake Trail.<br />
<br />
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.

  • The Saksaia Glacier sits at the top of the Glacier Creek valley near the location of the potential mine site being explored by Constantine Metal Resources Ltd. of Vancouver, British Columbia along with investment partner Dowa Metals & Mining Co., Ltd. of Japan. The area of exploration, known as the Palmer Deposit is located near mile 40 of the Haines Highway and the Porcupine placer gold mining area near Haines, Alaska.<br />
<br />
The minerals that Constantine’s drilling explorations have found are primarily copper and zinc, with significant amounts of gold and silver. Exploratory drilling to refine the location and mineral amounts are the current focus of the company.<br />
<br />
If approved and developed, the mine would be an underground mine. Besides the actual ore deposits, having the nearby highway access for transporting ore to the deepwater port at Haines is also attractive to Constantine.<br />
<br />
Support for a large scale mine such as the Constantine project is divided among residents of Haines, a small community in Southeast Alaska 75 miles northwest of Juneau. The community’s needed economic boost from jobs, development and other mine support that a large-scale mine brings is tempting to some. To others, anything that might put the salmon spawning and rearing habitat and watershed resources at risk is simply unimaginable and unacceptable. Of particular concern is copper and other heavy metals in mine waste leaching into the Klehini and Chilkat River. Copper and heavy metals are toxic to salmon and bald eagles.<br />
<br />
The Chilkat River chum salmon are the primary food source for one of the largest gatherings of bald eagles in the world. Each fall, bald eagles congregate in the Alaska Chilkat Bald Eagle Preserve, located only three miles downriver from the area of current exploration. At times more than 3,000 eagles have been recorded at the primary gathering area for the fall chum salmon run.

  • This abandoned building sits in the rainforest at the site of a historic fox farm on an unnamed island in the Beardslee Islands in Glacier Bay National Park and Preserve. Several significantly damaged small cabin-like buildings are all that remain of the operation. Fox farming in Southeast Alaska began in the early 1900s with the introduction of Russian arctic foxes, which were prized for their snow-white fur. The Great Depression caused most of the fox farms to cease operations. The National Park Service reminds visitors not to take or move historical objects, and that weather-damaged structures like those found at this site should not be entered due to the likelihood of imminent collapse.<br />

  • A male lesser prairie-chicken performs his mating display on a lek located on the Hoeme Family Farm and Ranch in Gove County, Kansas. Prairie chickens return to the same lek year after year to mate. Males attempt to entice female lesser prairie-chickens with a showy mating display on a lek.<br />
<br />
In 2023, lesser prairie-chickens officially became a federally threatened species in Kansas, Colorado, Oklahoma, and northern Texas. The population in New Mexico and western Texas was given endangered status with about half of the current population living in western Kansas.<br />
<br />
Lesser prairie-chickens are threatened by climate changes (drought or too much rain) and habitat loss. In particular, habitat loss caused by wind energy development. Prairie-chickens need large expanses of open grassland without tall objects (like wind turbines or power lines and power poles) that provide a raptor to perch on.<br />
<br />
During courtship on a lek, males inflate their red esophageal air sacs and hold erect pinnae on each side of the neck. They rapidly stomp their feet making a drumming-like sound. The booming call of lesser-prairie chickens, amplified by the air sacs, can be heard as far as a mile away.

  • Three male Columbian sharp-tailed grouse perform a mating dance on a lek 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 medial moraine is formed when two glaciers meet and the debris on the edges of the adjacent valley sides join and are carried on top of the glacier. <br />
<br />
The McBride Glacier, the most active glacier and only tidewater glacier in the Muir Inlet, is retreating.<br />
<br />
Glacier Bay National Park is located in southeast Alaska. Known for its spectacular tidewater glaciers, icefields, and tall costal mountains, the park is also an important marine wilderness area. 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's 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.

  • A male lesser prairie-chicken (Tympanuchus pallidicinctus) attempts to entice female lesser prairie-chickens at sunrise with a showy mating display on a lek near the Smoky Valley Ranch in Logan County, Kansas. Prairie chickens return to the same lek year after year to mate. Males will battle each other to have the prime spot on a lek.<br />
<br />
In 2023, lesser prairie-chickens officially became a federally threatened species in Kansas, Colorado, Oklahoma, and northern Texas. The population in New Mexico and western Texas was given endangered status with about half of the current population living in western Kansas.<br />
<br />
Lesser prairie-chickens are threatened by climate changes (drought or too much rain) and habitat loss. In particular, habitat loss caused by wind energy development. Prairie-chickens need large expanses of open grassland without tall objects (like wind turbines or power lines and power poles) that provide a raptor to perch on.<br />
<br />
During courtship on a lek, males inflate their red esophageal air sacs and hold erect pinnae on each side of the neck. They rapidly stomp their feet making a drumming-like sound. The booming call of lesser-prairie chickens, amplified by the air sacs, can be heard as far as a mile away.

  • Fall colors and a scenic view of Mt. Emmerich greet visitors to Haines, Alaska. Haines is a cruise ship destination on the Lynn Canal in southeast Alaska. The Haines Highway provides road access to the continental highway system. The photograph was taken at Picture Point on AK-7 (Lutak Road).<br />
<br />
Haines, Alaska, a picturesque town in southeast Alaska, is located on the Lynn Canal between the towns of Skagway and Juneau. Haines is one of the few towns in southeast Alaska that is connected with the North American highway system. The Haines Highway (Alaska Route 7 or AK-7) travels through British Columbia and the Yukon (Yukon Highway 3) to connect with the Alaska Highway in Haines Junction, Yukon.<br />
<br />
Haines is also a stop on the Alaska Marine Highway System with ferries arriving from Skagway and Juneau.<br />
<br />
Wildlife viewing opportunities are abundant. The Alaska Chilkat Bald Eagle Preserve on the Chilkat River, near the confluence with the Tsirku River near Klukwan, is famous for its large concentration of bald eagles in the fall. At its peak in November, the American Bald Eagle Foundation sponsors the Alaska Bald Eagle Festival.

  • Among the concerns related to the proposed Juneau Access Improvements Project is the Steller sea lion haulout at Gran Point (pictured). The haulout at Gran Point is a designated Steller sea lion Critical Habitat Area. According to the Alaska Department of Transportation’s 2014 Juneau Access Improvements Project: Draft Supplementary Environmental Impact Statement, more than one hundred Steller sea lions (Eumetopias jubatus) have been counted at the haulout during the spring and fall. As currently proposed the proposed highway would be built just uphill from the haulout area, approximately 100 to 600 feet horizontally and 50 to 100 feet vertically.<br />
<br />
Highway plans near the haulout includes blasting steep rock-cut embankments and several tunnels with one tunnel entrance only 550 feet away from the haulout. There is concern for haulout abandonment by the sea lions during highway construction as studies have shown Steller sea lions are very sensitive to noise, both in and out of water. Because Steller sea lions frequent Gran Point nearly year round, the use of explosives and helicopters will be challenging during construction.<br />
<br />
There are two distinct populations of Steller sea lions in Alaska. The majority of Stellar sea lions that frequent the Lynn Canal are part of the eastern population of Steller sea lions which are not listed as endangered under the Endangered Species Act; unlike the western population of Steller sea lions which are listed as endangered. That said however, there have been confirmed sightings of the western population Steller sea lions at Gran Point.<br />
<br />
The Juneau Access Improvements Project is a proposed $570-million highway project to extend Glacier Highway out of Juneau for closer road access to the southeast Alaska towns of Haines and Skagway. Juneau’s roads do not connect with the continental road network.<br />

  • 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.

  • Connelly Lake (center) is a 90-acre alpine lake near Haines, Alaska that drains into the Chilkoot River. Connelly Lake is the focus of a proposed $32 million, 12-megawatt hydroelectric project by Alaska Power and Telephone Company (AP&T). AP&T proposes to build a dam at the outlet of Connelly Lake that would create a 160-acre reservoir and a 6,200-foot-long penstock down the side of the mountain where water would be delivered to turbine generators located in a powerhouse near the Chilkoot River into which the lake water would be discharged. Some of the main features of the proposed Connelly Lake project (for example portions of the penstock, the powerhouse, access roads, and the transmission line) would be located in the Alaska Chilkat Bald Eagle Preserve and the Haines State Forest. Concerns include the impact construction and project operation would have on fish spawning and rearing habitat, and bald eagles. The eagles rely on the salmon that use the Chilkoot Valley in the fall and early winter when they are attracted to late spawning salmon runs. A hydro aquatic studies report prepared by the Shipley Group states that according to the Alaska Department of Fish and Game, 41 percent of the sockeye salmon in the upper Lynn Canal come from the Chilkoot River with 25 percent of those salmon spawning in the Chilkoot River drainage above Chilkoot Lake. The value of the fishery is estimated at more than $1,000,000 annually. AP&T announced in June 2013 that it was putting the project on hold citing difficulty securing funding from the Alaska Energy Authority and the lack of community support. Despite these setbacks AP&T says that it not abandoning pursuing the project. In early September 2013, the Haines Borough announced that it was exploring possibly filing for a preliminary permit now that the project was no longer being pursued by AP&T. This photo of the ice and snow covered Connelly Lake was taken in mid-July.

  • A kayaker kayaks past a small iceberg floating in the Muir Inlet of Glacier Bay National Park. This piece of glacial ice is technically not an iceberg due to its small size. The size category for an iceberg is huge, with the height of the ice must be greater than 16 feet above sea level, a thickness of 98-164 feet, with a coverage area greater than 5,382 square feet. Next size down is bergy bits (height less than 16 feet above sea level but greater than three feet), then growlers (less than three feet above sea level - the size of a truck or grand piano), and then brash ice.<br />
<br />
The piece of ice is from the retreating McBride Glacier. Recent research determined that there is 11% less glacial ice in Glacier Bay than in the 1950s. Still, even with the earth’s rapidly changing climate, Glacier Bay is home to a few stable glaciers due to heavy snowfall in the nearby Fairweather Mountains. <br />

During courtship on a lek, males inflate their red esophageal air sacs and hold erect pinnae on each side of the neck. They rapidly stomp their feet making a drumming-like sound. The booming call of lesser-prairie chickens, amplified by the air sacs, can be heard as far as a mile away.

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.

This photo shows a male Columbian sharp-tailed grouse with its distinctive orange comb and the purple air sacks that they inflate to amplify the courtship call and display their health. Also, note on the down-like feet the fleshy projections on their toes called pectinae. These help distribute the bird’s weight when walking on snow as snowshoes do.<br />

  • 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 />
This aerial photo of the Lamplugh Glacier landslide was taken two days after the landslide.

  • A male lesser prairie-chicken (Tympanuchus pallidicinctus) attempts to entice female lesser prairie-chickens at sunrise with a showy mating display on a lek near the Smoky Valley Ranch in Logan County, Kansas. Prairie chickens return to the same lek year after year to mate. Males will battle each other to have the prime spot on a lek.<br />
<br />
In 2023, lesser prairie-chickens officially became a federally threatened species in Kansas, Colorado, Oklahoma, and northern Texas. The population in New Mexico and western Texas was given endangered status with about half of the current population living in western Kansas.<br />
<br />
Lesser prairie-chickens are threatened by climate changes (drought or too much rain) and habitat loss. In particular, habitat loss caused by wind energy development. Prairie-chickens need large expanses of open grassland without tall objects (like wind turbines or power lines and power poles) that provide a raptor to perch on.<br />
<br />
During courtship on a lek, males inflate their red esophageal air sacs and hold erect pinnae on each side of the neck. They rapidly stomp their feet making a drumming-like sound. The booming call of lesser-prairie chickens, amplified by the air sacs, can be heard as far as a mile away.
