Northern Alaska Is Operating Out of Rocks

Yearly, tens of millions of migratory birds flock to Alaska. Lots of of hundreds of caribou use the tundra, wealthy in flowers, as their calving grounds. Alaska’s North Slope can be wealthy in different pure sources: oil, gasoline, minerals. However one vital factor is missing: rocks. “Sure, gravel is a valuable commodity on the North Slope,” says Jeff Currey, an engineer with the state’s Division of Transportation and Public Services who works within the company’s Northern Area Supplies Part. For many years, Currey says, the state has been trying to find gravel all around the North Slope, with restricted success.

Gravel is important for every kind of long-term growth: constructing tasks, street building, runways, and different main infrastructure. “There’s an enormous want for gravel, and never a whole lot of it, is actually what it comes all the way down to,” says Trent Hubbard, a geologist with the Alaska Division of Pure Sources’ Division of Geological and Geophysical Surveys.

“We want roads. We want housing developments,” mentioned Pearl Brower, the president and CEO of Ukpeaġvik Iñupiat Company (UIC), primarily based in Utqiaġvik, throughout a panel dialogue eventually yr’s Arctic Encounter Symposium, the biggest annual Arctic-policy symposium in the US. Brower was amongst a handful of leaders from throughout the Arctic talking on the area’s future.

“I positively assume it’s type of a paramount necessity,” Brower mentioned. UIC runs a building firm that has accomplished greater than $1 billion in building tasks all through the US. The corporate’s web site boasts that it makes a speciality of distant places. Brower mentioned its tasks over the previous three a long time have exhausted two gravel pits, and the company is now growing one other. “You look throughout [Utqiaġvik] and we’re very gravel-based,” Brower mentioned. “You recognize, we don’t have pavement for probably the most half, and also you surprise, Wow, you already know, the place did all this gravel come from?

Ross Wilhelm—the undertaking superintendent at UIC Sand and Gravel, which opened a brand new pit final yr—says that if all of the tasks that at the moment require gravel from UIC’s pit are accomplished, it may very well be in operation for as much as 9 years.

In keeping with Wilhelm, local weather change is growing demand: Gravel is required for stabilizing present infrastructure because the frozen floor beneath it thaws, in addition to for a seawall to guard Utqiaġvik from excessive charges of coastal erosion. “I believe it’s an enormous issue,” he says. A five-mile-long sea wall was priced at greater than $300 million, in keeping with a 2019 feasibility research by the U.S. Military Corps of Engineers.

Gravel can also be a method to a richer financial future for Alaska’s North Slope. “To maintain the economic system rising, it’s so important,” Wilhelm says. Lots of the area’s residents dream of connecting a minimum of a few of its eight primary communities by street, however doing so would require plenty of gravel. The state and the North Slope Borough are partnering on a undertaking, the Arctic Strategic Transportation and Sources, or ASTAR, that would do precisely that. It’s been beneath analysis by state geologists since 2018.

The problem isn’t simply finding sufficient gravel for tasks similar to ASTAR; the price may also be exorbitant. Currey says he’s heard of different North Slope tasks the place the bids are as excessive as $800 a cubic yard for gravel. In Anchorage, a cubic yard of mixture gravel—the type used for constructing tasks—goes for about $15. “The DOT has paid on the order of a pair hundred {dollars} a cubic yard for materials being barged in, as a result of that’s the one solution to do it,” Currey says. A few of these barges come all the way in which from Nome, touring a whole bunch of sea miles north and east by way of the Bering Strait and up and into the Beaufort Sea to ship gravel.

Gravel can be a prized commodity for the oil and gasoline trade. Final yr, the Biden administration accredited ConocoPhillips’ Willow Venture, a decades-long oil-drilling effort within the Nationwide Petroleum Reserve. The controversial endeavor would require 4.2 million cubic yards of gravel for its three oil-drilling pads, in addition to sufficient for greater than 25 miles of latest street. A lot of that gravel will come from a 144-acre mine that ConocoPhillips will dig itself.

On the subject of gravel, the Willow Venture could fare properly, primarily on account of its geography; will probably be situated simply west of the village of Nuiqsut, the place there’s truly loads of gravel. Nuiqsut lies on the japanese aspect of Alaska’s North Slope, the place the Brooks Vary is nearer to the coast. Streams that run northward down the mountains carry gravel with them, in keeping with Hubbard.

However the North Slope is gigantic, spanning almost 95,000 sq. miles, and farther west, gravel sources dwindle: The mountains are farther from the coast, and gravel will get caught within the Colville River. “A lot of the fabric north of the Colville River is essentially silt and sand left over from historic sea-level rise and fall,” Hubbard says. It’s the type of materials that doesn’t work for tasks like Willow or the roads and essential infrastructure that communities depend on. “Gravel,” Hubbard says, “is only a actually onerous useful resource to seek out.”
