Riot of Color: The Fiery Hues of Alaska’s Malaspina Glacier


Satellite view of Malaspina Glacier on the southeastern coast of Alaska captured on October 27, 2023, by the Operational Land Imager-2 on Landsat 9.

An unexpected color palette reveals the features of an iconic glacial landscape in southeastern Alaska.

To human eyes, glacial ice typically looks white tinged with blue. But in this false-color satellite image, the rippled ice of Alaska’s Malaspina Glacier appears more fiery than frosty.

Satellite Imaging Reveals Unique Hues

This view of Malaspina Glacier on the southeastern coast of Alaska was captured by Landsat 9’s OLI-2 (Operational Land Imager-2) on October 27, 2023. The coastal/aerosol, near infrared, and shortwave infrared bands are displayed here: a band combination of 1-5-7. In this configuration, watery features are displayed in reds, oranges, and yellows; vegetation appears green; and rock is shown in shades of blue.

Malaspina Glacier: A Geological Marvel

The sprawling Malaspina Glacier—or Sít’ Tlein, Tlingit for “big glacier”—is located mostly within Wrangell-St. Elias National Park. At approximately 1,680 square miles (4,350 square kilometers) in size, it is the world’s largest piedmont glacier and covers an area larger than the state of Rhode Island. Its main source of ice is the Seward Glacier, which spills out of the St. Elias Mountains onto a broad coastal plain. Several other glaciers, such as the Agassiz, also fan out onto this plain and coalesce to form the larger Malaspina.

Moraines: Markers of Glacial Movement

The dark blueish-purple lines on the ice are moraines—areas where soil, rock, and other debris have been scraped up by the glacier and deposited along its edges. The zigzag pattern of the debris is caused by changes in the ice’s velocity. Glaciers in this area of Alaska periodically “surge” or lurch forward for one to several years. As a result of this irregular flow, the moraines can fold, compress, and shear to form the characteristic textures seen on Malaspina.

The Glacier’s Interaction With the Ocean

At the terminus, or end, of the glacier, a thin strip of land creates a barrier between the ice and the Gulf of Alaska. A comparison of satellite imagery over time has revealed a lagoon system forming along that barrier over the past few decades. Small patches of open water are visible here in a rusty red color. Some of this water is nearly as salty as the ocean, according to recent research, meaning that comparatively warm ocean water is making contact with the ice. This could lead to large-scale calving and hasten the glacier’s retreat.

Troopers release dash cam video of 2023 officer-involved shooting in Tok, say lethal shot was ‘allowed’ under Alaska law

Troopers release dash cam video of 2023 officer-involved shooting in Tok, say lethal shot was ‘allowed’ under Alaska law


TOK, Alaska (KTUU) – Alaska State Troopers released dash cam video and 911 audio Friday from an officer-involved shooting in Tok in October 2023 and said that the trooper who fatally shot a Northway man has been cleared of wrongdoing.

Viewer warning: The video in this story may be disturbing for some readers. Watch at your own risk.

The trooper involved was not wearing a body camera, according to the Department of Public Safety.

Phone records show that at 2:35 a.m. on Oct. 30, 2023, troopers received a call that 21-year-old Timothy Thomas of Northway was attempting to break into occupied motel rooms and making threats at the Three Bears Motel in Tok.

The caller relayed information to the Department of Public Safety:

Caller: “We were sleeping and we heard banging on the door.”

Dispatcher: “Oh he heard through somebody else that you guys were there, so he just showed up?”

Caller: “Yup and that’s a bottle of alcohol and blacked out.”

Dispatcher: “Okay.”

Caller: “He’s in the gray sweater.”

Dispatcher: “Okay, is he threatening anything?”

Caller: “To break down the door.”

Troopers say the same caller called dispatch four times as Thomas tried to break the window and get into other motel rooms.

Trooper Timothy Rosario arrived just after 3 a.m. and saw Thomas was carrying an AK-47 style rifle outside the motel.

Officials say the dash cam video has no audio due to the in-car video recording being activated after the shooting, and Rosario was unable to activate the video system in time.

Rosario gave Thomas multiple commands to stop, but he refused stating, “I’d rather not.”

Troopers say Thomas appeared to be approaching a “position of cover,” which they say would have put the life of the trooper and occupants in the motel at risk.

Rosario then shot Thomas three times and was declared dead at the scene.

The Office of Special Prosecutions reviewed the case, stating they would not be pressing charges against Officer Rosario, finding that use of force was lawful.

ANCHORAGE, Alaska (KTUU) – Rainy, windy weather greeted southcentral on Friday. Unsettled weather will keep a dearth of clouds, rain showers, even some snow showers over the state through the weekend. Temperatures cooled considerably along the north slope and interior with the rain’s arrival.

Southcentral is on the lucky end of the weather pattern, expecting to see clearing skies, drying conditions and sunshine into the weekend.

An upper trough is driving the wet weather across the state.

This is the first round of wet weather, with another big storm arriving over the Aleutians and western Alaska on Sunday. Southcentral can anticipate the return of wet weather by Monday.

Alaska State Troopers who were called to the village of Aniak on Thursday for reports of gunfire found a home engulfed by flames and later found human remains inside, they said.

Several people in the village had reported hearing random gunshots, although there were no reports of threats or anyone being shot at, said troopers spokesman Austin McDaniel. Aniak-based troopers and wildlife troopers were patrolling the village near the slough around 11:30 a.m. to try to find the source of the sporadic gunfire when they saw a house fully engulfed by flames, McDaniel said.

They worked with community members to suppress the fire, and later the remains of the homeowner were found inside, troopers said.

During the investigation, troopers identified the homeowner as the person suspected to be firing a gun, McDaniel said. The remains will be sent to the State Medical Examiner Office for an autopsy to determine the cause of death, McDaniel said.

The State Fire Marshal’s Office will investigate the cause and origin of the fire.

Aniak is situated along the Kuskokwim River roughly 90 air miles northeast of Bethel.
