The Fisher Covered Railroad Bridge is one of Vermont's two remaining railroad covered bridges. It spans the Lamoille River southeast of the Wolcott Village Center, just off VT Route 15. The posted coordinates identify a small parking area north of the bridge and a place to learn how to find the final cache.
According to Wikipedia:
The bridge is a two-span doubled Town lattice truss, with a total length of 103.5 feet (31.5 m) and a width of 20.5 feet (6.2 m), with an inside track width of 15 feet (4.6 m). It rests on stone abutments capped in concrete. The bridge is covered by a gabled roof which has a distinctive central monitor for much of its length. The exterior of the bridge is clad in vertical board siding which rises most of the way to the roof, leaving an open strip at the top of the sides. The siding extends into the portals a short way, and there is a band of skirt-style siding extending below the main siding. The decking now has a steel I-beam substructure, leaving the trusses to only support the superstructure.
The bridge was built in 1908, and was, at the time of its listing on the National Register in 1974, the last covered bridge in the United States to carry railroad traffic. It was built by the Boston and Maine Railroad on the route of the St. Johnsbury and Lamoille County Railroad, which it controlled. In 1968, it was threatened with demolition in favor of a steel truss. A pier was built under the bridge, and four steel girders were installed to support the bridge's load.
The bridge can be accessed directly from the parking area or by following the wider more gentle path that wends its way to the Lamoille Valley Rail Trail (LVRT). No matter which way you take, there will be a bit of terrain to deal with to get to the cache.
When we were in Copenhagen, Denmark, there were caches that required arranging numbers using what was galled a Gade Calculation. You'll need to arrange some digits according to that structure.
This is the description of the Gade calculation lifted pretty much directly from a multi we did while in Copenhagen:
GADE Calculation - explained
To find the geocache, you have to find some digits.
When you have found the digits, do this:
Sort the individual digits - low to high.
If, for instance, the digits you found were 6, 17, 9 and 6 sort the digits like this: 16679
Then complete the line, with the missing digits 16679023458.
Now you have: a=1, b=6, c=6, d=7, e=9, f=0, g=2, h=3, i=4, j=5 and k=8
Remember to repeat any identical digits you may have found.
To find the cache, look for the two years noted on the Vermont Historical Marker at the posted coordinates. Arrange the digits from the two 4-digit years on the marker according to the Gade calculation explanation.
The cache is at: N 44 JC.HJB W 72 IL.DDA
Can you catch the cache?
Congratulations to mwein for being FTF!
