Davidson Ditch.
"remnants of a project undertaken during the years 1924 to 1929 to bring water to the Fairbanks area gold mining operations. The operation was carried out under the auspices of the Fairbanks Exploration Company (known locally as F.E.), a subsidiary of United States Smelting, Refining and Mining Company (U.S.S.R. & M.).
This project, known as Davidson Ditch, was a 90-mile-long conduit designed to divert water from the Chatanika River [...] to hydraulic sluicing (stripping) operations at Cleary and Goldstream, just north of Fairbanks.
The term "ditch" does not do the project justice because, although the open earthwork section comprised most of its length, the course included a 0.7 mile long tunnel near Fox, and 6.13 miles of inverted siphons along the way. (Anyone who has tried to suck gas from a gasoline tank and drain it into a bucket through a hose knows what a siphon is. It carries fluid over a high point into a lower one. An inverted siphon carries fluid across a low point--in this case, a stream bed, back to a higher one.)
The inverted siphons, which are the pipes visible today, were masterpieces of engineering at the time." Alaska Science Forum
Paddy Gross at Woodward West ruining a scenic mountaintop photo by getting in the way and blasting a inverted tabe.
Little bit of shake during exposure shows up as something like a double exposure on the porch's uprights.
A few large flies were resting in the cool shadows behind my townhouse on a day I had off from work.

"Another name for Solar Inverter is PVInverter. The general function of an inverter is to take current from battery and convert current (AC) to run any common load. In this case, Solar panels are made to convert direct current from a photovoltaic array into alternating current .For more information visit www.ecosmart-solar.com

I developed my first roll of 120 film today and hung it to dry in the basement. Inverting the image revealed my cousin and his wife at Milikin University a couple months ago. I'll print up a proper version on paper one of these days. First I'll have to find a negative holder big enough. The film developed was Arista.edu, taken with a No.1 Pocket Kodak camera.

Architectural details of the walkway that runs along the periphery of the entrance that leads up to Spaceship Earth. I'm not sure what the purpose is of the inverted Ts, but they are intriguing.

Thanks for looking. I appreciate feedback!
I had heard about doing this to get low angle shots, but I had never tried it before. I removed the center shaft of my tripod and put it back in upside down. This way I was able to get a "creek level" shot of the bridge.
