The Silver Falls Loop is a notable trail in Mt. Rainier National Park. Aside from the falls and river, it features a traverse of a wonderful forest.

A shot 3 years in the taking, One I wanted to take on the Star Adventurer but never could Barnard's Loop. Polar alignment and Guiding where the two biggest problems. This is a Wide field of the Orion area with a Nikon 50mm G F1.8 lens but will try again once I can get my parents Nikon 50mm D F1.8 lens with a manual aperture ring. This was taken over 5 night and dumped a lot of shot as the lens is so wide field the city light made it into the shot, in the end it was start after 9 pm finish 2am. Orion was corrected with 5min and 2 min shots

Making its debut at the 1989 Münich Oktoberfest, Olympia Looping remains the largest and most thrilling traveling roller coaster in the world. It's an Anton Schwarzkopf classic.
Soybean Looper (Chrysodeixis includens) – Hodges#8890
These moths were all over the flowers at Cape May Point State Park and the Meadows. Despite their numbers, they were pretty difficult to photograph since they rarely stopped moving for long and tended to hover for nectaring rather than land.

With 40 loads in town, the Port Harbor Job rolls around one the two different loops that the railroad uses to shuffle cars around the Port. This was part of a 70 unit grain train that was delivered to the PHRR to be unloaded here in Granite City and transferred to barge, which is right behind me. The crew ill pull clear of two crossings, tie the 2758 down and then head back to the shop area to grab the MP15 number 1296 to spot the other cut.

Georgetown loop railroad, Georgetown, Colorado
The Georgetown Loop Railroad was one of Colorado’s first visitor attractions. This spectacular stretch of 3 ft (914 mm) narrow gauge railroad was completed in 1884 and considered an engineering marvel for its time. The thriving mining towns of Georgetown and Silver Plume lie 2 miles (3.2 km) apart in the steep, narrow canyon of Clear Creek in the Rocky Mountains west of Denver. Engineers designed a corkscrew route that traveled nearly twice that distance to connect them, slowly gaining more than 600 feet (183 m) in elevation. The route included horseshoe curves, grades of up to 4%, and four bridges across Clear Creek, including the massive Devil’s Gate High Bridge.
The Georgetown, Breckenridge, and Leadville Railroad had been formed in 1881 under the Union Pacific Railroad.[5] The Loop portion of the line was the crowning segment of the line, crossing the top of the gorge on a 95-foot (29 m) high trestle.
Originally part of the larger line of the Colorado Central Railroad constructed in the 1870s and 1880s, in the wake of the Colorado Gold Rush, this line was also used extensively during the silver boom of the 1880s to haul silver ore from the mines at Silver Plume. In 1893, the Colorado and Southern Railway took over the line and operated it for passengers and freight until 1938.
Between 1906 and 1918, the Georgetown Loop connected with the Argentine Central Railway in Silver Plume, by which tourists could continue onward to the summit of Mount McClellan. Prior to 1916, the Argentine Central also served several large silver mines on the east side of Argentine Pass.
The line was later dismantled, but was restored in the 1980s to operate during summer months as a tourist railroad, carrying passengers using historic 3 ft (914 mm) narrow gauge steam locomotives.
UP 4686 leads a long southbound intermodal train around Tehachapi Loop. At the time Walong siding still existed at the loop. Today this view would include a second main track (Main 2) where the access road is located to the right of the train. This effectively eliminated Walong siding and replaced it with two main tracks through this area.

Yes, I was at the Roskilde Airshow in August. Lots of planes and cool displays. This was one of the better ones. The German Air Force Airbus did a loop, not a complete one but a backside loop...like! Took a series of shots of the loop and have put it together here in a slightly compressed form.
It is a large, heavy aircraft and the fact that the pilots did a loop at a relatively low altitude in front of an audience of several thousand was nothing short of impressive in my eyes.
The pilots of course did more than just the loop, among other things they landed the plane in less than 200 meters and with everything together the display showed enormous skill on the part of the pilots, but also an unusually agile and easy-to-handle aircraft for its size.
Impressive!

Just south of Park City, UT is the Alpine Loop, Miles of trees and especially Aspen groves. A must see when in the Park City area.
The Cygnus Loop
50+ hours of integration time. 28 different image panels. 3 years in the making!
Found directly overhear in mid to late summer in midnorthern latitudes, the Cygnus Loop spreads its gassy tendrils across the sky. It can be found in the dusty lanes of the Milky Way just by the wing of Cygnus, the swan, glowing in various parts of the electromagnetic spectrum. The nebula complex is located about 2500 LY from Earth and spans 130LY and contains several named "objects" like the Eastern Veil (Witch's Broom). Pickering's Triangle, and the Western Veil. These gassy wisps are all that remain of a star that went supernova about 21000 years ago, spreading its enriched guts across the galaxy.
The bulk of this project was shot in the summer of 2019. I've now revisited with fresh eyes, new tools, and an improves post processing skillset. I've added more data to it than the original, going back and finding other images I'd previously shot of various parts of the nebula, and integrated them into this new image. This image combines nearly 50 hours of integration time with over 20 individual panels to complete the mosaic. The result is a large 56 Megapixel size image of one of the largest deep sky objects in our night sky.

Norfolk Southern Asheville based local P87 drops down the famed 'Old Fort Loops' on their daily run from Asheville to Bridgewater and back. With the closing of the Asheville to Linwood portion of the S-Line as a mainline route locals P87 during the day and P60 at night are the only two trains that traverse this famed stretch of track. Here the train navigates through one of the many rock cuts in the loops, as it prepares to duck into one of the many tunnels in the loops.
