  • The conflict over putting in a hard-rock mine near the Alaska Chilkat Bald Eagle Preserve near Haines, Alaska took a new turn recently with the filing of a lawsuit by an Alaska Native Tlingit tribe and three environmental groups. The group is suing the Bureau of Land Management, saying that the agency granted mineral exploration permits without considering how a mine could affect the Chilkat River's salmon and the Alaska Chilkat Bald Eagle Preserve. <br />
<br />
Joining the Tlingit village of Klukwan in the lawsuit against the Bureau of Land Management are the Southeast Alaska Conservation Council, Lynn Canal Conservation and Rivers Without Borders. They are represented by Earthjustice, a nonprofit environmental law firm. The group is asking for mining permits to be revoked.<br />
<br />
Constantine Metal Resources Ltd. of Vancouver, British Columbia along with investment partner Dowa Metals & Mining Co., Ltd. of Japan is exploring a potential site, known as the Palmer Deposit for a mine (located upper center right) just above Glacier Creek (not visible) and the Klehini River (foreground). Pictured in the rear of the photo is Saksaia Glacier.<br />
<br />
Support for a large scale mine is divided among residents of Haines. The community’s needed economic boost from jobs 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 River (shown) and the Chilkat River 14 miles downstream. 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.

  • 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 (upper 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 Takshanuk Mountains. Chilkat Lake is pictured in the foreground. River on the left above the Tsirku River is the Klehini River which joins the Chilkat River right before the Tsirku River alluvial fan. Also pictured is Klutshah Mountain (top center), Iron Mountain and the village of Klukwan (in front of the left side of the alluvial fan).

  • Steve Lewis, Raptor Management Coordinator, U.S. Fish & Wildlife Service, places camouflage on a net launcher that he is using to capture bald eagles on the gravel bar of the Chilkat River. The net launcher, along with leg snare traps, is being used to capture bald eagles that will be used in a study being conducted by Rachel Wheat, a graduate student at the University of California Santa Cruz. 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. Pictured in the background is the Tlingit village of Klukwan. During late fall, bald eagles congregate along the Chilkat River to feed on salmon.

  • 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 />

Tender moment or just a stretch? While it is easy to anthropomorphize that these two bald eagles are sharing a tender moment, most likely the eagle is simply stretching or cooling off. Bald eagles do not sweat so to control their body temperature they often extend their wings. 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. <br />

Recently, Constantine Metal Resources Ltd. of Vancouver, British Columbia along with investment partner Dowa Metals & Mining Co., Ltd. of Japan have begun exploration for a potential site of a copper and zinc mine in the Klehini River/Chilkat River watersheds. Some local residents and environmental groups are concerned that a mine might threaten the area’s salmon. Of particular concern is copper and other heavy metals, found in mine waste, leaching into the Klehini River and the Chilkat River further downstream. Copper and heavy metals are toxic to salmon and bald eagles.

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 long line dangles from a helicopter above 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.

  • The conflict over putting in a hard-rock mine near the Alaska Chilkat Bald Eagle Preserve near Haines, Alaska took a new turn recently with the filing of a lawsuit by an Alaska Native Tlingit tribe and three environmental groups. The group is suing the Bureau of Land Management, saying that the agency granted mineral exploration permits without considering how a mine could affect the Chilkat River's salmon and the Alaska Chilkat Bald Eagle Preserve. <br />

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.

Recently, Constantine Metal Resources Ltd. of Vancouver, British Columbia along with investment partner Dowa Metals & Mining Co., Ltd. of Japan have begun exploration for a potential site of a copper and zinc mine in the Klehini River/Chilkat River watersheds. Some local residents and environmental groups are concerned that a mine might threaten the area’s salmon. Of particular concern is copper and other heavy metals, found in mine waste, leaching into the Klehini River and the Chilkat River further downstream. Copper and heavy metals are toxic to salmon and bald eagles.
