Yearly, thousands and thousands of migratory birds flock to Alaska. A whole lot of 1000’s of caribou use the tundra, wealthy in flowers, as their calving grounds. Alaska’s North Slope can also be wealthy in different pure sources: oil, fuel, minerals. However one essential 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 everywhere in the North Slope, with restricted success.
Gravel is important for every kind of long-term growth: constructing initiatives, highway building, runways, and different main infrastructure. “There’s a giant want for gravel, and never a number of it, is admittedly what it comes all the way down to,” says Trent Hubbard, a geologist with the Alaska Division of Pure Assets’ 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), based mostly in Utqiaġvik, throughout a panel dialogue eventually yr’s Arctic Encounter Symposium, the most important 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 suppose it’s type of a paramount necessity,” Brower mentioned. UIC runs a building firm that has accomplished greater than $1 billion in building initiatives all through the US. The corporate’s web site boasts that it makes a speciality of distant places. Brower mentioned its initiatives over the previous three a long time have exhausted two gravel pits, and the company is now creating one other. “You look throughout [Utqiaġvik] and we’re very gravel-based,” Brower mentioned. “You understand, we don’t have pavement for essentially the most half, and also you marvel, Wow, you realize, the place did all this gravel come from?”
Ross Wilhelm—the challenge superintendent at UIC Sand and Gravel, which opened a brand new pit final yr—says that if all of the initiatives that presently require gravel from UIC’s pit are accomplished, it may very well be in operation for as much as 9 years.
In line with Wilhelm, local weather change is rising demand: Gravel is required for stabilizing current 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 a giant 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 may be a method to a richer financial future for Alaska’s North Slope. “To maintain the financial system rising, it’s so very important,” Wilhelm says. Most of the area’s residents dream of connecting at the least a few of its eight foremost communities by highway, however doing so would require numerous gravel. The state and the North Slope Borough are partnering on a challenge, the Arctic Strategic Transportation and Assets, or ASTAR, that might do precisely that. It’s been beneath analysis by state geologists since 2018.
The difficulty isn’t simply finding sufficient gravel for initiatives corresponding to ASTAR; the associated fee may also be exorbitant. Currey says he’s heard of different North Slope initiatives the place the bids are as excessive as $800 a cubic yard for gravel. In Anchorage, a cubic yard of combination gravel—the sort used for constructing initiatives—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 strategy to do it,” Currey says. A few of these barges come all the best way 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 also be a prized commodity for the oil and fuel business. Final yr, the Biden administration permitted ConocoPhillips’ Willow Undertaking, 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 highway. A lot of that gravel will come from a 144-acre mine that ConocoPhillips will dig itself.
With regards to gravel, the Willow Undertaking might 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 jap 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 big, 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 initiatives like Willow or the roads and essential infrastructure that communities depend on. “Gravel,” Hubbard says, “is only a actually laborious useful resource to search out.”
