Your backward "L". I have seen similar to this quite often when shooting landscape up here in Alaska. They are too blurry to really identify correctly, but a good hazard guess, (somewhere around 90% correctly), Mosquitoes. (Could be some other flying insect.) Very easy to clone out when I don't want them but once in a while they do add to the picture story.

The Aurora brightness varies a lot. I have seen them when they were so dim my Canon 70D, Tonkina 11-16mm, ISO 26,000 would not capture them in under 35 seconds. (After 35 seconds you stars are streaks because of earth rotation.) During some much brighter storms I have gotten great pictures with less then 2 seconds and 3 seconds with same equipment and ISO at 400.

Aurora forecast. Try the following link.

You also need some clear sky. Partly cloudy can be OK depending on where the clouds are in relation to the aurora. For that I use the following link.
Fairbanks Clear Sky

Good luck. Check one of the online weather forecasts for the sunrise and sunset times for the Arctic Circle. It has to be "dark" 60 miles up before you can see the Aurora. Unless it is a really strong storm and they show up even in some sun glow below the horizon.

Great Aurora. I have been looking for these every night since last October. The nights that were clear there was no aurora activity. (Or I simply didn't get outside at the right time.) (I'm at Curry's Corner.

I have used Pelican for quite a number of years. Only one of them failed on me, a closing latch broke. It was 7 years old and I was sent 2 latches plus pins at no charge. Read the warrantee. ("...with exception for tornadoes, grizzly bears and 5-year olds."

Like MDI Mainer I use an Epson V550 and have been very happy with it. The Epson software works just fine for me but I use Adobe Photoshop 2020 with TOPAZ add-on apps to clean the ones that need it. I have cleaned a little over 2000 35-mm slides so far and have a bit over 30 trays (300 slides per tray) and 20 carousels, (some 80 some 140), to go.
You will find once scanned and zoomed up a lot of your slides will show dust specks, small hairs, etc. I began by using a lean eye-glass cloth and bulb blower you operate by hand. (It helped but was a lot of work and never cleaned them good.) I tried a few elaborate things to keep from spending more money. The last half of the cleaned slides I used PEC-12 and PEC PADS. A 2 oz bottle and 100 pads. A tiny bit goes a long way. I have cleaned over 300 slides so far and have not used half the PEC-12. Two small drops on 1/4 of a pad will easily clean 4 to 6 slides. It could be available elsewhere, but I ordered my from Adorama.

The Corydalis is a member of the Fumitory family which has a base in Europe. Most of it in North America has been introduced. Flowers on these plants are noted for one pedal having a larger base making it look somewhat like a dragon. When squeezed it will open and close the flower. Thus, the common name Dragon-flower.

Antirrhinum is part of the Poppy family.

Thank you for the suggestion but we have the both the red and blue Wild Columbine growing in our rock garden and it is not one of those. Mike, the reply below yours, knew it. It is a Pale Corydalis. I plugged that into a Google Image Search and my 26' monitor filled up with flowers just like the ones I have.

Mike - You hit it right on the nose. I did a Google Search, image, and I got a whole monitor full of the exact same flower and plant I couldn't find. Thank you very much.

I also enjoyed your information on the other plants. We have two of the Shooting Stars up here north of Fairbanks and up in the Brooks Range. One gets 7-8 inches high and the ones farther north or at higher altitudes are only half that tall if that much. I have pictures of Monkey flowers but I found those farther south in the Valdez area.

Thank you Linda. I looked up the Monkey Flower but the plant structure and leaf is entirely different between the two. Appreciate your attempt to help.

Thank you gwong1. It definitely is not the Shooting Star. I have quite a number of pictures of them. They have one flower per stem and only get half a high. Plus the flower look just like a shooting star where this "Bleeding Heart" does not have that shape at all.

I took these two pictures back in 1978 and 1980 using a Canon AE-1 film camera, 35-mm slide film. There isn't a whole lot of EXIF data associated with these images.

I have gone through 8 Alaska flower books and spent hours on the Internet searching under red flowers, yellow flowers, red and yellow flowers plus "Bleeding Heart" which way back then I labeled them. After searching the Internet I don't think that is the right name.

I took these two pictures in a road-side ditch in Alaska. I have forgotten where. But I have had three of these plants show up in the woods in my back yard in Fairbanks, Alaska, over a 50-year period. Almost every year I can find one or two when I am out in the wilds or watch as I drive the highways.

Thank you in advance. (I apologize for the quality of the photos - I was very much an amateur photographer in those years.)

Thank you Mike for taking me on a few memorial hunting trips. Each of the pictures, except for the last one, looks almost just like a place I have seen over the years of hunting in Alaska. I see little differences the tell me it definitely the same place, but I can just ignore those and enjoy the memorable joys of that trip. If you would clone a few clouds over the mountains in the last picture so they were not recognizable I could enjoy memories of that scene also.

Always enjoy you picture Mike. Keep up the good work.

The Anchorage Daily News just had an article about the Denali National Park. The slide at 43 mile has been a problem that has closed the road a number of times since 1916. This winter it has caused a large drop in the road. As of the publishing in the paper the Park Road will be closed at 30-mile until a solution can be found and completed. It is not up to the State of Alaska. This is a National Park and it has to be a National Park solution. The state is ready to aid and assist the park if needed.

The Park Service has stated they are going to have programs that will insure that visitors have a great trip.

The entry about the bus service being terrible. They are school buses with school bus seats. There are at least two different services available. The "brown" bus is a guided tour. There are a number of lengths for these tours. You stay on the bus, (there are rest stops along the way), and a guide tells you about things on the way. The "green" bus is a shuttle type. They also have different lengths and turn around a different places along the road. This bus, you can ask the drive and he will let you and your party off the bus anywhere along the way. It does not have to be a designated stopping place. You can then flag down another green bus going the direction you want and IF they have room they will pick you up. (They will not let you off the bus where a bear has been hanging around.) The driver will tell you he is there to make sure you enjoy a good trip and that the bus stays on the road. He does not have time to be looking for wildlife. If you see an animal, scenic view, or something shout out so he can hear you. Tell him which way you are looking. And the bus will stop. I have been on this shuttle bus 6 times. All six times I did see bear or bears if not right beside the bus then only a few yards away. Moose, Caribou, Fox, Lynx and wolf have been in ditch right beside the bus at times. It's a great way to see the park.

That being said - - be sure to check with the Denali Park Service about what is available this year. I do know that climbing and hiking permits have been canceled for 2020. There will be nobody climbing Denali or the other mountains this season. And as of a couple days ago they did not know if there will be any tours beyond 30-mile. (Most of the scenery and much of the wildlife is seen between 40 and 80 mile.)

I did not see any suggestion of the Denali Highway. That is the old access road to Denali Park before the Parks Highway was built. It connects between Paxson on the Richardson Highway and Cantwell on the Parks Highway. It is a gravel road with some pavement at each end. (One end it is 21 miles, I think that is the Cantwell end.) The total length is 135 miles and there are roadhouses at Susitna River, Maclaren River and Tangle Lakes. Lots of great scenery along this road.

Any of the highways that pass over high summits, (Parks, Richardson, Denali, Glenn and Dalton), should have or start having the fall colors in August and September. (Look at Mike's pictures on UHH when see Alaska Scenes. His icon is a fox.)

Thank you for the info. I forget what I paid for the PEC-12 but it was a 2 oz bottle and I see it cleaning 400 to 600 slides, (depending on just how dirty they are). At $33 for a 4 oz bottle, if that will clean 1200-1500 slides then it isn't really very expensive.

Thanks for the links Jerry. I already knew most everything that was covered, but I also learned a few more things about scanning slides. In a project like this one can always learn something that makes it just a tad easier or a little bit more efficient.
