metachronistic

Another iPhone panorama, this time with the Pano app. I had been using AutoStitch, which makes panoramas from a series of existing photos. Pano takes a different approach: you shoot a series of photos, in order from left to right, from inside the app. After each image, the app asks if you’re happy with the shot, or if you’d like to retake it. If you’re happy with it, it stores it, and then shows you a semi-transparent slice of the right edge of the photo superimposed over the left side of the current camera viewscreen. This makes it fairly easy to line up each shot as you pan across your scene. When you’ve taken all the photos you want, the app joins the images together and saves it to the Camera Roll on the iPhone.

The upside to Pano is that it’s much easier to get well aligned images, as long as there’s enough contrast in the individual pictures to allow you to line them up as you’re shooting. The down side is that the only layout the app can handle is a single row of landscape or portrait shots. AutoStitch can join photos in any combination. The panorama at the bottom of my previous post (our back yard) was built from two rows of four photos (8 images total). The top row included a nicely exposed blue sky, and the bottom row was primarily the tussock–permafrost landscape of our backyard. Even though there are some obvious artifacts in the final image, it would be hard to get such a nice overall exposure with Pano and the iPhone camera.

Curious to find out how far up the overflow went, I rode my bike on the mushing trail upstream to Larry’s pond. It’s a quarter-mile bicycle ride, but is more like half a mile upstream from our house as the fish swim. As you can see from the panorama above, the overflow is upstream of this point. My foot broke through the ice while I was taking this photo and it was about 8 inches deep at the edge of the pond. The Creek is connected to the pond on the left side of the photo. If the blog sidebar is cutting into the photo, you may need to make your browser window wider. Click on the image for a very large (1400 pixels wide) version.

The photo was stitched together with the Hugin front end to panorama tools. The exposure of the right-most frame isn’t perfect, but that’s where the sun was, so I think it did an amazing job.

Yesterday afternoon while I was brewing beer (more on that later), I took Nika out for our usual walk. We go across the bridge, walk along the north side of the Creek until we get to the confluence of the Creek and the Slough (the “stick throwing spot”), then drop down onto the Creek and walk back. Typically we’ll walk under the bridge and come back up onto land near the red cabin. Yesterday we kept going another few hundred feet until we came across some overflow. It was only a few inches deep and didn’t seem to be advancing.

Last year we got some overflow early in the winter, but by January it seemed to have stopped and we didn’t get anymore until the Creek broke up at the end of April. This year it’s been lightly overflowing in spots around our house pretty much all winter. With all the late season snow, it’s been a good thing because it keeps the depth of the snow on the Creek lower than it would be. I did use snowshoes a couple times because the snow had gotten deep enough that it wasn’t fun to wade through, and Nika had a hard time swimming through it.

In the evening, I got up to get myself a Silver Gulch Hefeweizen, and was surprised to see running water over the whole length of the Creek. I went outside to investigate and take some photos. The water flowing over the ice was about 10 inches deep (you can see it in the photo of my boot on the right). The photo on the left (assuming you’re reading this on my blog and not in an aggregator…) shows what it looked like when I initially got out there.

I walked downstream through the overflow and came to the end of it near the stick throwing spot. It was pretty wild walking through almost a foot of water on top of the ice, and as I neared the bend at the slough, it started getting shallower and shallower. Eventually, I walked up onto the snow and took a few photos as the water advanced.

This morning the water level on top of the ice is up to 14 inches. The low temperature last night was -14°F (and it’s still -10°F as I type this), so the margins of the overflow are already frozen to around ½ an inch, and there’s steam rising from the flowing center. It’s great to hear flowing water again, but that much water suddenly appearing does make me a little nervous. We’re not in any present danger as the low point in the dog yard is easily three feet higher than the current level of the slough, but when a foot of water can suddenly appear over the frozen ice, who knows?

The top of the slough now has some water in it too, but I haven’t walked out on the trail to see how far the water has advanced. Depending on how much more water there is and the average temperature for the upcoming weeks, it looks like our walks on the Creek might be over for this winter. I’m curious to see how all the water will affect the breakup date this year. The weather service is predicting lows in the 20s and highs near 40 all week in Fairbanks, but that probably means lows near zero and highs barely above freezing here in the Valley, so breakup probably isn’t happening this week.

I just got back from walking Nika and Piper on the Creek. I’d looked at my GPS track from yesterday’s walk on the Creek and saw an obvious shortcut (from point A to B on the map) to cut off some distance. My objective was to take the Creek out to a section line (at points D and E—click on the image to see a full size version) that I also saw from the satellite imagery for the area, and wanted a way to make the route shorter. Yesterday’s walk was more than five miles, even though a raven could have covered the distance in a little over a half mile.

We walked down the Creek, came to the start of the shortcut at point A, walked overland through the forest to point B back on the Creek, and I immediately turned the wrong direction. I’d already walked about halfway back to point A before I realized I went the wrong way. Next time, turn left!

It is amazing how disorienting the Creek is, even with a GPS. Because it winds back and forth so much, even if you know where you’re going and can see it on the little map your GPS is showing you, it’s really difficult to tell if you are getting closer to your objective. The good thing is that the Creek only goes two ways. If you went the wrong way, just turn around and go back.

A week or so ago we got a weather station (it’s the thing at the top of the pole on the left side of the dog yard fence in the photo) so we can keep track of the weather at our house. We’re one of the coldest places in the Fairbanks area, so we’re excited to see just how different our weather is. We’re sending the data to the Citizen Weather Observer Program where it’s ingested, analyzed, and disseminated by NOAA. I don’t know if they use it in their forecasting, but we’ve already shown up in a few Public Information Statements from the local forecast office.

Full details on the station, with some plots and other data reports (I’m still working on most of these…) are at http://swingleydev.com/weather/dw1454/. The station code is DW1454 and shows up in MADIS as D1454.

We’ve had four days of nearly constant, heavy rain here in Fairbanks, and the levels of the Interior rivers and streams have come very close to the levels they reached in the Flood of ‘67. So we’re currently experiencing a 30-year flood event. The Tanana, Salcha, Chena and Nenana Rivers have all reached flood stages and many residents in low lying areas near these rivers have been evacuated. The photo on the right, taken by the National Weather Service, shows some of the flooding in the Rosie Creek area. Most of the larger rivers in town are six or seven feet above their normal summer levels.

The following plot shows the hourly and cumulative precipitation from the Small Arms Range (SRGA2) weather station over the past four days. Just under three inches of rain in four days doesn’t sound like a lot when you’re from other parts of the country, but Fairbanks gets an average of less than two inches a month in July and August, and our total annual precipitation (including snow) is only 10.87 inches of water. Much of the lower elevation and north-facing areas in the Tanana Valley are permanently frozen and this permafrost is quickly saturated with water. That’s why the region is so lush and green in the summer, despite almost desert-like summer rainfall totals. But once the ground is saturated, there’s nowhere for the water to go except into the streams and rivers. Usually flooding happens during breakup when all the melting snow runs off the frozen ground into the streams and ice jams in the rivers block the flow. Summer floods are more unusual.

Since Labor Day, 2007, we’ve been living around 30 feet away from a small stream, Goldstream Creek, which has risen between four and five feet since last week. If you look at my previous post, the log I’m resting my hand on in the photo is now completely submerged, which means if I were swimming out there today, the water would be over my head. The outside bank has slumped into the Creek in two places, but so far we haven’t lost any trees. The photo to the right shows the current water level, but even with the dramatic rise, it’s quite a bit below what it looked like during breakup this spring.

It’s really exciting living next to something that’s changing all the time like the Creek (plus, Kingfishers!). And now that we seem to have survived a 30-year flood event, I feel a little bit more secure that we’re not going to get inundated in the next high water event.

I’m looking forward to the Tanana Valley Fair, followed by a warmer, and drier August and September.

Once again, I’ve neglected my blog. My new job, the pressures of getting all our work done this summer, and the rest of life has kept me away.

Events: We’ve taken to swimming in the Creek. During the warmth of early June (which hasn’t returned since…) the Creek temperature rose to 65°F, and swimming was actually quite nice. I’m hoping we’ll get a few more warm days before fall so we can swim out there again.

Projects: I’ve made no progress at all on the new shed, but have repaired the bridge and got our digital antenna installed on the roof. I also replaced our chimney cap with the variety our chimney sweep prefers. Things left to do: Build the shed!, repair the glycol line that keeps the septic pipe thawed, fix and insulate the sewage treatment plant discharge pipe, reinforce the shed roofs, obtain and chop two more cords of firewood, install a heat shield behind the wood stove, get curtains for the two large downstairs windows and the sliding glass doors, and (finally) consider hiring a plumbing and heating company to replace and upgrade our system.

Books: I’ve read quite a few. Here’s a summary judgement on each:

• McSweeney’s Quarterly Concern, Volume 26: Enjoyable fictions, interesting format, no real standouts for me.
• The Rest is Noise: Fantastic look at the music and history of the 20th century. Alex Ross is one of my favorite New Yorker writers and this book doesn’t disappoint.
• Ambitious Brew: Interesting history of beer brewing in the United States. It dispels many of the classic beer myths (the most classic being that the big super-brewers ruined American beer, only to be “saved” by the micros), and tells a great story. Prost!
• Let the Northern Lights Erase Your Name: A very enjoyable book with a very memorable female lead. Vida has a great abbreviated and expressive way of writing that was refreshing.
• The Echo Maker: I’ve been looking forward to this one for so long, that I think the reading of it couldn’t be anything but a disappointment. I enjoyed it as a meditation on brain injury, but I felt like the characters were a little overwrought and stiff.

The rest: Andrea continues to progress toward her goal of running the Equinox Marathon. She’s out running sixteen miles (16 miles!) right now. I’m super proud of her. Meanwhile, I’ve been bicycling to work almost every day (13 miles round-trip) and the two of us are working toward doing 100 push ups in six weeks. Maybe by the next photo of me in the Creek, I’ll be ripped.

Probably not…

Buddy got some of his stitches out earlier in the week and was given permission by the vet to go for his first run of the year on Thanksgiving. Unfortunately, it was 34 degrees above normal yesterday and above freezing so we decided to take him out to the Creek instead. Piper and Nika have been going with me on most of my trail walks, but this was Buddy’s first experience off the leash. He was nervous at first, and kept running back to the dog yard, but eventually settled into it and had a great time warping around the Creek with the other dogs.

Nika was going crazy; click on the image below to see a close up of her craziness. Piper looks a little freaked out.
