Did sea ice help populate the Americas?

Did sea ice help populate the Americas?


Human footprints preserved in mud at White Sands National Park in New Mexico suggest that humans arrived there — possibly via Alaska — at least 21,000 years ago.

No one alive today knows how people got that deep into North America from Asia so long ago. But a team of scientists has proposed winter sea ice as a possible ephemeral highway through and around Alaska and into the New World.

Summer Praetorius of the U.S. Geological Survey in Menlo Park, California, is lead author on a paper in which she suggests that ice that forms on the ocean might have been a platform that helped ancient people migrate southward.

Sea ice — which in winter forms off the coast of western and northern Alaska today — is just what it sounds like: ice that grows on the ocean surface in very cold places.

During winter, sea ice adheres to frigid shorelines of Alaska. It is sometimes fractured and bumpy, but often smooth enough for villagers in far-north communities to drive pickup trucks hundreds of miles from the termination of Alaska roads to their homes.

Praetorius and her colleagues are postulating that the first Americans might have used the same seasonal pathways to avoid giant, crevassed, ice sheets pressing down on North America at the time.

Walking over sea ice might also have presented an alternative to kayaking off the Alaska coast and facing intimidating ocean currents flowing northward.

Using computer models of ancient ocean-current flow, fossil remains of organisms that live on sea ice, and several other sources, Praetorius suggests there were two time periods that might have kind to migrating humans. Those featured a balance of enough sea ice for people to travel upon during winter as well as the presence of some land that was not under ice.

Those times were from about 24,000 to 22,000 years ago, and from 16,000 to about 15,000 years ago.

Both of those times were also within a period when the interior of the continent probably was covered with glacier ice. An oceanfront route might have been most feasible for travelers then.

Ancient people might have used sea ice as a bridge to “coastal areas and islands with a relatively traversable surface that doubled as a platform for hunting energy-dense marine mammals,” Praetorius wrote.

During the height of the last ice age, sea ice seems to have formed during winter on the Gulf of Alaska. Very little exists there today, even in winter.

Archeologists have not found ice-age weapons that people would use to harvest seals or bears, which would support the sea-ice-pathway theory. Praetorius thinks that may be because those tools are now deep under salt water.

She also thinks her sea-ice highway hypothesis is not mutually exclusive to other theories on how humans came to populate the Americas. Those other ideas include ancient boaters picking their way around ice sheets the way Glacier Bay kayakers do today. Another is that people scampered southward through an ice-free corridor that might have existed between the giant frozen lobes that flowed over much of North America.

Bear injures two US soldiers during military training in Alaska | The Jerusalem Post


Two US soldiers were wounded by a brown bear during a training exercise in Alaska on Thursday, the US Army stated.

Anchorage Daily News reported that the soldiers were from the 11th Airborne Division, and that the exercise had been a “land navigation training event” near Joint Base Elmendorf-Richardson.

State wildlife officials said that the bear attack seemed to be a defensive one, from a bear which had recently emerged from its den. Staff members from the Alaska Department of Fish and Game collected evidence at the scene in an attempt to learn more about the bear, such as its species and gender.

“The incident is currently under investigation, and we are working closely with installation authorities and local wildlife officials to gather all relevant information and ensure the safety of all personnel in the area,” the 11th Airborne Division said in a statement, reported ABC News.

ABC News also cited an 11th Airborne Division spokesperson, Lt.-Col. Jo Nederhoed, who said that the two soldiers had been seriously wounded, but were receiving care at a hospital in Anchorage, and had shown improvement by Saturday morning.

“We hope both individuals have a full and quick recovery, and our thoughts are with them during this time,” Fish and Game Regional Supervisor Cyndi Wardlow said in a statement reported by Anchorage Daily News. “In this case, having bear spray with them in the field may have saved their lives.” 

Both of the soldiers reportedly had and used bear spray during the attack.

The bear’s condition and whereabouts are currently unknown.

Travel prices are going up, up and away. Here’s what to watch.

Travel prices are going up, up and away. Here’s what to watch.


Up, up and away … that’s where most travel prices are going.

It’s true. Not only are our nation’s geopolitical thrusts in the Mideast affecting the cost of your fill-ups, every component of your trip from airfares to car rentals and hotel stays are subject to price hikes.

Imagine filling up a jetliner with jet fuel that’s doubled in price. It’s enough to melt your credit card, regardless of the number of points you get for every dollar spent!

Because the price of oil affects everything, higher prices are eating away at your travel budget in many ways.

Bag fees

There’s lots of press on this. All airlines are increasing their checked-bag fees because of the jump in fuel prices.

Back in 2009, Alaska Airlines instituted a $15 fee for the first checked bag and $25 for the second bag. At the time, there was no charge for the first bag and a second bag was $25.

Last week, Alaska Airlines, along with other major airlines, increased its fees to $45 for the first checked bag and $55 for the second bag. Delta Air Lines charges the same.

Even if the cost of oil comes down, I don’t expect bag fees will ever be reduced.

Travelers who live in Alaska are somewhat insulated from the new hikes because both Delta and Alaska Airlines offer two free checked bags, with conditions:

1. Alaska offers two free checked bags for travelers flying to or from Alaska who are enrolled in Club 49. This does not affect other flights on Alaska. Separately, ATMOS credit card holders can get a free checked bag. Also, elite members of the ATMOS scheme get one or two free checked bags systemwide.

2. Delta offers two free checked bags for travelers flying to or from Alaska who are SkyMiles members who live in Alaska. Again, this does not apply to other Delta flights. Separately, Delta American Express cardholders can get a free checked bag.

3. Elite-level travelers with the oneworld airline cartel, including Alaska Airlines, can get one or two checked bags on American, British Airways, Japan Airlines, Qantas or other oneworld carriers.

Main Cabin vs. Basic Economy

The spread between the lowest available price, Basic Economy, and a more flexible ticket, Main Cabin, has increased. While the difference used to be $20-$30 each way when the Basic Economy scheme was introduced in 2018, the round-trip upcharge now can exceed $100.

For example, the lowest Basic fare to Portland is $337 round-trip on Alaska Airlines. The upcharge to Main Cabin, with full loyalty points, pre-assigned seats and more flexibility on changes and cancellations, is $447, a 33% upcharge.

This trend is not specifically attributable to the new Iran War. It’s just a cost that continues to rise.

New fees

I’m impressed at the creativity of airline people who dream up new fees. Here are some of my favorites from Alaska Airlines:

1. Phone reservations: $15

2. Partner award booking fee: $12.50

3. Pet travel fee: $100 in the cabin, $200 in the baggage compartment with a kennel

4. Left on board item return fee: $20

On Condor Airlines, operating the only nonstop service from Anchorage to Europe, travelers can choose from four different bundles in economy class. The least-expensive, Economy Zero, from $840 round-trip, features fees for travelers:

1. Carry-on bag fee, up to 8kg: $35; a small bag like a purse always is included for free

2. Checked bag: $75

3. Airport check-in: $30

All three of these fees are included in the next-highest fare bucket, Economy Classic, from $900 round-trip. It’s cheaper to buy the bundle than it is to buy the components a la carte. Seat assignments are additional, from $25 for economy.

Airfares on the rise

There are a few good deals available for travel to select West Coast/Intermountain destinations in May, including:

1. Anchorage-San Francisco on Alaska Airlines, from $307 round-trip. Fly May 15-28 only. Add $90 round-trip for Main cabin.

2. Anchorage-Los Angeles on Alaska Airlines, from $317 round-trip. May 15-25 only. Add $90 round-trip for Main.

3. Anchorage-Phoenix on United, Delta or Alaska, from $267-$287 round-trip. Fly May 8-June 9 only. Add $90-$100 for Main.

4. Anchorage-Denver $357 round-trip on Delta. Fly May 8-June 9 only. Add $90 round-trip for Main.

For travel to other destinations, or later in the summer, be prepared to pay more.

Flying to Hawaii? Alaska Air’s nonstop prices out at $706 round-trip between May 30 and June 6. Add $110 round-trip for Main.

Nonstop flights from Anchorage to Salt Lake City start at $669 round-trip with Delta on May 17. That’s $100 more than the cost for the same flights last month. Add $90 more for Main.

Hotel costs continue to rise, accompanied by pesky resort fees.

The Outrigger on the Beach in Waikiki is a very nice beachfront hotel. It’s not plush, or the nicest property. But it’s solid. The cost is $334 per night.

But there’s more: a $50 per night resort fee, plus a variety of taxes and charges, totaling $112.55 per night.

Down in Seattle, the Sound Hotel in the Belltown neighborhood is marketed by Hilton. The discounted rate for “Honors” members — it’s free to join — is $313.34 per night for a king room in late May. Taxes and fees add an extra $56.40 per night.

There’s no appreciable bump yet for hotel rates as a result of the oil price surge. Yet. But if these hotel rates seem high, they’re in line with hotel rates in Anchorage this summer. At the Sheraton in Anchorage in June, it’s $450 per night, plus $54 in taxes and fees, when booked at Expedia.

Car rentals are not cheap

My go-to site for car rentals is the Costco site, which compares major brands and automatically includes Costco discounts.

In Las Vegas, for a one-day rental in May, Budget charges $67 per day, which includes taxes and fees of $22.77. In Anchorage, the same kind of car, medium SUV, costs $92.97 with Alamo.

The biggest differences so far in car rental rates seems to be the bill you’ll pay when you fill up the tank before returning. There’s no appreciable jump in prices because of the new war.

When it comes to making travel arrangements for the spring and summer, it’s more risky making completely non-refundable arrangements.

I made the decision to purchase most of my summer travel plans in advance, but only after determining I would not need to change the dates. Particularly with airline tickets, it’s expensive to change your dates.

There’s lots of uncertainty regarding travel arrangements, particularly international travel. As fuel prices go up due to oil shortages, travel companies will look for ways to recoup the increased costs. In most cases, those higher costs will be borne by travelers.

Murkowski warns decreasing national fuel prices could spell disaster for rural Alaska


ANCHORAGE, Alaska (KTUU) – The reopening of the Strait of Hormuz has led to a decrease in oil prices nationally, but Alaska’s senior senator said the state faces a different situation that could threaten rural communities.

“If you can’t produce power because you don’t have the diesel or you just can’t pay the prices, your little communities can collapse,” Sen. Lisa Murkowski, R-Alaska, said at a Friday press conference at the Arctic Encounter Summit in Anchorage.

The price of oil has been a double-edged sword for Alaska. On one hand, the increased price of North Slope oil brings more revenue to the state, but consumer prices can also rise.

North Slope oil prices were $106.36 a barrel on Thursday.

“This is a very precarious time,” Murkowski said. “Our state has enjoyed a bounty because we have benefited from the higher prices of oil that goes into our treasury, but it’s the Alaskans in … the off-road communities that are threatened to be hit most hard.”
