Washington’s tallest mountain is shrinking with age


In a discovery that has literally changed the landscape of the Pacific Northwest, Mount Rainier—Washington state’s towering icon—has been found to be shorter than previously known.

A local scientist and mountaineer has confirmed that the volcano’s famous summit point has shifted and shrunk, marking a significant change in the mountain’s geography.

The discovery was made following a recent expedition to the summit by Eric Gilbertson, a teaching professor in mechanical engineering at Seattle University.

“Mt Rainier is the tallest peak in Washington, the most topographically prominent peak in the contiguous US, and the most heavily glaciated peak in the contiguous US,” Gilbertson wrote in a blog post.

“The peak is very significant in Washington—it is easily visible from Seattle on a clear day, and its picture is even on the state license plate and the state quarter. Some people refer to it simply as ‘The Mountain.’”

Using survey-grade GPS units borrowed from his university’s civil engineering department, Gilbertson found that the mountain’s official summit, known as Columbia Crest, is no longer the highest point on Mount Rainier.

On August 28, precise measurements revealed that Columbia Crest stands at 14,389.2 feet, while the southwest crater rim reaches 14,399.6 feet. This means Mount Rainier is approximately 10 feet shorter than its historically recorded height of 14,410 feet, which was first measured by triangulation in 1914 and officially established in 1956.

In total, the Columbia Crest has shrunk by 21.8 feet since 1998.

The reason for the shrinkage is relatively simple: ice is melting. “The summit area of Mt Rainier has a crater rim that melts out to rock every summer, but there has historically been a permanent dome of ice on the west edge of the rim,” Gilbertson said.

That ice dome is the Columbia Crest. Official measurements of a permanent ice cap such as this are usually made in late summer, when the ice cap is at its lowest point. Gilbertson added: “Measuring at this time of year ensures seasonal snow does not count towards the summit elevation.”

Gilbertson’s discovery came as part of his ongoing personal project to measure the exact heights of Cascade peaks, which he began in 2022. Reports from mountain guides who noticed that Columbia Crest, traditionally the summit where climbers pose for photos and plant their ice axes in triumph, no longer felt like the highest point sparked this particular expedition.

Despite their remarkable accuracy—the measurements have an error of just 0.1 feet—these new heights aren’t official just yet. The United States Geological Survey (USGS) still lists Mt Rainier as being 14,410 feet on its website.

Newsweek reached out to the USGS for comment via email outside of business hours.

Gilbertson didn’t point to a specific cause behind the shrinking, but climate change could play a key role. The mountain has undergone dramatic changes over the past century, with 42 percent of its glacier ice vanishing since 1896. At least one glacier has completely disappeared.

Based on his calculations, Gilbertson estimates that the southwest crater rim surpassed Columbia Crest as the highest point around 2014, a high-water mark in the mountain’s ongoing transformation.

Upriver Fire Near Spokane Triggers Evacuations For 12,000 Residents Amid Critical Fire Conditions

Upriver Fire Near Spokane Triggers Evacuations For 12,000 Residents Amid Critical Fire Conditions


Washington state is currently experiencing an early-season flare-up of wildfire activity, particularly in the southeastern and central parts of the state, as well as the Upriver Fire, a fast-moving incident East of Spokane.

A combination of an ongoing statewide drought emergency and critical fire weather—including a strong, dry cold front with high wind gusts—has caused several fires to grow rapidly over the last few days.

The most significant other current active blazes include:

Omak Lake Road Fire: Things are moving fast up there right now. As of this afternoon (Wednesday, June 17), the Omak Lake Road Fire has officially merged with the nearby Kartar Fire, creating a massive blaze that has already burned roughly 6,500 acres on Colville Reservation land.
Tule Fire (Yakima Region): Ignited on June 14 south of Toppenish, this is currently the largest wildfire in the state, having ballooned to approximately 20,665 acres with 0% containment. It is burning primarily in dry grass and brush and has been producing a massive smoke plume that is impacting air quality throughout the Columbia River Gorge.
Juniper Dunes Fire (Franklin County): This fire has burned over 10,577 acres and is 10% contained. It has pushed into the challenging, roadless terrain of the Juniper Dunes Wilderness area, making ground access difficult for crews.
A Red Flag Warning remains in effect across much of Eastern Washington due to sustained high winds and low relative humidity, meaning any ongoing fires face an extreme risk of rapid spread, and new starts can ignite easily.

Is smoke from around the state forecasted to arrive in NCW?

Right now, North Central Washington is in the clear. The active wildfire smoke is staying well away from the Wenatchee Valley and surrounding areas, and local air quality remains firmly in the “Good” category.
The main reason for this breaks down to wind direction and fire locations:
Westerly Winds are Our Friend: Strong winds blowing from the west across the Cascades are actively dispersing air over NCW and pushing regional smoke eastward.

Where the Smoke is Heading Instead:

South: Earlier this week, massive plumes from the Tule Fire down in Yakima drifted west/southwest into the Columbia River Gorge and Portland-Vancouver metro.
East: With the current wind shift, smoke from the large fires in the Columbia Basin (like Tule and Juniper Dunes) is now being carried east toward the Tri-Cities, Walla Walla, and the Palouse.
North/Northeast: Up north, the Kartar and Omak Lake fires east of Omak are causing localized downwind smoke impacts, but the smoke is drifting east toward Nespelem and the Coulee Dam rather than dropping south into Chelan or Douglas counties.
Because these breezy, dry conditions are expected to persist through the rest of the week, weather and air quality officials note that intermittent smoke impacts will mostly be a concern for communities situated directly downwind (east) of the active blazes.

Where can I look online to see where wildfire smoke is coming from?

A few years ago, I discovered a Canadian website that not only shows you where wildfire smoke is coming from, but also how the smoke forecast will affect you in the coming days. It comes from the BC Wildfire Service.
Click on this helpful wildfire smoke map and bookmark it.
A couple of things to know about this BC Wildfire Service website.
1) When you first find the smoke map, select the Smoke Forecast button.

The map will come to life, showing where current wind conditions are directing wildfire smoke and where it is forecast to travel in the coming days.
2) Since it’s a service of the BC Wildfire Service, it doesn’t provide any information on fires here in the US, but it does show where smoke is forecast to come from any wildfires north and south of the border.

Where can I find updated information about wildfires in Washington?

Eastern Washington wildfire forces evacuations and destroys homes


SPOKANE, Wash. — High winds drove a wildfire into a Spokane neighborhood, forcing the evacuation of about 1,200 people and potentially damaging or destroying up to 15 structures, according to fire officials.

The Upriver Fire started at 12:17 p.m. Tuesday near Upriver Drive in northeast Spokane, said Fire District 9 spokesman Robert Gray.

“It moved rapidly up the hill and once it reach the top the wind shifted and it went right into the Northwoods neighborhood,” Gray said. Fire crews from Washington state and Idaho attacked the fire from the ground and air, but it quickly grew to 225 acres (.35 square miles) in an area called Beacon Hill.

The blaze was 10 percent contained by Wednesday morning, according to a report by the National Interagency Fire Center. The wind had died down overnight, but the fire was still burning on the ground, so there was potential to expand on Wednesday, said Isabelle Hoygaard, a spokesperson with the Washington state Department of Natural Resources.

Black bear injures teen hiker in Washington state mountain area

Black bear injures teen hiker in Washington state mountain area


A black bear injured a teenage boy hiking in a mountainous recreation area outside Seattle on Tuesday, officials said, prompting a closure of the trail where it happened.

The boy was scratched when the bear charged and “swiped” at him in the early afternoon about 2.7 miles up Mount Si Trail, the Washington Department of Fish and Wildlife said.

He was one of three people hiking together along the trail in the the Mount Si Natural Resources Conservation Area, the department said in a statement.

“His injuries were very minor, but he was of course terrified,” King County Sheriff’s Office deputy Peter Linde told NBC affiliate KING of Seattle. “The bear tossed him around a little bit, but nothing serious. He’s on his way to the hospital right now to be checked out, get the wounds clean, and maybe get some antibiotics.”

King County Search and Rescue crews responded alongside the department’s own officers and transported the teen to a hospital for treatment, the fish and wildlife department said.

A separate group of hikers had another black bear encounter Tuesday when the animal followed them closely for “several miles,” the department said.

No other injuries were reported.

Fish and wildlife officials ultimately closed the Mount Si Trail so officers could search for the bear, it said.

The Washington State Department of Natural Resources said other nearby trails, including the Little Si and Mount Teneriffe trails and trailheads, have been closed “until further notice due to bear activity.”

“Please stay out of the area,” it said.

The state has recorded one death from a black bear encounter, in 1974. Twenty encounters have resulted in injury since 1970, the latest before Tuesday’s incident taking place in 2022, the Department of Fish and Wildlife said.
