On Mirror Pond, or, reflections on Turnagain Arm Alaska

Occasionally there are days when the wind does not blow through Turnagain Arm. Hard to believe because most folks who drive the Seward Highway are not on it everyday. So odds are, the few times they are out and about, the wind is blowing somewhere. As evidenced by these photos, I am offering proof that on this one day, the wind was not blowing gales through the passes. 

These images are from the pit of the Turnagain Arm between Girdwood and Portage Valleys. The view is across the Arm toward the Kenai Mountains around Hope, Alaska. This was a really frosty morning, so once the car engine warmed up, it was a cozy calm drive on the Highway. 

I encourage everyone with a little spare time to take a nice road trip this week or next weekend (the 27th & 28th) before the Highway becomes too crowded. Remember, the Portage Glacier Daylodge is open on the weekend from 10a to 5pm with fresh baked goods and sandwiches. After the Portage stop, cross over the highway to the Alaska Wildlife Conservation Center, the animals will appreciate your visit. Leave Anchorage or the Valley by 9a, it does not even have to be super early, and enjoy the mountains, the water, the eagles and all the other feathered migrants passing through south central Alaska. 

Thanks for reading and viewing! 

Girdwood and Portage, make it a two-fer!

Such a lovely blessing this high pressure continues to bring to south central Alaska. The bright blue skies, the blindingly white mountain tops, the clear air. Most of the air that is, with the exception of roadsides. Pedestrians are victim to the gravel dust being disturbed by everyone one out for a sunlit drive. 

If you need some encouragement for taking a scenic ride this weekend, the Portage Glacier Daylodge is open Fridays through Sundays in April until full time opening in May. Your lovely hosts are baking delicious treats such as cookies and cinnamon rolls and steaming up frothy lattes for your morning respite. If you are going to Alyeska for Slush Cup, just add an extra hour to your morning. The Portage Lodge opens at 10 am, you can have a quick late breakfast. Afterward, head back to Alyeska, the mountain does not open until 11 so nothing will be missed. The Portage Daylodge is only 15 miles from Girdwood, and a beautiful drive. Above is the view in Portage Valley with the Portage Daylodge to the right and the Begich-Boggs visitor center ahead. Below, Byron Glacier is still covered in snow as seen from the Portage Daylodge. 

While soaking in the views on your sunny jaunt through the mountains, be aware of the traffic. Our neighbors to the south are already streaming in for early season specials and all the adventure the great land has to offer. I have seen numerous small RV’s already camping out in Girdwood. On my drives along the Seward, there are countless boats being shuttled to water (mostly from the Valley I am guessing). Also be aware of late season snow machiners heading toward Turnagain Pass. The high pressure weather system has been holding the night temperatures down enough to keep the snow from melting rapidly. I imagine most of the snow is just evaporating under the dry air and sunny skies, oh, and the incredible winds. 

Snow rollers, rare phenomenon when wind, precipitation, and temperature are just right

We drove to Portage from Girdwood today to visit a friend and see her place. It was snowing, yes, and there was a winter weather advisory, yes, but it was not windy in Girdwood. We thought we could get over there, it is only 10 miles away, and back before the storm became too strong. We all should know better, there is no second guessing the weather when mountains are involved. 

As we neared Portage, we could tell the wind was stronger. It was so fierce in Portage (Bear Valley) that this amazing snow phenomenon was being formed. Driving down the Portage Glacier road felt like semi-controlled hydro-planing and the water was making a more dull sound against the under carriage of the car than what I am used to hearing from rain. 

After our visit in Portage, we realized we needed to drive back to Glacier Valley before sunset as the visibility was decreasing in Portage. As the car made its way back to paved road, I noticed the road surface was textured, not just wet and not just snow. You might even think it looks like a choppy lake surface. These photos reveal what the car experienced on the way out of Portage Valley: snow rollers! 

Of course I did not identify this cold weather phenomenon until I returned home and did some research. I believe these are miniature versions of larger snow rollers that occur on mountain sides or in fields. Wind blows snow that may be sitting on a layer of ice or frost that the snow does not stick to thus ‘rolling’ up like a carpet or a cinnamon roll. There are loads of photos of large dry snow rollers on the internet. I believe the phenomenon I saw in Portage Valley could also be classified as snow rollers.

The conditions in Portage Valley the day these snow rollers were captured: snow mixed with rain, temperature ranging from 29° to 34°, wind blowing with gusts to 60 mph. There was a layer of ice and water on the roadway when the snow began. The rare combination of the wind at just the right speed as snow hit the ice or water on the level road enabled the snow to collect and move in little cylindrical shapes across the surface. 

You can see tire tracks in the surface of the precipitation for scale. I literally had to hold on to the car to capture these photos. Gusts of wind were so strong I could have been blown over. Although I did not measure these little cylinders, I estimate them to have been 15 - 25 mm in diameter. If you look closely, you can see little caps on some rollers, like little waves, where the wind is moving the snow forward to roll again. 

After seeing these little slush rolls, I could understand why the sound on the under carriage of the car was deeper than rain would have been. What a cool learning experience and a testament to the effects of mountains on weather. The wind was channeled in just the right way through Portage yet not the same in Glacier Valley. Cool.
